Shelter Island Boat Ramp is a multi-acre facility at the northwestern end of San Diego Bay offering the closest public access to the Pacific Ocean (approximately 3 miles away) with four or more launch lanes, ample docking space, restrooms, and a large trailer parking lot at no launch fee.

The facility features 24-hour bait barges on the right side of the channel as you exit the harbor, making it convenient for fishing enthusiasts. This is one of four primary public boat launch facilities in San Diego Bay operated by the Port of San Diego.
