Venture out on a timeless and breathtaking journey through the Kingdom of Lo; this off-the-beaten-path region was until recently a hidden Tibetan Buddhist enclave forbidden to foreigners. From the trail, expect incredible sights like sculpted canyons with wild rock formations, deep gorges, medieval villages, ancient fortresses, palaces, and mysterious, ancient cave hermitages. You'll also see the Tibetan Buddhist gompas and soaring snow-peaks that characterize this spectacular region, the "thumb" sticking up from Nepal into the Tibetan plateau.

Delightful experience · Nepal - Jan 15 - Jan 19, 2020
Firstly planning our trip with Kim Kim was a delight. The team really asked the right questions and understood what we were looking for in an itinerary.

My children and I had our health put at risk by the disgusting state of the accommodation on the trek. We were not told to bring bedding. We booked a luxury accommodation package at $20,000 usa for three people ( two of which were sharing a room) and 11 days. We were booked into accommodation with no running water no power and no heating. We had to beg every 30 minutes to keep the central wood burning kettle stove alight. We had no room heating in any lodge. The last... read more
Our private trek (EBC, Chola Pass, Goyko) · Nepal - Nov 16 - Dec 7, 2019
Our private trek (EBC, Chola Pass and Goyko lakes for two) was organised by Kripa last minute and was a fantastic experience. All went as planned and Kripa was accomodating to last minute changes. Our guide Rishi took expert care of us up the mountains and knew exactly how much we could do in one day adjusting the pace or the meal stops to our daily needs. I couldn’t recommend these two people highly enough. In addition to the trek when my partner fell ill in Kathmandu, Kripa was there... read more
Incredible Journey to Muldai Hill Sunrise · Nepal - Dec 23 - Jan 4, 2020
We are just getting back home from the most incredible trip that KimKim helped to arrange for us in coordination with Himalayan Trails which is their local group in Nepal. From the beginning we were looking for a custom tour of the country that would allow us to enjoy both some time on the mountain trekking as well as a resort. KimKim helped make it all work seamlessly throughout our time.
We were met at the airport in Kathmandu and together with our guide flew to Pokhara to begin the... read more

A Perfect 10 Days in Nepal
I truly had an amazing time. Kirpa organized the perfect trip which included a trek through the Himalayas and a short 2 day visit to the Chitwan National Park. My trek was exactly what I wanted-challenging! I was able to enjoy breathtaking views of the Himalayas. My guide and porter (both named Pemba) were professional, energetic, supportive and kind. I could not have asked for a better team.
I also greatly appreciated Kirpa's agility. She was nimble on her feet... read more
Trek to Khopra Danda · Nepal - Nov 26 - Dec 2, 2019
We had a wonderful time on our 7 day trek to Khopra Danda which we organised through Kripa from Himalayan Trails. She was so easy to deal with and informative. Our guide Tandu and porter Chhing were marvellous. They made sure that we were always looked after and comfortable. We had great weather and clear skies so the views of the Annapurna mountains was breathtaking. There was plenty of walking up and down hills so our trekking poles got plenty of use.

The Manaslu Trek was fantastic. Everyday was stunning new scenery, amazing people and fascinating villages. Amanda was brilliant at fielding all our questions and patiently allowing us to investigate all options before settling on a final itinerary. Sonam, our guide and her team were incredible. Calm, capable and great fun. They gave us an amazing insight into Nepalise life and were so open, friendly and encouraging. They really made the trip.
Manaslu Trek - Adventure of a Lifetime · Nepal - Oct 23 - Nov 6, 2019
Our trek in the Himalaya was an incredible experience and we were so happy that we decided to book with the KimKim/Himalayan Trails. Our local specialist, Kripa, was an invaluable resource as we tried to determine which trek was right for us. She was responsive, helpful, and always available to answer any and all questions we had while planning the trip and the KimKim interface made communication seamless and easy. Our guide, Nawang, was one a warm, kind, and fun-loving and companion on... read more

