There are several frozen waterfalls in the Korouoma area suitable for climbing. The best-known ones include the 60-metre Ruskeavirta and Mammutti, the latter of which is favoured by beginners. The number and formation of the frozen waterfalls suitable for ice climbing vary from year to year, and depends on rainfall and frost.

The most popular route to the frozen waterfalls is the trail starting from the Saukkovaara parking area. Ruskeavirta can be seen on the opposing side when descending to the canyon from the parking area.

Ice climbing is allowed at all waterfalls in the area. Due to the inherent risks in ice climbing, beginners are advised to complete an ice climbing course organized by a climbing association or a commercial organizayion before trying it in the wild. Climbing associations operating near Korouoma include Koillismaan Kiipeilyseura (facebook.com, in Finnish) in Kuusamo and Rovaniemen Vuoristoklubi (rovaniemenvuoristoklubi.com).

Cliff climbing in the Korouoma area is restricted to the cliffs at the western end of the canyon. More information about the area's routes is available from e.g. Suomen kalliokiipeilyreitit (Cliff Climbing Routes in Finland), published by the Finnish Climbing Association.
