indian himalaya, i spent some time in the parvatti valley, there are bits and bobs up there, but there is much more on a plateau accessible above rishikesh near gangotri i think (issue of friction with details, ill have a look for it) - time of year dependant tho, may be masses of snow! there was also a link to a site of some crazy guy from the lakes who seemed to be living out there HOUDINI!!!! i am sure was involved in that discussion.
thailand - houdini (again) knows the whearabouts of a load of sandstone boulders in central thailand, and they look good from the pics. i have a copy of the tao guide that i feel i should pass on if you want/houdini doesnt want it back (chances of me going again soon are slim). nick the hobbit from buk spent quite a long time climbing in northern tailand near to chang mai.
cambodia - loads there, but i didnt do owt, watch out for those land mines word!
