About Thi Lo Su Waterfall
Thi Lo Su is claimed to be the largest and highest waterfall in Thailand, at around 250 meters high and nearly 450 meters wide. It's never been properly surveyed, so treat those numbers as rough. The falls are in the Umphang Wildlife Sanctuary in Tak province. Private vehicles can't drive to the campsite anymore, so park in Umphang and take one of the local pickups.
