Hi,

The TF Khao Yai info is here (updated about 10 months ago now):

And here:

And Pak Chong is here:

However while doing that research I didn't find a really good topographical map of the park other than a few big ones on the walls of hotels and guesthouses, although even those didn't look entirely reliable. The work linked to above is more of a rough guide on how to approach the park and what to expect, not a serious guide on hiking the remote regions of the park. I do know that park officials definitely don't encourage people to set off on long hikes into those areas by themselves. If you ask at the visitor center, they'll tell you to arrange for a park ranger to accompany you, which will cost a bit of cash but is certainly an option for doing some serious trekking. I personally did not do any overnight hikes on the more remote trails.

This is the best other site I've come across for info on the park, although it doesn't offer any maps you won't find at the park:

Unfortunately Khao Yai is still a relatively tough nut to crack for independent travelers, serious outdoorspeople or otherwise. My best advice if you're really a well-trained outdoorsperson with experience trekking independently in this part of the world would be to just go there and see what you can manage.

Whatever the case, do come back and tell us how it all goes.
