Kyrgyzstan is a place I'd love to see.
The highest peak is Pik Pobedy, which is somewhere in the neighborhood of 24k feet I believe. Bishkek, Osh or Karakol-- on the lake Ysyk-Kol-- are probably going to be your first stop. You may want to check out the foreign entry requirements for Kyrgyzstan (and anyplace else) at http://travel.state.gov
. Have fun.
