Discover more about Devil's Slide Trail (South Parking Lot)

Devil's Slide Trail is more than just a scenic walk; it's a testament to human ingenuity and the power of nature's resilience. Located on a coastal promontory between Pacifica and Montara, this 1.3-mile paved trail occupies the former path of Highway 1, a stretch of road once notorious for its instability and frequent closures due to landslides. For decades, Devil's Slide lived up to its name, frustrating motorists and isolating coastal communities. The relentless forces of erosion and tectonic activity made it a constant battleground for engineers. Completed in 1937, this section of Highway 1 was plagued by road collapses and accidents. The area's geology, characterized by steep, eroded slopes and weak sedimentary rock, made it particularly susceptible to landslides. In 1940, the road closed for the first time due to erosion, and it continued to be a problem. In 1995, a major landslide closed the road for almost six months, leading locals to joke that they lived in the world's longest cul-de-sac. Even on good days, traffic would slow to a crawl as motorists carefully navigated the hair-raising turns that teetered over sheer cliffs. The solution came in the form of the Tom Lantos Tunnels, which were completed in 2013. These tunnels rerouted Highway 1 through the promontory behind the precarious cliffs, bypassing the unstable Devil's Slide section. On March 27, 2014, the former highway was transformed into the Devil's Slide Trail, a multi-use path open to pedestrians, bicyclists, and equestrians. The conversion cost nearly $2 million, but the result was a safe and accessible recreational space for all to enjoy. Today, Devil's Slide Trail offers visitors a unique opportunity to experience the dramatic beauty of the California coastline without the stress of navigating a dangerous road. The paved trail is relatively flat, making it accessible to people of all fitness levels. Along the way, there are several overlooks with benches and observation scopes, providing stunning views of the Pacific Ocean, San Pedro Point, and the surrounding landscape. Interpretive signs offer insights into the area's history, geology, and ecology. Devil's Slide Trail is also a prime location for wildlife viewing. During the winter months, California gray whales migrate south to their breeding grounds in Baja California, and they can often be spotted from the trail. In the spring, they return north with their calves, staying closer to the coastline to avoid predators. Humpback whales can also be seen year-round, though they tend to swim further offshore. Birdwatchers will find a variety of marine birds, including gulls, pelicans, cormorants, and black oystercatchers. In addition to its natural beauty, Devil's Slide Trail has a rich history. During World War II, the area was used as a military triangulation station and observation site. Soldiers would scan the waters for enemy vessels, and if any were spotted, they would radio the coordinates to gun batteries in the Marin Headlands and at Fort Funston. Today, visitors can still see the remnants of a WWII-era observation bunker, which sits atop a nearby hill. A short, unpaved trail leads to the bunker, offering panoramic views of the coastline. The trail traverses two distinct rock formations, sedimentary rock at the north end and solid granitic rock to the south. The granite, identical to rock found at Lake Tahoe and Yosemite Valley, was thrust toward the coast by forces deep within the earth. Lush native flora adorns the slopes, including California sagebrush, Indian Paintbrush, and Seaside Daisies. Devil's Slide Trail is open year-round, and there is no admission fee. However, parking is limited, and the lots can fill up quickly, especially on weekends and holidays. It's best to arrive early or consider taking public transportation. SamTrans operates a daily bus (#17) to the Devil's Slide Trail, and on weekends, a dedicated shuttle picks up from Linda Mar Beach in Pacifica. Dogs are allowed on leashes, and there are pet waste disposal stations along the trail. The trail is part of the California Coastal Trail, a 1,200-mile network of trails that will eventually extend from Oregon to Mexico. Whether you're a hiker, biker, nature lover, or history buff, Devil's Slide Trail offers something for everyone. It's a place where you can connect with nature, learn about the past, and appreciate the beauty of the California coast. Just a short drive from San Francisco, it's the perfect destination for a day trip or weekend getaway.