Took the Pikey Peak 8 day tour and was tailored to our requirements. Amanda was extremely helpful and professional throughout. The planning.The trek was superb and the guide and porter were absolutely fantastic . The whole team delivered a unique and 1st class unforgettable trip. I would not hesitate in using this team again in the future.
Incredible Manaslu · Nepal - Nov 5 - Nov 19, 2019
We had the most incredible Manaslu trek! It was brilliantly organised by Amanda who was incredibly informative and remained undaunted by our endless questions and changes to the itinerary. Our guide Sonem was just amazing and could not have been more caring and supportive. She really looked after us, trying so hard to secure the best accommodation and manage our expectations, checking the food and the kitchen at the tea houses, often cooking for us herself. She was so full of energy fun... read more
2 hikes while in Nepal · Nepal - Nov 1 - Nov 17, 2019
In general we think that the guides here are less professionell than in other countries. We had two different guides (Dawa and Pemba) and both experience were simillar. The guides here only give you information when you ask.
However it was always easy to communicate with Kripa. So with her we made good experiences.
We did like both treks so from the nature it was worth to visit Nepal.
Nepal & Muldai Trek · Nepal - Oct 29 - Nov 5, 2019
This was our first time using KimKim but it has been a very positive experience and I would not hesitate to recommend it to others. Himalayan Trails were our tour agent and from the outset they were nothing but efficient helping us to plan exactly what we wanted from our trip. Amanda was quick to respond to any queries and provided lots of additional useful information to ensure we were well prepared in advance. The accommodation we had was full of character and in traditional Nepali style... read more

We want to thank Kripa for arranging this awesome unforgettable vacation. This goes beyond my expectations. Love the Hotel both the Dwarika's in Kathmandu and the Pavilions in Pokhara. Walking in the streets of Kathmandu is an experience and seeing the UNESCO sites (Pashupatinath, Boudanath, and Swayambunath). Being on the off the beaten path Trekking is also great, with varied terrain, and scenery and scanty tourists. Our guide Suma made our trek interesting who also carried my backpack.... read more

From back home in Australia, our contact Amanda in Kathmandu was fantastic!
She was always readily available to help with all of our, (many) questions along the way. From accommodation and itinerary, to connecting us to a city guide, as well as our amazing trekking guide, Priscilla❤️, we couldn't be happier with all that was offered.
Amanda was professional, courteous and lovely and helped us to enjoy our trip of a lifetime, including playing her part in a secret marriage proposal at the... read more

Another great trip. Erin provided everything we asked for, she was always quick to respond and understodd what we wanted. Her choice of Guide and Sherpa were perfect for the group. We felt well looked after and had an unforgettable trip that was loads of fun. Thank you.
Gokyo Ri Trek · Nepal - Oct 19 - Nov 3, 2019
Erin, the Himalayan Trails staff, our guide Wongchu and the team of porters were all stellar throughout our whole experience - from the 10 month pre-trek planning and prep phase, to the moment we stepped out of the Kathmandu airport and all the way back again to our departure. As pretty well fit 50 year olds we found the Gokyo Ri/Lakes circuit challenging, namely due to the altitude. But the length of the trek and the acclimatization days did seem to help ease the associated symptoms. Some... read more

Our group of seven recently came back from a trek in Nepal through your company and i thought it may be helpful to provide some feedback on our experience. Overall, we had a fantastic time and found all the staff professional, positive, and very attentive. We really appreciated that Erin was able to book not just our trek, but also our kathmandu hotel, our Surkhet hotel, and our internal flight to Surkhet. That was so convenient for us and made our lives much better. Everythimg was taken care... read more

Oooh we really enjoyed it! It was so impressive, such a beautiful landscape and country. The people are really friendly and the food was good. Fortunately we were lucky with the weather so the view was amazing. Tendu was a nice guide, he really took care of us.
The only little negative thing was that the driver didn't find our hotel where we stayed after the trekking tour. So we had to help him with google maps. But it can happen, so we forgot it immediately when we arrived.
You did it again!! · Nepal - Oct 15 - Oct 26, 2019
Hi Erin and the KimKim Team!
Erin you did it again!! Top marks for another incredible trip to Manang.
Your professionalism, friendliness, organistion, attention to detail and providing us with THE best
guides, Raj and Rabin, made for an unforgettable trip. The journey left a profound impression on each of us and will forever stand as a superb adventure in a beautiful country with wonderfully open hearted people.
Dhan'yavāda from us all!

