Redmond Caves

The Redmond Caves are a group of six lava tubes in Deschutes County, Oregon, United States. The caves are located in the city of Redmond and are jointly managed by the city and the Bureau of Land Management (BLM). Five of the caves are in the Redmond Caves Park and have been known locally for over 100 years. The caves are part of the Horse Lava Tube System and the farthest northern extent of the system. The lava flow that created both the Horse system and the Redmond Caves continued into the Redmond Dry Canyon and terminated near Crooked River Ranch. The caves have a geologic age of about 80,000 years.
