Skaggs Springs Road: Lake Sonoma to the coast

A long way from anywhere, which is the point. Skaggs Springs runs from the Lake Sonoma dam west over the ridges to the sea, and for most of that distance there is nothing beside the road but hillside.

Why this drive

Length is what sets this one apart. Most good roads here are measured in single-digit miles; this is thirty-five of them in one go, at 630 degrees of turning per mile. Fuel up before you start — there is nothing on the road itself, and phone signal comes and goes.

The route

  1. West from Lake Sonoma

    Pick up Skaggs Springs Road at the Lake Sonoma dam and head west. The first miles run above the reservoir arms before the road turns inland and climbs.

  2. Highway 1 at Stewarts Point

    The road ends on the coast highway. Turn north or south along the ocean, or turn around and drive it back the other way — it reads differently in each direction.

Good places to stop

The way back

Either drive Skaggs Springs back east, or make a longer loop: north on Highway 1 to Gualala, inland toward Cloverdale, and south again through the Alexander Valley.

Road conditions

Expect drivers, motorcycles and cyclists, especially at popular junctions and stops. Give people space, follow posted limits and check current access before setting off.
