Pha Kluai Mai Campground – Haew Suwat Waterfall

This nature trail links two waterfalls, following Lam Ta Khong stream and alternating between bamboo forest and dry forest at intervals. Along the trail you will hear the thundering sound of Pha Kluay Mai Waterfall during the rainy season. However, when water levels drop in the dry season, you can see the traces of lava flow from a volcano hundreds of millions of years ago. Also there are Polypleurum flowers, a newly reported species, sprouting between the rocks, along with Renanthera orchids (“Whai Daeng”), which give the waterfall its name from the white and red blooms appearing around the waterfall during April.

Many species of animal can be found near the water course such as butterflies, water dragons and otters, with groups of gibbons in the trees, hornbills and hawks foraging for food. At the end of the trial are rock platforms in the stream which are only visible during the dry season.

Guess which animal made these tracks?

While trekking a nature trail, you shouldn’t miss looking for animal tracks of the resident fauna. It is an activity of discovery, even if we don’t see the animal directly, and coming across the bigger animals is rare indeed. In actual fact, we are the strange object to the animals, and their instincts are naturally cautious. They generally conceal themselves, leaving only their tracks for us to decode.
