Arnold Ice Cave Trail runs from Horse Butte trailhead all the way out to Swamp Wells Horse Camp.
Bunch grass, sagebrush and hidden rocks make for a narrow tread — with the trail getting more remote as you get farther from Horse Butte. The trail starts in the tree cover, and ends in tree cover — but the vast majority of the trail has open views all around. There are some rocky bits along the way with the most challenging portion being a short switchback climb up a ridge just before mile 3.
The second intersection is with Horse to Horse which will take you out to the Horse Ridge riding area. From this intersection the trail has no other intersections until you reach the Horse Camp. From the camp you have the option of heading back to Horse Butte by way of Coyote Loop, or Swamp Wells.
For a special treat – Arnold Ice Cave and Hidden Forest Cave are very close to the where Arnold Ice Cave trail crosses China Hat Road.
This trail is maintained by Central Oregon Trail Alliance.
