Santa Cruz Rail Trail
Me walking across a railroad bridge.
The Big Trees Roaring Camp Railroad between Santa Cruz and Felton is the popular walking and biking trail. It roughly parallels Highway 9 and the San Lorenzo River to take you through Henry Cowell Redwoods State Park.
This is an active railroad, so be sure you know the train schedule if you walk or ride on these rails. It's a tourist railroad with no trains during the winter.
