Khao Yai - Huai Suwat to the Park HQ -
Do not attempt without a guide
This trail took us by surprise, we lost it many times and found it very hard to follow in sections, requiring a lot of back tracking and marker searching, and as a result I would not recommend it without a guide. We did it using an old map and following the trail markers, with a GPS to back track if anything went wrong or we lost the trail. Why do I say it requires a guide (?):
1) The trail
constantly splits and concats throughout its length
2) There are a lot of fallen trees on the trail removing sections of the trail completely
3) Some animal tracks in the area are bigger than the trail and it easy to take a wrong turn
4) Theres a lot of new growth making some sections very difficult to stay on trail
On top of that I would not recommend it in the wet either because it was tough going with a lot of stream crossings and muddy rises and decents - getting caught in a down pour could delay you at least 2 hours or so and make the trail too long, in terms of time, for a day hike. You would risk spending the night on the trail.
If you do decide to try it, then 1) take a guide who knows the trail 2) take a gps 3) notify the park officials of your itinerary 4) set off
early in the morning so you have time if anything goes wrong.
What will you experience - true mixed evergreen forest, leeches, ticks, humidity off the scale - a true jungle experience! With a guide to negate the chances of getting lost this is a great trail.
