Just southeast of Big Basin Redwoods State Park is Henry Cowell Redwoods State Park. It’s a smaller park and has about 15 miles (24 km) worth of hiking trails. The Redwood Grove Trail is actually self-guided, but you can opt for the guided walks through the 300-foot-tall “virgin” redwoods on the weekends. You can also try joining the Roaring Camp Railroads tour for a unique tour experience.
