Devils Slide Trail on the old Highway One alignment
Between Pacifica and Montara on the San Mateo coast, California

Devils Slide was always a major trouble spot on Highway One in San Mateo county, frequently closed by rock fall or roadway collapse, always jammed with traffic. The shoulders were fenced off and you weren't allowed to stop, so you couldn't appreciate the view.

The active area has now been bypassed with a twin-bore tunnel that cuts behind the slide. The old roadbed has been repaved and set up as walking and biking route a mile and half long.

Highly recommended. The views are great and birders love it. It is between Pacifica and Montara on Highway 1, with parking and restrooms at both ends.

The old highway comes through a deep roadcut and suddenly is on the open bluffs above the ocean. There is a nice viewpoint here, just a short walk from the parking lot on Highway 1.
