Old Gushie Cavern is a tourist attraction featuring Old Gushie, the first volcano ever to erupt on schedule like a geyser.
The cavern is mostly gray and brown. Some of its caves are comprised of slip-rock and Spillio Bacteria. There are many rocks, cliffs, and ledges around the area. Several ledges are surrounded by metal fences. A mine railway is located within the cavern.
Old Gushie Cavern has appeared in one episode of The Backyardigans: "Super Team Awesome!" from season four.