My wife and I booked an 8 day luxury trek around the Everest Area in Nepal with Erin. The travel platform for communication with Erin via KimKim was really easy to use and worked without issues. I found Erin super responsive and exceeded our expectations.
The lodges they utilized were awesome. The Beyul was one of the highlights for my wife and I. The owner is super personable and the dining was great. Another fantastic lodge was the Everest View Lodge in Mende. This lodge is really... read more

O wow... an adventure that far exceeded our expectations! Erin was amazing in our pre-travel planning. I must have asked a million questions that were always answered thoroughly ..I gained such confidence in the team before we had even landed in Kathmandu. All the transfers from pillar to post were punctual, the drivers were super polite, the Kathmandu guides were great ... we were so spoilt! Our trek with Serala as our guide was fantastic. We were very proud to have one of the few woman... read more
Nepal, an adventure and life memory · Nepal - Sep 28 - Oct 7, 2019
Nepal was the second part of our holiday abroad, and it was fantastic. We enjoyed our hotel choices, especially Dwarika in Kathmandu. The helicopter ride to Mount Everest was epic! The views were incredible. Thank you Erin for planning such a memorable adventure.
Kimkim review Nepal · Nepal - Oct 19 - Oct 27, 2019
This was my first time with Kimkim. The platform was easy to use and connect us to Kripa in Nepal who has been great. She arranged everything for us and was extremely helpful. The guides, porters, drivers were sincere, knowledgeable and friendly (if not too friendly, as we prefer guides that are less intrusive ie not having to follow you everywhere including meals). Overall experience was pleasant. Our local specialist Kripa was very attentive and responsive when we need help or... read more

I found KimKim (and Amanda) totally on the ball, professional, and very competent. They responded to emails/questions very promptly and were very attentive to detail. The greeting and meeting in Kathmandu was helpful and the trip itself was excellent and tailored to our needs. Overall very pleased.
Himal Mardi 7 days trek · Nepal - Oct 11 - Oct 20, 2019
The best thing about Himal Mardi trek is the changing terrain from tropical to alpine . Our highlight was reaching the base camp and seeing the closeness of the peaks of Annapurna and Macchapuchare ( Fishtail Mountain) . We had a tremendous guide , Scchapel , who was very informative , very experienced and we got along very well with him . Everything from start to finish was very well organized thanks to Erin . The only setback for me , which probably can’t be helped due to water shortage... read more
Kalinchowk Multi-Sport Adventure - 8 Days · Nepal - Oct 5 - Oct 12, 2019
An absolute trip of a lifetime! Our trip was away from the crowds and as such, there was the odd challenge but would highly recommend getting off the path well trodden. We didn't see a single other tourist for the duration of our trip and hence saw the real Nepal, right up close to the border with Tibet. Staying in tents did require more logistics than tea houses but we did feel much more engaged with the scenery and that blissful feeling of isolation every morning. It also felt more of an... read more
Trip to Nepal · Nepal - Sep 6 - Sep 15, 2019
It was my first trip to Nepal and everything was handled perfectly. Kripa was very helpful and able to give good tips about the trek and the whole office worked to make sure that my experience was great. While the weather could have been more cooperative my guide was able to make adjustments and everything worked out great.
adventure days · Nepal - Sep 10 - Sep 21, 2019
Some more 5 stars for Erin and Himalayan Trails and they are all well-deserved! Very well organized trip that exceeded our expectations. Unfortunately I cannot remember the names of all our guides and it would be unfair to others if I mention only a few. They were all so kind and helpful with good knowledge about each area, history and religion of Nepal. The only bad thing is that we didn't have the chance the see the Himalayan range due to the late monsoon season but I think clearing the... read more
Nar Phu, Tilicho Lake and the Annapurna Circuit · Nepal - Aug 18 - Aug 31, 2019
Our Nar Phu and Manang trek was an unforgettable adventure. Especially the Nar and Phu part of the trek was outstanding with amazing landscapes and breathtaking views, great hikes, incredibly friendly and hospitable people who always had a great smile for us and a deep insight into local culture.
Our guides Mingmar and Dorje were supergreat and a lot of fun and would always offer support when needed. We spontaneously changed the second part of our trek due to my fear of heights, which was... read more
Nepal & Bhutan · Nepal - Apr 2 - May 1, 2019
It was a once in a lifetime trip! Our guide, Nawang, was extremely flexible which was very appreciated because we encountered unusually bad weather which forced us to change our itinerary en route. He was unflappable, upbeat, and listened to us about what we wanted to get the most out of our trip and helped us to meet some of the people we were interested in along the way.
Week Below Everest and Village Visit · Nepal - Jun 19 - Jul 10, 2019
We just completed a 3.5 week vacation in Nepal that included stays in Kathmandu and other cities, tours of heritage sites and a national park and a trek in the Annapurna region.
We have traveled extensively in Europe and elsewhere and have always made our own arrangements, and have done very well. For a trip to Nepal you need professional assistance and we received exemplary service at every stage of our trip.
Before we arrived in Nepal, Amanda helped us with all... read more

