Robert Louis Stevenson State Park is 5,272 acres and contains views of Napa, Sonoma, and Lake Counties from the summit of the highest peak in the California Wine Country, Mount St. Helena. The park is mostly undeveloped and hiking and biking are the main activities at Robert Louis Stevenson State Park. Parking can be found in a dirt lot just off Highway 29. The parking lot is about 7.5 miles north of the intersection of Highway 29 and Silverado Trail in Calistoga. The park is marked with signs.

This mostly undeveloped park is home to the area where Stevenson and his bride spent their honeymoon in an abandoned bunkhouse of the Silverado Mine. A marble memorial marks the site of the bunkhouse. Stevenson’s stay in 1880 inspired the writer’s travel memoir The Silverado Squatters, and Mount St. Helena is thought to be a portrait of Spyglass Hill in Treasure Island.

The trails to the west climb to the summit of Mount St. Helena, overlooking Napa and Lake Counties. On clear days, the Pacific Ocean, the Sierra Nevada Mountains, Mount Shasta and Mount Lassen are visible.

The trail to the southeast lead hikers to Table Rock, the volcanic cliffs of the Palisades and a connection to the Oat Hill Mine Trail and the outskirts of the City of Calistoga. As the park is large, hikers and bikers can find a variety of nature to explore.

The trails to the southeast lead hikers to Table Rock, the volcanic cliffs of the Palisades, and a connection to the Oat Hill Mine Trail. This section mostly overlooks the Napa Valley and takes you into the backcountry of northern Napa County. The trail leads through grassy hillsides, oak groves, and chaparral with amazing volcanic rock formations to explore.  

Robert Louis Stevenson State Park is operated by the Napa County Regional Park and Open Space District.
