Mount St. Helens South: Forest Roads 83 & 81

Area Status: Open

Forest Road 83: This nine-mile, paved road passes through forests, over 2,000 year-old lava flows and across a mudflow created during the 1980 eruption.

From Forest Road 8303, a spur road, visit Trail of Two Forests Interpretive Site or Ape Cave. Continuing driving on 83 to access June Lake Trail, Lahar Viewpoint (the only clear view of the mountain’s south side from the road), Ape Canyon Trail and Lava Canyon Interpretive Site.

Forest Road 81: This mostly paved but several miles of gravel, rough road transports you through less traveled parts of the Monument. Spur Road 830 ends at Climber’s Bivouac Trailhead, the start of the summer climbing route. The road winds west to Red Rock Pass, Blue Lake Trailhead, and Kalama Horse Camp Campground, eventually connecting back with Highway 503.
