Goh-Ay Mountain The destination here is a river that’s great for a swim. Definitely for the dry season if you want to be a bit more adventurous and see more of the area. Your best bet is to talk to the guys’ at the English school next to the Hotel Sang Phi Run if you want to venture out this way, as they can help with direction or take you out there. Definitely stay on the worn trails by the river area. There are landmines around.
