The Sky Trail Loop Run is a great trail to hike, or backpack across the roof of Point Reyes National Seashore, California. You'll pass its highest point Mt. Wittenberg all the way down to Sculptured Beach at the Pacific Ocean.
Sky Trail in Point Reyes National Seashore is a dramatic, mostly single-track trail that runs along the main spine of the Inverness Ridge and across highest mountains in Point Reyes, looming above the Olema Valley and Highway 1 which mark the San Andreas Fault rift zone and the dividing line between the Pacific and North American plates. The trail takes you through several ecological zones including massive stands of Eucalyptus, Cyprus, and Bishop Pines, including an area that was burned during the massive Vision Fire in 1995, which burned some 12,000 acres in the park.
The highlight of the trail is the 1.5 stretch that begins at the intersection with Baldy Baldy Trail and descends a ridgeline dramatically over the Pacific Ocean, providing breathtaking views up and down the coastline, from Mt Tam & San Francisco across Drakes Bay and Limantour Beach to Point Reyes and the Lighthouse.
The trail can be done either as an out-and-back or more commonly as a loop with either Coast Trail to Bear Valley or Coast Trail to Fire Lane.
The most direct route is an out-and-back beginning at the trailhead on Limantour Road, which can be reached via Bear Valley Road, Sir Francis Drake Blvd., and Highway 1 very near to Point Reyes Station.
