Where we are
Sunset Harbor sits on Dutch Slough at the foot of the Bethel Island bridge, so a berth here is a berth in the middle of the Delta rather than at the end of a long run out to it. The office is at 3040 Dutch Slough Rd in Oakley, which puts the boat about as close to home as it gets for anyone in Oakley, Brentwood, Antioch or Discovery Bay — you drive over, walk down the dock and go, instead of hitching up a trailer first. If you are looking at boat slip rental on Bethel Island, come and walk the docks before you decide; the office is open 24 hours, 7 days a week.
