The Tijuana Estuary Visitor Center is the best thing to do in Imperial Beach.
It sits at the end of Caspian Way, the room inside is free and staffed by
people who can tell you what you are looking at, and the trails run straight
out from it into a salt marsh that reaches the border.
The rest of it is a pier town. The Port's art route threads surfboard-shaped
markers through the pier district, the bikeway runs flat and north toward
Silver Strand, and there is a park above the beach with a basketball court and
picnic tables on it.
The ocean itself is closed. Sewage carried up the coast from the Tijuana River
has the County holding a water-contact closure across the whole Imperial Beach
shoreline, from the south end of Seacoast Drive to north of Carnation Avenue,
and it has stood since late 2025. Check
sdbeachinfo.com the morning you go, read the
signs on the sand, and build the day on land.
Start at the estuary while the boardwalks are still cool and let the pier have
the end of the day. For a beach you can get into, the county beach
ranking is the better page. Best
sunset spots covers the
golden-hour version of this coast, and the best hikes in San
Diego picks up if the estuary trails leave
you wanting a longer walk.
