In reply to Joel Perkin:
Some 8h drive from Krasnoyarsk, there's the Ergaki National Park with some stellar looking granite (?) spires. There's a guidebook for the place (there is one for Stolby as well).
There's also a new (2021) guidebook for Lake Baikal area as well. Looks like nice, granite, alpine routes (+ mixed stuff as well).
There's a nice looking wall called Mt. Fisht in the Caucasus.
There are quite a few developed single pitch crags but those never interested me.
Never climbed at any of those but have made a trip to the Russian Far East; a place called Bilibino in Chukotka Okrug (w. very limited climbing successes). You can google around & find write ups of the previous 4 expeditions to the place (incl. a British one). Special entry permits required for this one.
