Gray Whale Cove Trail climbs the coastal bluffs just south of Devil’s Slide along Highway 1, offering some of the most dramatic ocean views on the San Mateo County coast. The out-and-back trail gains about 150 feet of elevation as it winds above the cove, with sweeping vistas of rocky headlands, crashing surf and the Pacific stretching to the horizon. At approximately 2.3 miles round trip, this is an easy route that takes under an hour to complete, making it perfect for a quick outing with your dog.
Dogs are allowed on leash on the trails east of Highway 1, with leashes required to be no longer than six feet at all times. The path is mostly dirt and can be narrow in spots, so keep your dog close on the bluff-top sections where the terrain drops away steeply. The trail surface is well-maintained but can become muddy after rain, so plan accordingly during the wetter months. Pet waste bags are a must here, as there are no waste stations along the route itself.
On clear days, you can see north to the Marin Headlands and south toward Montara Mountain, and during winter and spring, migrating gray whales are sometimes visible offshore, which is how the cove earned its name. Wildflowers line the trail in spring, adding brilliant splashes of color to the already stunning coastal scenery. The combination of ocean breezes, sweeping panoramas, and seasonal whale sightings makes this one of the most rewarding short hikes on the San Mateo County coastline.
The trailhead parking lot is located on the east side of Highway 1, which also provides access to McNee Ranch and Montara Mountain for those looking for a longer adventure. The lot can be easy to miss, so look for it on the ocean side of the road just south of the Tom Lantos Tunnels. Parking can fill up quickly on weekends, especially during whale-watching season, so arriving early is recommended. From the parking area, you can also connect to trails leading up into the hills for more challenging elevation gains if your dog has energy to spare.
Below the trail, stairs lead down to Gray Whale Cove beach, though dogs are not permitted on the beach itself, so this is a trail-only adventure for your canine companion. Despite that restriction, the bluff-top views are spectacular and more than make up for skipping the sand. This is a rewarding short hike for dogs and owners who love rugged coastal landscape without a long time commitment, and it pairs perfectly with nearby Devil’s Slide Trail for a full morning of coastal exploration.
