The oldest of the California State Parks, Big Basin is well worth your time. The park stretches across the Santa Cruz Mountains and towards Los Gatos on the eastern ridge.
With so many hikes it is hard to choose. Grab a trail map from the visitor center. There are a few favorite trails worth mentioning. Berry Creek Canyon is tough, but rewarding trail with one of the Bay Area’s best waterfalls. Other hikes include the trek to Sempervirens Falls, or the Redwood Trail, both easier for children. The beloved 25-mile Skyline to Sea trail takes you from the redwoods to the sea. You’ll either need to park one car at the start and another at the end, or plan to camp at the bottom and hike back up. Mountain bikers use fire roads and the paved North Escape Road.
There are 146 campsites in the park, located in 4 campgrounds (you’ll need to reserve ahead for these at 800-444-7275). You can also rent tent cabins.
