Located 16 miles away of Prineville, Eagle Rock is a striking ash-flow tuff formation that resembles an eagle perched high above the landscape. Visible from Highway 380, it serves as a landmark for turning onto the gravel and dirt road leading uphill to the trailhead.

This scenic area, known for its striking volcanic formations and diverse geology, lies within the boundary of the Ochoco National Forest and is managed by Bureau of Land Management. Notably, 150 acres of land here have been set up for recreational rockhounding.

Exploring Eagle Rock: Hiking

The Eagle Rock trail is a challenging 0.7-mile hike (one way) with a 500-foot elevation gain. While the trail is well-maintained, expect steep, slippery, and rocky sections. Good physical condition is essential for tackling the sheer slope to the top, and sturdy footwear and hiking poles are highly recommended. Wet ground or hot weather can make this hike particularly difficult, so bring plenty of water to stay hydrated.

The effort is well worth it. The rugged terrain, framed by juniper-dotted hills and dramatic basalt cliffs, culminates in breathtaking vistas at the summit.

If you're both a hiker and an avid rock collector, this area offers double rewards—you may discover collectible rocks as you reach colorful basalt cliffs.

Eagle Rock Rockhounding

Designated by the Bureau of Land Management as a recreational rockhounding site, Eagle Rock is featured on the Central Oregon Rockhounding Map, available for purchase.

This area is well-known for its brown and black plume agate, as well as moss and botryoidal agate. Brightly colored jasper in red, yellow, and orange hues is often scattered across the surface.

Collecting at Eagle Rock can be challenging. Surface collecting yields limited quality material. The best specimens are often embedded in the cliff face, and removing them can be very difficult.

If you decide to break minerals from the cliff face, wear gloves and safety glasses to protect yourself.

Be cautious of unstable cliff sections and move to a safer spot if needed.

Spring and fall are the best times for visiting, with cooler temperatures making exploration more comfortable. After winter rains, seasonal streams often expose fresh deposits, making the area particularly rewarding.
