Robert Louis Stevenson State Park to Mount St. Helena Spur:
5 miles one way for hikers; 5.5 miles one way for multiuse route (plus 5-mile or 5.5-mile return)
From: CA 29 in Calistoga (5.9 miles north of Tubbs Lane)
To: Mount St. Helena Summit
Mount St. Helena, the second-highest mountain in the Bay Area, is the northernmost point of the Ridge Trail. The summit is at 4,343 feet, and the views from the trail and at the top are spectacular. The dedicated Ridge Trail is the multiuse fire road, which has inadequate parking at the trailhead; extreme caution is advised along busy CA 29. It is recommended that hikers take the Stevenson Memorial Trail, the hiking-only connector from the main parking area (the Table Rock Trail is on the opposite side of CA 29). If taking this trip in the summer, start early to minimize sun exposure.
Elevation Gain/Loss 1,790 feet/15 feet one-way for hikers, 1,990 feet/15 feet one-way for multiuse route
