Hiking
The Skyline To The Sea Trail offers a remarkable journey from the Santa Cruz Mountains to the Pacific Ocean, immersing you in continuously evolving landscapes. You'll trek through gnarled oak forests and chaparral, eventually entering lush, dark canyons filled with magnificent coastal redwoods, particularly within Big Basin Redwoods State Park. The path winds alongside serene creeks, culminating in the dramatic sight and sound of the ocean at Waddell Beach, a truly rewarding finish to this diverse route.
This difficult point-to-point hike covers 34.5 miles (55.5 km) with 4924 feet (1501 metres) of elevation gain, typically requiring 16 hours and 16 minutes to complete. You'll need to arrange transportation from Waddell Beach, as there's no public shuttle. Backcountry camp reservations are essential and should be secured well in advance, especially if you're planning a multi-day trip. Always check the current status of the trail, particularly after the CZU fires, before heading out.
Connecting Castle Rock State Park and California's oldest state park, Big Basin Redwoods State Park, this trail is one of the most popular backpacking destinations in the San Francisco Bay Area. While generally descending towards the sea, expect significant elevation changes and varied terrain, including rocky sections and exposed roots. The final day, traversing through old-growth wilderness, is often highlighted as the most scenic portion of the entire hike.

The trail typically starts at elevations around 2,600 to 3,000 feet, often from Saratoga Gap or Castle Rock State Park. Parking availability varies by trailhead, and it's crucial to plan your transportation for the end of the point-to-point hike, as no shuttle services are provided.
What kind of terrain can I expect on the trail?
The terrain is highly varied. You'll start with more exposed areas offering mountain views, transitioning into dense, lush coastal redwood forests, following creeks like Opal Creek and Waddell Creek. Expect singletrack paths, old logging roads, and dirt roads. Some sections might even include boulder scrambling or a short cable-aided part, particularly near Castle Rock.
What can I see along the route?
