Though it can be a bit confusing to differentiate between the Del Mar beaches, they are easy to find and walk between each one. South Beach is defined as south of Powerhouse Park all the way down to 6th Street at the southern end of Torrey Pines State Beach. This section is less popular for swimming and surfing than the neighboring Northern portion, but the high, jagged cliffs above it make for a beautiful and scenic beach walk.
North of Del Mar City Beach is one of just a few dog beaches in San Diego, and the locals are passionate about keeping it that way. Your pup is allowed on the beach year round, and off-leash for nine months out of the year, but must be leashed from June 16th until Labor Day. While this area is mostly known for being Fido-friendly, the San Dieguito River Mouth provides a natural wading pool that is great for children to play in.
Del Mar City Beach starts at Powerhouse Park or 15th Street and stretches all the way up to the lagoon entrance at the San Dieguito River (where it meets Dog Beach). It’s a hot spot for swimming, sunbathing, and surfing, and is usually crowded on the weekends. There is almost always a lifeguard on duty, and the park above provides restrooms and picnic tables in addition to a large grassy area and a sandbox play area for children.
