Tat Saloei

This impressive series of cascades forms a combined drop of almost 100m. It's briefly visible from eastbound Rte 6 roughly 1km after Km 55 (ie 36km from Sam Neua), but easy to miss westbound. There are some small local cafes and restaurants on the roadside here, plus what looks like a ticket booth, although no one was charging for entry at the time of writing.
