In the vicinity of Thong Sala, an easy excursion can be made to the grandiosely termed Than Sadet-Pha Ngan Island National Park, which contains Pang waterfall, Pha Ngan’s biggest drop, and a stunning viewpoint overlooking the south and west of the island. The park lies 4km northeast of Thong Sala off the road to Chaloaklam – if you don’t have a bike, take a Chaloaklam bound songthaew as far as Ban Madeuawaan, and then it’s a one-kilometer signposted walk east. A roughly circular trail has been laid out through the park, as mapped out by the signboard in the car park. The main fall – bouncing down in stages over the hard, grey stone – is a steep 250m walk up a forest path. The trail then continues for over 1km upriver beyond the falls, before skirting through thick rainforest to the viewpoint and back to the car park in a couple of hours.
