The Sea Cliff Coastal Bluff Trail in Del Mar is a scenic hiking path accessible from 4th St in Del Mar, CA 92014, running along dramatic sandstone bluffs above Torrey Pines State Beach with views stretching south to La Jolla and north toward the Del Mar Fairgrounds. This out-and-back trail has gone viral on TikTok and Instagram for its cinematic vantage points, particularly during spring when native Sea Lavender blankets the bluffs in purple and the Amtrak Surfliner passes along the railroad tracks below. The trail is open 24 hours and offers an easy, mostly flat walk suitable for all fitness levels, though hikers should stay on the established paths because the sandstone cliffs are eroding and there are no guardrails or fencing along the edges. Dogs on leash are welcome, and the trail has become a popular sunset walk for residents of the surrounding neighborhood. Street parking is available in the residential area near the 4th Street and 6th Street access points, and additional trail entry can be found near the intersection of Carmel Valley Road and South Camino Del Mar where a bench known locally as the Sunset Seat overlooks the Torrey Pines Bridge, the railroad, and the ocean in a single frame. Just north along the coast, Sea Grove Park provides a blufftop rest stop with benches, walking paths, and ocean overlooks. The trail connects visually and geographically to the broader network of coastal parks, and visitors often combine it with a walk through Powerhouse Park for a full afternoon along the Del Mar shoreline. Rated 4.8 stars on Google with over 100 reviews, the Sea Cliff Coastal Bluff Trail has earned a reputation as one of San Diego's best-kept coastal secrets.
