We hiked the classic Annapurna circuit for 18 days with our guides Deepak Dhakal & Shanker, and porters Raju and Bishal, and it was awesome. We booked as a couple and were grouped with 2 solo travelers. Great group; we played a lot of Nepali card games with the 8 of us in the evenings, while other guides seemed less social. During the day, our guiding duo provided us with ample information and some free entertainment as well. They also kept an eye on altitude symptoms, taking over a backpack on the pass for someone.
Overall, NHT is not the cheapest, but we stayed in nicer guesthouses, airport pickup and all food were included, the guides spoke good English, they transported our luggage to Pokhara without an extra fee, so in the end, it was good value for money. All communication upfront was effective (e.g., booking some extra nights in Pokhara upfront). Would 100% use them again when coming back to Nepal.
