Long Reef is a perfect stretch of white sand. At the north end there is Long Reef Headland, a protected aquatic reserve, and a golf course. A walk to the top of the headland can often be rewarded by views of migrating whales.
There are offshore reefs in the north (the Long Reef Bomboras) and beach breaks running the entire 1.6 kilometres south to Dee Why and, on weekdays there's every chance of getting a quality wave to yourself.
The Long Reef Bomboras starts to break at one metre or so and in a big south swell can produce a beautiful wave up to five metres. Reliable sandbanks shape beach breaks that are great for beginners and intermediate surfers. North Long Reef is also a favourite for windsurfing and kitesurfing.
