The marina

Bethel Island, on Dutch Slough — the ramp, the docks and the water you get to from them.

Where we are

The office is at 3040 Dutch Slough Rd, Oakley, CA 94561 — on Dutch Slough at the foot of the Bethel Island bridge, which is the point: this is not a marina at the end of a long run out to the Delta, it is a marina in the middle of it. For anyone in Oakley, Brentwood, Antioch or Discovery Bay, keeping the boat or the RV on Bethel Island means driving over and going, rather than hitching up a trailer first every time the weather is good. Come and walk the docks before you decide — the office is open 24 hours, 7 days a week, and there is a map here.

Ask about a space

Tell us what you have and roughly when you want to move in, and the office will come back to you. Prefer to talk? Call (925) 453-9471 — the office is open 24 hours, 7 days a week.

We only use this to answer your question. Leave a phone number or an email — either is fine.
