Small Heaven Lake

Grab a bus from the Changbai Waterfall to Small Heaven Lake. Nowhere near the size or majesty of the main crater lake, this is instead a placid lake (or large pond) worth circling. You could venture off into the surrounding forests for a short hike, but don't get lost and be careful not to cross into North Korea! A boardwalk takes you along a fissure stream to the Green Deep Pool.
