The 1.3-mile “Devil’s Slide” segment of Highway 1 just south of Pacifica is the latest addition to San Mateo County’s 20 parks. The freshly-paved walking and biking trail offers spectacular views of the Pacific Ocean and its coastal cliffs, and it’s by far the widest trail in the San Francisco Bay Area, with 12 feet striped for walking and 12 feet for bicycling.
“This is inarguably one of the most beautiful segments of the California Coastal Trail,” said Coastal Conservancy Executive Officer Samual Schuchat at the trail’s ribbon cutting ceremony Thursday. “It’s incredibly exciting to open it, after years of driving through here and wanting to take in these views but being afraid that you would crash.”
The geologically hazardous section of highway was closed to cars in March of last year with the opening of the twin Tom Lantos tunnels, which Caltrans constructed to bypass this stretch. As Deidra Kennedy of the Pacifica Historical Society told the SF Chronicle last week, Caltrans originally planned to build an inland bypass and bury the Devil’s Slide highway, but local activists persuaded them to instead build a tunnel and re-purpose the coastal road.
Construction included re-paving the road, building parking lots, bus stops, and public restrooms at both ends, and adding three overlooks, 12 benches, and a variety of educational panels alongside the trail to help visitors learn about the area’s geology and ecology. The San Mateo County Parks Department spent $2 million on the highway-to-trail project, and will invest another $492,000 per year to maintain it, or roughly 5 percent of the department’s annual budget.
Getting to the new trail without a car, however, is a challenge. Since the trail was carved from Highway 1, the highway remains the only way to get there.
