The Devil’s Slide Tunnel opened this morning in time for commuters traveling between Pacifica and Half Moon Bay. For those on feet, hooves or bikes, the former path of Scenic Route 1 will be transformed into a trail with breathtaking views of soaring cliffs with crashing surf below. Please mind the edge!

“After the tunnel opens to traffic, Caltrans will block off the troublesome 1.1-mile stretch of Highway 1, build parking lots at either end and hand it over to San Mateo County, which will turn it into a hiking and biking trail with a great view.”
