Long Reef Beach, in Dee Why in the Northern Beaches region, is a continuation of Dee Why Beach which lies between Dee Why Lagoon and the Tasman Sea. The Long Reef Aquatic Reserve starts at the northern end of Long Reef Beach.
The Dee Why beaches feature good waves for surfing but rips can prove hazardous to swimmers.
Because of its accessibility by car via Pittwater Rd — and with good parking, park and picnic facilities — the Dee Why beaches are a drawcard for visitors.
Those out for a swim are advised to remain between the flags.
