The Hike
Start at the park trailhead

Climb toward the summit
Follow the signed summit route through forest and chaparral. The former Stevenson cabin site is marked along the way.
Return with daylight to spare
Retrace your route. The summit trip is about 10 miles out and back, so plan your turnaround before starting.
Getting Here & Parking
The park is about seven miles north of Calistoga on Highway 29. Use the signed dirt parking area and follow current signs.
The park operator lists limited parking and no entry fee. There is no drinking water, restroom or trash collection; arrive prepared and pack everything out.
