The Lighthouse Circuit

Access, tours, hours, fees, and closures change often. Always verify with the official source before driving.

Tier 2

Discovery Bay Lighthouse

Discovery Bay · Contra Costa County · California Delta

California's lighthouse story did not end with the historic Coast Guard stations. Discovery Bay is a modern Delta light: a working local reference, a civic landmark, and a reminder that communities still build towers to welcome people home from the water.

At Discovery Bay Lighthouse? Save a private Passport mark for your own records. That mark is not a verified check-in and never creates a public Visitors entry. Where an approved proof point is active, use a fresh location reading to verify the visit separately.

Checking for an approved location proof point…

Private Passport marks and verified check-ins are different records. Location verification uses exact coordinates once and does not store them. Publishing a verified visit in the Visitor Logbook remains optional and always a separate opt-in.

The story

Built in 2013 at the entrance to Discovery Bay's dredged waterways from Indian Slough, this modern tower is a privately maintained, unofficial aid to navigation and a community landmark, not a historic federal light station. Reclamation District 800 describes Discovery Bay as the first Delta community to have a lighthouse.

The visit

The white octagonal tower stands at the entrance to Discovery Bay's waterways. The site is reported open for exterior viewing, but the tower is closed. Respect marina and waterfront boundaries, and confirm current access before making a dedicated trip.
