The sculpted landscape of Smith Rock State Park began over 30 million years ago.

explore Crooked River reflections of Smith Rock State ParkThe Crooked River Caldera was created by the sudden collapse of overlying rock into an underground reservoir of molten rock.

Massive amounts of ash and debris from the resulting eruptions then filled the caldera and hardened into rock.

Smith Rock Tuff–the largest rock formation on the western rim was the outcome.

Flows of basalt lava then poured into the area over half a million years ago from vents almost 50 miles away, creating the cap on the tuff in the caldera.

The result? The mini Grand Canyon you see today.

With over 650 acres to explore  you can spend days here and experience something new each time.  Add the northeast link to BLM/USFS land, and your stay just got longer.

Check out our detailed trail system section to start your exploration and link to virtual tours of each of the trails.

Need a park brochure to get an overview? Here you go.

Come rig your slackline, jump on any of the hundreds of climbing routes, hike along  the scenic River Trail, or challenge yourself to bike, or run up the Summit Trail loop back to the river.

Staying at the Cyrus Horse Camp? Come over the Gray Butte Trail and down the Burma Road into the park. There’s something for everyone.
