Pokhara is the second largest city in Nepal with about 400,000 people in 2018. It is the starting point for most of the treks in the Annapurna area. It is a very popular location with most people staying around the beautiful Fewa Lake. Dozens of hotels and restaurants are sprouting like mushrooms everywhere, and today it is much easier to find modern amenities not common to other locations in Nepal, but Pokhara is losing its small town charm and the lakeside now feels more like Khao San Road (with all the usual: yoga, reiki, massages by blind people, overpriced souvenirs and disingenuous locals).
Pokhara is still beautiful and many great and genuine people can be found, but it takes some work on the traveler's side. If you intend to stay on the lakeside road, para-glide, and trek to Annapurna, you will be getting a very inauthentic version of Nepal. If you make an effort to get out of the tourist areas, you will find amazing scenery, great people, and unforgettable experiences.
