Thukje Monastery

A hot spring popular with locals and foreigners alike. There is a commercial resort nearby, but also an inconspicuous building with three doors where you can bath for free—wait for one room to become available and plug the hole of the inner pool to let the water flow in and gather.

An interesting valley with several geysers, hot springs and (alleged) mud volcanoes. Go for sunset when the area offers impressive pictures. You may also try to dip into the river that crosses the valley when it leaves the hot spring area—it becomes quite warm at last.
