I was originally looking for just a food tour of Bagan, and stumbled across Three Treasures. I booked a day long photography and walking tour, which turned out to be one of the most amazing tourism experiences I've ever had! Ian was very responsive beforehand to make sure and tailor my tour to see/do exactly what I wanted, and was flexible for detours on the day of. We ended up going for both sunrise and sunset, as well as taking a very nice walk through a small nearby village and meeting the locals and observing their daily life. He took me to some of the more special pagodas and temples, with unique exterior architecture and interior paintings. He also goes through a lot of effort to ensure the people we came across or helped during the tour were fairly treated and well compensated. Truly, sustainable tourism at its finest.
All in all, it was literally EVERYTHING I ever wanted out of a tour.
