Wat Tham Mangkon Thong is a temple a little outside of Kanchanaburi city known for its floating nun.It is a real nun who practices a ritual ending up entering a small pool and floating there. There are bleachers around and to attend this ritual you surprisingly have to pay and not just make a donation at the end (see the price below). On week days, except when there are groups, the nun only floats if you pay for a private show. It is on Sunday that you are most likely to see it without paying the high price. Everyone will have their own opinion about this but as I visited the temple on a Wednesday, I chose not to pay for a private show and went to the staircase leading to the temple cave. Inside, the first room houses several statues of venerated monks, then you arrive at a branch with on the left a small room with the statue of a hermit and on the right a passage which obliges you quickly to walk on 4 legs before arriving at a ladder going outside and there ... you arrive in front of 3 statues easily accessible from the outside but if you like to crawl in caves in an adventurer mode, it can be fun to do.
