Hidden Forest Cave

It is in Oregon's Deschutes National Forest, in the Central Oregon lava-tube region near Arnold Ice Cave. The surrounding landscape belongs to the volcanic terrain associated with the Deschutes area.

Its distinctive feature is the sub-alpine forest flora near the entrance, where a cool lava-tube microclimate supports plants that stand out from the surrounding forest. The name points to that forested entrance, not to a cave filled with trees.

It is a rugged lava tube with deep pits, so it should not be treated like a lit commercial cave. Route finding, reliable lights, helmets, and careful footing matter more here than on a normal hiking trail.

No. They are separate named caves in Deschutes National Forest, although they are close enough to appear in the same local cave area. Hidden Forest is known for deep pits and its sub-alpine entrance flora, while Arnold Ice Cave is a different lava tube.
