Skyline to the Sea

Due to immense public interest we are offering a SECOND Skyline to Sea trip this summer. This 3-night, 4-day outing from Castle Rock to Waddell State Beach takes you on the legendary journey that has been a favorite of backpackers for 40 years. This trek spans 30+ miles of stunning ridgeline panoramas, mixed oak, madrone and redwood forests, riparian habitats, grassy meadows, spring-fed waterfalls, ending on the soft sandy beach. Adventurers will hike up to 10 miles a day, up steep hills and over sunny ridges on this challenging trip. This is the quintessential Santa Cruz Mountains backpacking experience.
