Sydney Lower North Shore Dog Beaches: A Complete 2026 Guide
The dog friendly beaches in the Lower North Shore are my first thought when I picture the perfect afternoon with my dog Cinnamon. Forget the big, crashing surf of the ocean beaches, this area especially around Mosman and Clontarf is a treasure trove of sheltered harbour coves. The water is beautifully calm, the scenery is stunning, and the whole vibe is just wonderfully relaxed. These are our go-to spots for a gentle paddle, a shady picnic and a proper escape from the city hustle.

A Critical Safety Warning for the Area
The beautiful, leafy bushland that makes the Lower North Shore so stunning is also a prime habitat for a serious danger: paralysis ticks. Mosman and the surrounding suburbs are known hotspots. A single tick bite can be fatal for a dog. Please ensure your pet’s tick prevention is up-to-date, and always perform a thorough physical check of their entire body after every single visit to this area.
