A beautiful riverfront park in the California Delta, just minutes from Isleton and Rio Vista, California. The Marina is in Sevenmile Slough, just off the San Joaquin River at channel marker 41. The natural, serene setting and proximity to the Sacramento and Mokelumne Rivers offer abundant opportunities for outdoor activities.

The location offers the convenience of being on the famous 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.

This is a private marina for tenants and their guests to enjoy the quiet and tranquil 20 acres of beautiful, green, park like setting. The abundant wildlife, seals, birds and fishing will take your breath away. Have a wonderful walk around the levee to view the San Joaquin River or sit back and take in Mt. Diablo for a sunset.

Owl Harbor is home to approximately 200 vessels and the location for Andreas Cove Yacht Club. The natural, serene setting and proximity to the Sacramento and Mokelumne Rivers offer abundant possibilities for outdoor activities. Owl Harbor Marina is the place to come and do as much or as little as you want – the opportunities are endless...we believe in keeping it simple, enjoyable and within reach.
