The caves of the district (over 30) are of great interest among tourists.
One can find there a great number of small caves (Tavdin, Proletarskaya, Kyrkrlinskaya,
Tohurakskaya, Katorzhnaya caves and others) and a few ca-ves that are considered
the largest in Altai and East Siberia. Expert speleolo-gists take great interest
in the Shakhta Altaiskaya (Altai Mine) - the largest and deepest cave of Altai
and East Siberia situated in the upper reach of the Ustyuba river. It's 240
m deep and 2.5 km long with a great number of pits and passages. Stalactites
and stalagmites form fascinating 5-meter pillars, while calcitic “flowers"
amazingly set off the lakes inside the underground chambers. The caves are especially
impressive in winter time. Enchanted world with no sunlight...
