Quarantine Beach is a serene, crescent-shaped haven located on the northern tip of Manly, nestled within the historic Q Station precinct. This 200-meter sandy stretch is renowned for its calm, clear waters, making it an ideal spot for families seeking a peaceful beach day. Protected by surrounding rocks and the lush bushland of North Head, the beach offers a natural swimming pool experience. It's a perfect place to swim, snorkel, or simply relax by the water.

The beach is part of the Sydney Harbour National Park and has been a designated aquatic reserve for over four decades, ensuring its waters remain pristine and teeming with marine life. Visitors can enjoy activities like kayaking, stand-up paddleboarding, and snorkeling, with the chance to spot various sea creatures in the clear waters.

Adjacent to the beach is the historic Q Station, formerly the North Head Quarantine Station, which operated from 1828 to 1984. Today, it offers guided tours that delve into the site's rich history, including its role in Australia's immigration past. The Boilerhouse Kitchen & Bar, located within the Q Station, provides a delightful dining experience with views over the beach.
