The caravanserai of Tash Rabat is a restored (reconstructed) building out by itself miles from anywhere. It is an opportunity to see what the stations along the Silk Route were like.
Right in front of the caravanserai are 2 yurt camps. We stayed in the closer of the 2 to the caravanserai - the owner is the said Nazira referred to in another post here. The yurts are fine, and food was served in the building attached to their house. Fairly standard and adequate Central Asian cuisine.
We rented horses and a guide from the yurt owners for an 8 hour trek up to the top of the Torugart Pass. I think it is about 7800 meters high and has views over the lake below and the Chinese frontier beyond - the wind fairly whistles through the pass, which is saddle shaped, and it is cold, cold there, but worth the ride. The ride down is scarier than going up,but the horse are used to it and are sure footed.
Some of our friends, who were experience mountain walkers, reached the top and back in about 10 hours.
The toilets are not unexpectedly of the "long drop" variety - there is really no alternative here!
To appreciate the Silk Route and the conditions that merchants of old endured, you really want to visit this site and stay overnight
