Narrabeen Lagoon

Narrabeen Lagoon is the largest coastal lagoon system in Sydney, located in Narrabeen within the Northern Beaches local government area of New South Wales. Covering about 2.2 square kilometres, it is separated from the ocean by Narrabeen Beach and connected via a narrow entrance. Notable for its 8.4 km multi-use trail, diverse birdlife, and recreational waters, it is a central natural attraction for walking, cycling and water sports.

Visitors can expect a large, shallow coastal lagoon surrounded by parklands, reserves and residential areas. An 8.4 km flat, mostly paved loop trail circles the lagoon with bridges, boardwalks and lookouts. The setting includes mangroves, reed beds, open water and sandy foreshores. Visitors can walk, jog or cycle the trail, launch kayaks and stand-up paddleboards, fish from designated spots, picnic in reserves, and observe waterbirds. Several reserves around the lagoon provide playgrounds and barbecue areas.
