Frequently asked questions

How long is the Skyline to Sea Trail and how many days does the Skyline to Sea Trail take?

The Skyline to Sea Trail is about 38.96 km, or roughly 24.2 miles, with around 699 m of elevation gain. Most backpackers take 2 to 3 days to complete it, while strong day hikers sometimes cover it in one long push. California State Parks also describes the route as a multi-day backpack from the crest of the Santa Cruz Mountains down to the Pacific coast at Waddell Beach.

Where does the Skyline to Sea Trail start and finish in Santa Cruz County?

The classic Skyline to Sea Trail route starts near Castle Rock State Park along Highway 35 in the Santa Cruz Mountains and heads west through Big Basin Redwoods State Park toward the coast. The traditional finish is at Waddell Beach in the Rancho del Oso area, where the trail meets Highway 1 near the Pacific Ocean.

Is the Skyline to Sea Trail fully open all the way to Waddell Beach right now?

No. California State Parks currently says the Skyline to Sea Trail is open from Castle Rock State Park to the Big Basin day-use area, but the coastal Skyline to the Sea segment near Rancho del Oso is closed 0.4 miles past the Highway 1 entrance because of damage from the 2020 CZU Lightning Complex Fire. That means the full through-hike to Waddell Beach is not currently available as a continuous open route.

Where can you park for the Skyline to Sea Trail at the Castle Rock and Waddell Beach ends?

At the north end, hikers commonly use the main parking lot at Castle Rock State Park on Highway 35, where California State Parks lists a vehicle day-use fee. At the coast, day hikers can park in the lot adjacent to Waddell Beach or along the inland side of Highway 1 near Rancho del Oso. Overnight parking for backpackers is limited to designated trailhead parking lots.

Are dogs allowed on the Skyline to Sea Trail?

Dogs are not a good fit for the Skyline to Sea Trail. Castle Rock State Park prohibits dogs on park trails except for service animals, and Big Basin Redwoods State Park does not allow dogs on the trail system; Rancho del Oso and Waddell State Beach also prohibit dogs. In practice, that means the route is not dog-friendly.

Is the Skyline to Sea Trail hard, and is the Skyline to Sea Trail suitable for beginners?

The route is generally considered easy by long-distance trail standards because it trends downhill from the Skyline ridge toward the coast and has about 699 m, or 2,293 feet, of total elevation gain over nearly 39 km. The bigger challenge is endurance, logistics, and current closures rather than steep technical terrain. It suits fit beginners with solid preparation for a full-day hike or an overnight trip.

What are the main highlights on the Skyline to Sea Trail?

The Skyline to Sea Trail links several of the best-known landscapes in the Santa Cruz Mountains. Highlights include the sandstone scenery and ridge views around Castle Rock State Park, long stretches of redwood forest in Big Basin Redwoods State Park, and the traditional coastal finish near Waddell Marsh and Waddell Beach on the Pacific. The route is especially known for moving from mountain crest to ocean in one continuous westbound journey.
