Robert Louis Stevenson State Park is the place where the famous author of Treasure Island and Kidnapped spent his honeymoon in 1880. Although nothing remains of Stevenson’s cabin, the site is identified on the trail to the summit. 

The area features rough terrain, with evergreen forests in the canyons on north-facing slopes and chaparral on the south-facing slopes. 

There is a five-mile hike to the top of Mt. St. Helena from which one can see much of the San Francisco Bay Area. On good days the top of Mt. Shasta can be seen, 192 miles in the distance. 

To protect the park's wildlife and other natural resources, dogs are not permitted in this park.
