Beautiful waterfall hidden in the mountains, near the old high school ruins near Tafunsak. Once you pass by the school, you can park and head on the trail towards the mountains, past an abandoned blue building on your left. There are no signs leading there, and it is on private property, so ask a local for assistance. There was an attempt to make this a tourist spot, but it wasn't fully completed, and now the hut and rocks are starting to degrade. Still worth the short hike from the road. Location on map is approximate. If you're adventurous, you can climb the banyan tree on the right side of the waterfall all the way to the top, to have a better view.
"Didn't think this trail would be much, but we were pleasantly surprised! It took about 20-30 minutes, and the views are magnificent at the end. Nice waterfall, volcanic rocks, huge waves and great views of the island."
