South Ice Cave is a lava tube located in Deschutes National Forest, which may be freely visited. It is not developed but not very difficult to visit. Bring appropriate clothes, especially warm, sturdy boots, a helmet if available and enough lamps.

The cave includes a small ice pond and ends at an ice plug, hence the name Ice cave. The cold air in winter flows down into the cave and gets trapped there, so the cave is rather cold all the year. However, spring is the best time to see ice formations, as melting water from the surface flows into the still very cold cave and freezes there.
