Ilya Muromets (Илья Муромец), named after the East Slavic folk hero, is a very steep vertical waterfall on the Bear's Peninsula of Iturup, one of the largest Kuril Islands.

Iturup has been the subject of a territorial dispute between Russia and Japan and also has a Japanese name, Rakkibetsu Waterfall (ラッキベツの滝).

The water stream falls abruptly from the eastern slope of the Demon Volcano into the Pacific Ocean.

[2] Ilya Muromets is rarely seen by tourists, however, because it can be accessed only by boat.
