I was merely a follower in a friend’s planned hike to Annapurna Base Camp, so I cannot comment on the logistics when planning with Third Eye, however from their personal accounts, everything went smoothly.
On the hiking side of things, (from Nayapul, up to Annapurna Base Camp and back down) I highly recommend my guide and friend, Ramji. Him and the other 3 porters (each group gets 1 porter per every 2 hikers), were very friendly, answered all of our questions and safely guided us throughout the entire hike. The views all along the hike were spectacular as long as it does not rain. Overall though, I again highly recommend going with Third Eye, and many thanks to them for this unforgettable journey!
