A network of local village trails and established teahouse trekking routes provide for a variety of custom itineraries, from the classic Ghorepani / Poon Hill trek to the less-beaten paths that lead to Khopra Danda (and beyond!). Below are few great options that can all be customized to match your preferred number of days and difficutly.
There are various routes to access the great vantage points and villages of this region, all which can be tailored to fit your desired pace and duration. Most routes start with a jeep or bus ride from Pokhara to Nayapul, where you'll start your trek.

You'll stay at a single teahouse perched atop the ridge with 360 degree views of the Himalaya massifs that come to light at sunrise and sunset. (A new teahouse is currently being built and expected to be completed by 2018.)

In a short amount of time, you can acces three great vantages points which are normally only reached after numerous days of trekking and proper acclimitization - Poon hill (3200m), Khopra Danda (3600m), and Muldi Peak (3647m) - all of which offer panoramic views of Dhaulagiri, Nilgiri, Annapurna South, Annapurna I, and Macchupucharre (the last can be seen only from Muldi Peak).
Trekking anywhere in Nepal poses a challenge given the often steep climbs to reach vantage points and the altitude. Generally, however, treks in the lower Annapurna region offer a mix of both easy and moderate trekking, given the lower elevation compared to other treks.
Knowing The Seasons
Spring - March to May
The second best time to trek, given it's a bit warmer than the fall but still a good chance of clear skies.
Monsoon - June to September
The heavy monsoon rain starts in June and continues (around one per day) until early September. Generally, not the best time for trekking given the heat and leaches in the jungle.
Fall - September to December
It starts to get clear in mid-September and the temperature is great for trekking. Be sure to bring a little more extra clothing for the cold and windy weather.
Winter - December to February
You'll still have great views, but will have the cold nights, chance of snowy weather, and some slippery patches of trail to contend with.
You'll need to arrange a TIMS and ACAP permit from one of the Nepal Tourism Board offices in either Kathmandu or Pokhara. There are checkposts along the way where you'll need to display these permits and log your name, both for safety and to help monitor activity on the trails. If you organize your trek through an agency, they will arrange these permits for you.
