Back when the Santiam Wagon Road was in use (between 1865 and 1939), House Rock offered temporary shelter during storms. This massive stone forms a natural cave. Giant old growth trees surround this interesting spot on the old wagon road. Definitely worth taking some time to check it out.

The short jaunt to Boyd Cave is worth your time - you can explore just the small chamber at the foot of the stairs, or bring headlamps and flashlights to check out the nearly 1880 feet of lava tube cave that stretches out from the access point.

The Oregon Caves Visitor Center is open from spring through fall. It offers cave tour ticket sales, information, exhibits on the Oregon Caves and Siskiyou Mountains, Junior Ranger programs, and a bookstore. Visitors can access several popular hiking trails from here, including the Cliff Nature Trail and Big Tree Trail. The visitor center is also where you meet for guided cave tours. The caves are only accessible if you are a part of a guided tour with a ranger (please visit https://www.nps.gov/orca/planyourvisit/cave-tours.htm for more information on the cave tours). Due to high demand in summer, it is recommended to check current conditions and purchase tickets at the Illinois Valley Visitor Center, which is located in Cave Junction at the bottom of Cave Highway.

This is one of many lava caves that exist in the volcanic landscape of Central Oregon. The entrance is very narrow, leading to a small chamber and another narrow and steep hole to get deeper into the cave. Bring a headlamp or flashlight and don’t go alone!

In the early spring, the rushing waters of the Rogue River may obscure the features of Natural Bridge - where the waters briefly dip underground as they roar through a lava tube. The gate remains closed until early spring; you may have to hike in from the road if this is the case.

Crack in the Ground is a stunning geological feature within Four Craters Lava Bed Wilderness Study Area. The volcanic fissure is two miles long and up to 70 feet deep. You can take a hike into this gorge. Keep an eye on the weather, though, and avoid it during rain since it might get flooded in a rain storm. It is just a short detour if you take the Christmas Valley alternate of the Oregon Desert Trail.

You can find Boca Cave by taking a short spur trail near the summit of Triangulation Peak. The cave offers some pretty cool views from the entrance and is actually a pretty wide shelter in itself once you start walking through it. If you've already gone up the slopes of Triangulation Peak, this is worth a visit.
