The Garden of Eden is a beloved swimming hole tucked into the redwoods of Henry Cowell Redwoods State Park near Felton, California, in the Santa Cruz Mountains. Strung along the San Lorenzo River beneath towering redwoods and Douglas firs, this sun-dappled oasis — with its clear green pools, little sandy beaches, and rocky ledges — has been a favorite Santa Cruz summer escape for generations.

It's an idyllic spot to spend a warm afternoon: swim in the cool river, sunbathe on the rocks and small beaches, and watch the light filter down through the redwood canopy. Some ledges draw cliff-jumpers when the water is deep enough, though “No Diving” signs are posted for good reason — more on that below.

Getting there is a little adventure with an important catch: the most common route follows an active railroad line (the Roaring Camp scenic railway). From the Ox Trail parking area off Highway 9, you hike down and then walk along the train tracks for about a mile to reach the swimming hole. These tracks are active and trains do run — people have been seriously hurt and killed here. Stay alert, step well clear of the tracks whenever a train approaches, skip the headphones, and keep kids close. And heed the “No Diving” signs: always check the depth before entering, since the river bottom and water level change.

A few more notes: there are no restrooms or trash cans, so pack out everything you bring in, and dogs are not permitted. Arrive early on summer weekends, as roadside parking fills fast. Summer and early fall, when the river warms and the flow settles, are the best times to visit. Mind the trains, respect the river, and the Garden of Eden rewards you with one of the most beautiful swimming holes in the Santa Cruz Mountains.
