Collins Flat Beach

Collins Flat Beach is a small, sheltered harbour beach located in Manly within the Northern Beaches Council area of New South Wales, on the edge of Sydney Harbour National Park near North Head. It is notable for its calm, clear waters, sandy shoreline backed by bushland, and tranquil setting away from ocean surf beaches. The beach is popular for swimming, picnicking and harbour views.

Visitors can expect a small, sheltered sandy cove on Sydney Harbour with calm, shallow water suitable for swimming and wading. The beach is backed by bushland and parkland of Sydney Harbour National Park, with a grassy reserve, picnic tables and a small waterfall nearby. The setting is quiet and natural, with views across the harbour, moored boats, and walking tracks connecting to Collins Beach, Little Manly Cove and North Head. There is no surf and no commercial development directly on the beach.
