Thing to Do

Hike the North Crater Trail

A hiker with a large backpack walks on a cinder trail toward a large volcanic cone.
The North Crater Trail follows the rim of the crater and drops into its mouth.

Trail length: 3.5 miles (5.6 km) round-trip
Elevation gain: 758 ft (231 m)

The trail traverses North Crater and drops into the crater mouth, the vent for the North Crater flow. The trail continues to the rim of Big Craters before descending to the Spatter Cones. In order to protect fragile lava formations, off-trail travel is not permitted in the Big Craters area.

Start your hike at either end of the trail. The northern trailhead is located just a few hundred feet up the park road from the adjacent North Crater Flow Trailhead, and the southern trailhead is located at the Spatter Cones parking area, branching off from the Snow Cone walkway. Hike out and back, or arrange to be picked up or dropped off at one end for a shorter trip.
