Huntington Harbour is a network of man-made canals and islands located in Huntington Beach, California, offering a protected, flat-water paddling environment ideal for beginners and families. The harbour comprises five islands—Admiralty, Davenport, Gilbert, Humboldt, and Trinidad—with over 15 miles of calm canals. A 5 mph speed limit for all vessels is enforced, minimizing boat wake and creating a generally safe and peaceful waterway. The canals are sheltered from ocean swell and wind, resulting in glassy, lagoon-like conditions, particularly in the mornings before afternoon sea breezes may develop.

Primary public access points for launching kayaks, canoes, and paddleboards are concentrated in the adjacent Sunset Beach area. Launch sites include the small sandy beach at Trinidad Park on Trinidad Island, which has restrooms and showers; Davenport Beach, also known as "Mother's Beach," on Humboldt Island; and the public launch ramp near the Huntington Harbour Yacht Club on Warner Avenue. Other noted launch areas are Sunset Aquatic Park at the north end of the harbour off Edinger Avenue and the 11th Street ramp in Sunset Beach. Several commercial rental operators, including Everyday California, Huntington Harbor Boat Rentals, and OC Paddlesports, are also located in Sunset Beach, providing gear and launching services steps from the water.

Paddling here is a scenic tour of a residential marina community. Routes pass by luxury waterfront homes, docks lined with boats, and charming bridges. Notable landmarks accessible from the water include small neighborhood parks like Seabridge Park and Trinidad Park, which offer picnic areas and beaches. Wildlife sightings may include great blue herons, egrets, sea lions, and dolphins. The water in the harbour is typically 3–4°F warmer than the adjacent ocean in the summer, making it comfortable for year-round paddling. Key safety considerations involve being aware of boat traffic in the main channels and caution around bridges, such as the one near Trinidad Park, where jumping is illegal and shallow water may be present at low tide. The best times to paddle are mornings and weekdays for fewer crowds and calmer conditions.
