Long Reef Aquatic Reserve is located on Sydney's northern beaches, approximately 20 km north of Sydney city.
To get to Long Reef Aquatic Reserve:
 
Long Reef Aquatic Reserve includes Fishermans Beach at Collaroy, a sheltered sandy beach on the northern side of the headland, the very exposed and rip-dominated northern end of Long Reef Beach, and some very small areas of sandy beach in amongst the rocky shore on Long Reef headland itself.
Views from the top of Long Reef headland show the extensive rocky shores of the aquatic reserve.
The southern side of Long Reef headland has wide, flat rock platforms.
The visually stunning geology of Long Reef headland shows the oldest units of early Triassic sediments from the Narrabeen group.
Long Reef has the most variety of rocky reef habitats found anywhere in the Sydney basin, and this provides for a diversity of marine plants and animals.
Fishermans Beach (in the distance of this photo) on the northern side of the headland is a relatively protected beach surrounded by rocky areas. It is popular for swimming, boating and snorkelling.
The reserve is regularly used by university students conducting research, here snails have been marked as part of a research project.
