The Kadrin is a medium size right tributary of Katun, the major river of the Altai; it is almost-never-run river mostly because of terrific access to the put-in.
The river starts on an uninhabited plateau between Katun and Teletskoye Lake and generally flows west all the way to Katun confluence. The Kadrin has several class 4 gorges (with some definite class 5 rapids), separated by long easy sections. Reportedly, the river contains a 12 m waterfall, but there is no information whether it is runnable or not.
A weird thing about the river that everyone notices its volume apparently slightly decreases by the confluence; possibly because of water leakage into some underground caverns. Time to think and be cautious about undercuts...
Access & Logistics
Apart from hiring a helicopter, any other way to the put-in is highly arduous; this area is equally distant from any road to the east, west, north, and south.
Two groups that reportedly have been on this river were trekking from middle Bashkaus (east) and middle Sumulta (north) valleys correspondingly, but neither way seems to be optimal. Both treks involve crossing several passes with significant altitude gain and drop and it took them 5 to 6 days to get there.
According to local sources the best way to the upper Kadrin is from the south, starting halfway at the Aktash - Ulagan road (see Bashkaus description for details). Theoretically you can try to hire horses in Ulagan or nearby settlements. A large shepherd’s trail goes north along the plateau, avoiding major climbing and descents. Overall trek distance is about 50-60 km (30-35 miles) and should be possible in 3-4 days. Nobody has undertaken this trek though.
There’s no road on the Katun river at the Kadrin confluence, and you will have to proceed down the Katun to the nearest village (Kuyus, Elanda or Chemal, 1-2 days, see Katun description for details).
The entire trip must be planned completely self-supported; there are no settlements along the way. Reportedly there is a hunting resort with a helipad on the middle Kadrin, but there’s no guarantee it will exist when you come there.
Emergency escape from the river most likely has to be hiking along the river down to Katun confluence, because all gorges are relatively short and valley is quite open most of the time. The Chuya Road comes to the left bank of the Katun about 10 km above Kadrin confluence; therefore you would have to cross the Katun somehow to access the road.
