California trails · Skyline To The Sea Trail
A 18.1-mile network in California, with 1,975 ft of climbing. Reaches Bulls Spring and other beach/spring/viewpoint/waterfall destinations. Managed by the state.
The climbing leans toward the middle third: 53% of the ascent falls between mile 6.8 and mile 13.7. It gives back about 1,629 ft along the way, so it rolls rather than climbing steadily.
