Sydney's best snorkel: a west-facing pocket of sand inside a no-take aquatic reserve, where blue gropers and turtles cruise metres from shore.
FreeFamily
Shelly Beach hides in the corner of Cabbage Tree Bay, a ten-minute stroll along the promenade from Manly’s crowds — and a different world once your mask hits the water. The whole bay is a no-take aquatic reserve, so the fish behave like locals: metre-long blue gropers, dusky whaler pups, rays, octopus and more than 160 recorded species within a leisurely snorkel of the sand.
Snorkelling the reserve
Enter from the beach and work the rocky edges of the bay — the northern side toward Fairy Bower has the densest life. Visibility peaks on calm mornings before the afternoon nor’easter. It’s also Sydney’s favourite shore-dive and a gentle swim for kids, being one of the few west-facing (and thus usually flat) ocean beaches on the coast.
Beyond the water
The grassy reserve behind the sand has barbecues and shade, the Bower cafe does the post-snorkel coffee, and the short headland loop above the bay serves whale watching in season. Pair it with a Manly-to-Spit walk or Sydney’s other secret beaches, and browse more photography spots nearby.

Photography Tips
Underwater: shoot gropers against the kelp on the northern edge, morning light. Above water: the headland steps frame the whole bay.
Insider Tips
It is a no-take reserve — no fishing or collecting. Arrive early on weekends; the small car park fills by 8 am, so walk from Manly instead.
Getting There
Ferry to Manly, then walk 10 minutes south along Marine Parade past Fairy Bower to the beach.

How do you get to Shelly Beach?
Take the ferry to Manly and walk 10 minutes along the Marine Parade promenade; driving is possible but the tiny car park fills very early.
Can you fish at Shelly Beach?
No — the entire Cabbage Tree Bay Aquatic Reserve is no-take, which is exactly why the snorkelling is so good.
