Shelly Beach (Cabbage Tree Bay)
Sydney's most forgiving shore entry, inside a protected aquatic reserve at Manly.
Shelly Beach sits within the Cabbage Tree Bay Aquatic Reserve at Manly, and the protected waters are particularly popular for snorkelling and entry-level diving.
Marine life can include blue gropers, rays, wobbegongs and other temperate species, and the protection means they are habituated and easily approached.
It is one of the easiest shore entries in Sydney, which is why so much of the city's training happens here.
