Siena Mueller

Whether you're a solo adventurer, a couple seeking romance, or a family craving new adventures, I'm here to tailor-make your journey, ensuring it surpasses your expectations while contributing positively to the local community. From scenic nature activities to deep dives into history, culture, and cuisine, I'm passionate about sharing my love for travel with all types of adventurers.

What places and activities do you specialize in?

"I specialize in crafting tailored trip plans for solo travelers, couples, and families, catering to newcomers and experienced travelers looking for a new adventure. My favorite activities include scenic nature adventures and immersive experiences in history, culture, and cuisine."

How did you get involved in travel?

"Guided by my family's adventurous spirit, my introduction to travel began at an early age. My mom prioritized taking my sister and me on yearly trips to new places throughout my childhood, from local road trips to flights across seas. These experiences sparked my love for exploration, paving the way for my pursuit of a Bachelor's Degree in Sustainable Tourism Development. During a study abroad program in Greece, focused on community development and tourism in the Mani peninsula, I fell in love with the country's rich culture and gorgeous landscape. With 20 countries under my belt, each journey adding to my wealth of experiences, I continue to be inspired by the transformative power of travel."

Please share a unique travel experience you will never forget.

"I have been so lucky to have had many impactful travel experiences - my pro tip is to keep a travel journal to help you remember the details of your adventures! One particular adventure stands out: a hike from Milia to the Panagia Giatrissa Monastery. Trekking through lush green mountains, we discovered hidden creeks and funky insects. We finally reached the top, after getting beautifully lost for an additional mile or so, and soaked in the inspiring view of the mountain range. There, a clergy member shared the land’s deep-rooted history over Turkish coffee. Returning to Milia, we shared a meal with locals, tasting some of the finest olive oil and exchanging stories that bridged generations. This experience perfectly encapsulates my approach to travel: a harmonious blend of nature exploration and cultural immersion, connecting with locals who enrich our understanding of the places we visit."

I especially appreciated the pre-trip Zoom meeting, where Siena walked us through the itinerary, highlighted important details, and shared so many helpful recommendations and tips. Because of her expertise, I’ve already recommended KimKim to several friends who’ve asked about our trip, and I know I’ll be a returning client for future adventures.

our trip to Australia went very well, with a couple of administrative problems. The pickup locations were sometimes wrong or contradictory. I opted out of Kata Juta but my sister marian was removed instead. our booking for the wine wildlife waterfall tour in sydney was made in gregs name, not us. But overall the excursions, tours, boat trips were very good. Hotels were fine. Car pickups all good.

NLH Fix Hotel - Neighborhood Lifestyle Hotels

This hotel was very basic, but our room was HUGE, which was very helpful for our family of 4. Excellent location, right near the Acropolis and Acropolis Museum. Walkable to tons of restaurants and cafes. One thing to note: the hotel has no lobby and has only a very tiny elevator. As there is no common space, overseas travelers will need to find someplace to rest while waiting for an afternoon check in.

Delos was incredibly interesting— it’s an active archeological site. However, I wouldn’t recommend this for small children or for anyone who can’t be in the sun for several hours. It was super enjoyable but exhausting and very hot. Our guide Christos knew SO much and so loved listening to his explanations and especially loved sitting at the Greek theater! Mykonos felt short— just enough time to grab lunch and do some shopping. Perfect for someone who wants to just get a sampling of the island but not enough to really experience it.
