The 805-acre reserve, 2 miles north of Guerneville, is a place of peace, silence, and very big redwood trees—some of them are more than 300 feet tall and at least 1,400 years old. The moistness of the air means that when the sunlight does manage to break through the density of the ecosystem, it can draw steam off the bark of the mighty trees, creating a seriously beautiful environment. Save the entrance fee by parking at the visitor’s center and walking in. There are a few trails, but overall, it’s not busy, so it’s often pin-drop quiet.