It was an amazing experience. My guide Naresh took care of me throughout my trip:)
Everest Base Camp and Gokyo Ri Trek · Nepal - May 22 - Jun 8, 2019
Overall a wonderful trip. I think as a group we were very satisfied with the service provided by Erin and her team. They were easy to contact and made sure that we had everything we needed like rides to and from the airport, information on the trek, and even helped make possible a helicopter trip to Kathmandu which we all really enjoyed.
Some of the highlights of the trip include the helicopter ride to Kathmandu, Kalapattar, EBC in the snow, visiting the Tengbooche monastery, and staying in... read more

Review for Nepal Tibet trip from 18th May – 5th June 2019
Unforgettable Nepal, I was back to this country again for trekking to Lower Mustang,
which is very similar to Tibet Plateau?
First time domestic flight from Kathmandu to Pokhara without delay, leaving me plenty time to explore this town again either food or shopping. Stunning view from plane flying from Pokhara to Jomsom and landed on an “unbelievable” that it’s an airport! Weather changed from hot Pokhara to a dry and cool Mustang,... read more
Langtang Trek - 11 Days · Nepal - May 29 - Jun 9, 2019
We just got back from an amazing adventure in Nepal. We can't thank Kimkim enough for helping to create a magical trip. From start to finish, we couldn't have asked for anything more. Erin, our local specialist, was extremely responsive in arranging all of the details for our time in Nepal, patiently answering my questions and providing a lot of information to help us prepare for the adventure. Raj welcomed us our first night in Nepal, and met with us again on our last day, making sure... read more
Manaslu Group Departure · Nepal - May 18 - Jun 4, 2019
What an incredible experience! Two weeks in the Himalayas was an extremely welcome reconnection with the natural world. Walking through villages, seeing how local people live and experiencing the incredible wildlife there was a very unique way to travel the country. My guide Priscilla was excellent - very passionate about her country and her job. She was an experienced guide, a hilarious companion and a truly kind friend. I can't recommend her enough, and it's always great to support female... read more
Group departure - Manaslu Circuit Trek: Group Departures - 15 Days · Nepal - May 3 - May 22, 2019
Trekking Manaslu was a wonderful experience, beautiful scenery, people, and the rustic charm of the villages made every step of this challenging trek worthwhile. The planning was impeccable, thankyou Erin. Our guide Nawang was very experienced, professional and patient, as well as being good company. The support from Ngima was fantastic, hard working and always smiling. I highly recommend this trek and the team that made it possible
Ghandruk Trek - 3-4 Days · Nepal - May 19 - May 24, 2019
My guide was Rishi and he did a really nice job of supporting me throughout the trek as I am not terribly athletic. It was a really lovely experience. The driver was very helpful and patient as well.
Anapurna circuit · Nepal - May 3 - May 20, 2019
My experience in Nepal was simply superb! I met a number of great people along the way including my trekking guides and porters as well as other local guides and and touring specialists.
The trek around the Manaslu circuit was simply breathtaking with incredible views and a moderate amount of physical exertion it was the best trekking experience I could have asked for.
Additionally my sight seeing tours in Kathmandu were fantastic and i managed to see an incredible 5 out of 7 UNESCO... read more

