San Dieguito River Park Lagoon Trail
This is a personal-favorite family walk along the San Dieguito Lagoon. It is a great option when you want nature, wildlife, and an easy trail without steep climbs. The flat dirt path works well for strollers, trail bikes, and kids who like to explore.

What makes this trail special
This trail keeps kids engaged without needing a destination. The lagoon is constantly active, which makes the walk feel more like an experience than just exercise.
Wildlife to watch for
Families often spot ospreys, great blue herons, and egrets. Another fun surprise is the mullet fish, which frequently leap out of the water.
But the biggest highlight for many kids is the swallows nesting beneath the I-5 bridge.
What families should know
The trail is flat and easy, but restroom access is limited. Plan ahead since the only restrooms are at the Del Mar dog park.

- Water and snacks
- Binoculars for bird watching
- Stroller or bikes if needed
- Sun protection
Why this is such a great outing
This trail makes nature accessible for families. It is easy enough for a casual outing, but memorable enough that kids will talk about the birds, nests, and jumping fish afterward.
