Castaic Lagoon Access provides a designated launch ramp for non-motorized and electric-powered vessels on the lower lagoon, which is restricted to hand-powered, sail, or electric trolling motors only.

The lagoon launch ramp requires a daily permit ($9 for non-motorized, $13 for motorized vessels) and all watercraft must pass a mandatory aquatic invasive species inspection before launching.

Additional amenities at Castaic Lake State Recreation Area include parking, restrooms, and picnic facilities, with the park open sunrise to sunset Wednesday through Sunday.