Pikey Peak · Nepal - Apr 7 - Apr 15, 2019
This was Pikey (Peekay) Peak trek We enjoyed this trek and the trip. The trail overall was a bit more off the beaten track with fewer other trekkers hogging the showers, the stove and the views - which was what we wanted. First two days uphill were harder work and weather. But we were rewarded with perfect clear skys for the views from Pikey Peak 1 & 2 (do both) which were fabulous. Actually enjoyed the trail back down more than the up, which is unusual. May have been the weather. Check out... read more
Khopra Trek Package · Nepal - Apr 18 - Apr 27, 2019
Mindu, bacenta and our porters were so helpful and lovely for our hike! We definitely would recommend using Kim Kim, Amanda and our guides in Nepal to other friends and family. Thanks again for helping organize this trip for us as we were all so time poor in the lead up. Big thanks to Amanda for always answering our questions quickly and seeing us pre and post hike! It was a nice touch that we all appreciated!
Exploring nature with both adventures and relaxing accomodations · Nepal - Apr 21 - May 4, 2019
My husband and I were excited when we made the decision to travel to Nepal for a trek and to explore the country, however, were having difficulty in figuring out the logistics on our own. We were so fortunate to connect with Kripa through KimKim.
We highly recommend working with Kripa. During the planning process, she answered all of our questions in a timely manner and was friendly/professional/helpful. She gave us all of the information we could possibly need to prepare for our travels.... read more
Weeklong trip/trek in Nepal · Nepal - Mar 29 - Apr 6, 2019
Amazing trip to Nepal: the Muldai + Poon Hill trek was an excellent choice for our group (3 adults + 4 children, ages 10-14): it offers breathtaking views of the Annapurna range; a good balance between trekking difficulty to relax/chill-at-the-teahouse time; a variety of trail sceneries: sunny mountain crests with long vistas; lush river valleys; occasional patches of snow; small villages; tiny teahouses and spectacular views from Poon Hill (Muldai was cloudy, but worth the early wakeup and... read more

Our guide Sonam was absolutely exceptional and made our trip. She was always extremely professional, helpful and would always know how to make us smile in times of hardship. When I undoubtedly return to Nepal I hope I am paired with... read more
Manaslu Circuit · Nepal - Apr 20 - May 6, 2019
In my opinion Priscilla was different from the other guides because unlike others where they try to set an itinerary up the mountain, she keeps her options open by deciding based on my capabilities and is very attentive to my wellbeing and gives the impression that I can trust her. She also shared with me the local culture, way of life, and a wealth of knowledge on native plants. This effectively made my trip up in the mountains an enjoyable experience, not just a trek through the pass. She... read more
Pikey Peak Trek · Nepal - Apr 23 - May 2, 2019
We had a great experience from planning our trek with Kripa through to leaving Nepal after 10 unforgettable days. Our guide Tendu and porter Gulu were exceptional and passionate about trekking especially through their home region of Nepal. Great trek which was quiet and spectacular.
