Travel trailers and large RVs are not recommended beyond Grayback campground (mile post 12) due to the winding road to the monument.
Park your RV or Travel Trailer
If you have a large RV or travel trailer, they must be parked (free) at the Illinois Valley Visitor Center (IVVC) in Cave Junction which is located on Hwy 46 at 201 Caves Highway, Cave Junction, OR 97523. This is just a short distance from Hwy 199 intersection in Cave Junction. Call (541) 592-4076 for more information.
There are also two campgrounds located on Highway 46 that will accommodate recreational vehicles and trailers overnight. These are Country Hills Resort (privately owned) and Grayback Campground (National Forest campground), both located on Highway 46.
Did You Know?
The stream that comes out of the entrance of the cave is a tributary to a watershed that empties into the Pacific Ocean. There are no human-made obstructions that would prevent salmon migration, which makes this the only cave in the National Park Service with an unobstructed link to the ocean.
