Voted Best Marina in the Delta 2 years in a Row!

The Tenants and Guests of Owl Harbor Marina have dubbed us “The Best in the Delta,” a “hidden gem,” and a “must experience.” Tucked away amid the quiet waters of Sevenmile Slough, just off the San Joaquin River, with 20 acres of park-like setting, an abundance of wildlife, and breathtaking views that feel never-ending. The tempo here is slower, creating an atmosphere that fosters relaxation, ambling walks, the enjoyment of simple pleasures, and more time for fun.

A beautiful riverfront park in the California Delta, just minutes from Isleton and Rio Vista, California. The location offers the convenience of being on the Delta Loop with easy vehicle access to the Delta Highways 12 and 160 and is a straight shot from Freeways I-80 and I-5. Just a little over an hour’s scenic car ride from San Francisco, Pt. Richmond, Oakland and San Rafael and less than an hour’s car ride from Sacramento, Walnut Creek, Martinez, Antioch and Vallejo – we are a short distance away from all of these locations and more, so that you can get to your boat more often and quickly to enjoy your time of escape.

By vessel, it doesn’t get any easier, located just off the San Joaquin River at channel marker 41, with plenty of water to get to your slip at any time. It is an easy, and enjoyable trip, with no draw bridges to contend with coming from the Bay Area.

We are a private, gated marina for tenants and their guest to enjoy the tranquil 20 acres of our beautiful, green, park like setting. The community feeling comes naturally and all are welcome to do as much, or as little, as you like. We are a step back in time but with modern amenities that individuals and families enjoy. Every slip has a private view and every dock has easy access for entering or departing for your adventure to explore. We are not like most marinas, which is what makes us stand out from them all.
