Sea Cliff Coastal Bluff Trail in Del Mar. To get to this trail you will need to go into the residential neighborhood of Del Mar and find street parking. You can enter from 6th Street or even 4th Street. The quintessential trail that gives California vibes. This is a great walk with awesome views of the coastline, surfers, people walking their dogs and runners. It parallels the Coaster train tracks so ALWAYS be aware of on coming trains. You will need to cross the tracks to get to the trail side below. The bluffs are beautiful, etched with time but keep a safe distance from the edge. The iconic Torrey Pines Bridge can be seen as you walk south. There is plenty of room but it’s better to stay on the trail next to the vegetation and away from the tracks. I would only keep 1 AirPod in so you can hear trains coming.
