There are 200 miles of trails that weave through the trees and canyons in the parks. Hike around Stout Grove or Lady Bird Johnson Grove, head down the breathtaking Tall Trees Trail, or walk along the floor of the famously lush Fern Canyon—an inspiration for the movie Jurassic Park. Take plenty of photos as you walk between the rock walls covered in thick ferns. While the giant redwoods are the most well-known attractions in the park, paths like the Coastal Trail traverse beaches and rivers as well. Because of the dampness and shade under the trees, many of these trails are accessible only by quaint bridges and wooden walkways—forcing them to close at times during the wet winter months.
