Rainbow Harbor, 100 Aquarium Way, Long Beach, CA 90802, US

Located at the harbor in Oceanside, Helgren's Sportfishing is based out of a large blue building only steps from the water - though the real excitement begins once the boat leaves the dock. The sportfishing company offers guests a chance to fish for large, salt water fish. With rod and reel rental available, as well as sportfishing licenses, the business provides customers with everything they need to get started, including charter boats. Visitors of all ages can also enjoy shark trips, sea life adventures, whale watching excursions and more. Credit cards are accepted and on-site parking is free for up to two hours.
