About the San Dieguito River Trail
The western end of the Coast to Crest Trail, San Dieguito River Park's flagship corridor that eventually runs all the way to Volcan Mountain near Julian. This lagoon-side stretch is flat, easy, and built for birding — osprey nest platforms, wide water views, and an interpretive walk with QR codes along the way.
It's an easy pairing with a day at the beach: park at the staging area, walk the lagoon loop, and you're back at the car in under an hour.

Nobody on this desk has hiked the slot yet, so we’re not going to fake it. This space is reserved for Kendall’s own first-hand account once he’s made the trip — the ladders, the squeeze, what it’s actually like up there.
