Paved, but rough in places, Forest Road 83 passes over ancient lava flows and a mudflow from the 1980 eruption. The road provides access to Ape Cave (spur road 8303), Climber’s Bivouac (Forest Road 81, then 830) as well as Marble Mountain Sno-Park, and June Lake, Ape Canyon and Lava Canyon trailheads. Lahar Viewpoint provides visitors with a beautiful view of the south (non-crater) side of Mount St. Helens.
