Deep in the heart of the Siskiyou Mountains lie the wonderful Marble Halls of Oregon, carved out of the solid marble by centuries of rainwater. You can tour the labyrinth of passages, chambers, and pathways on a 90-minute guided Discovery Cave Tour, where you can learn all about the geology of the cave system.

For the more adventurous, there is a three-hour Off-Trail Adventure Tour in summer, where you have the opportunity to belly-crawl, climb and slither through some very small spaces. To get really close to nature, you can pitch your tent in the campground and spend some time exploring the several scenic hiking trails.
