Little Armstrong Bay

A gentle cove to relax and reflect

Little Armstrong Bay is one of Wadjemup / Rottnest Island’s quieter bays. Rocky outcrops on both sides of the bay embrace a short stretch of beach, making it feel all the more secluded. These serve to protect the shallow waters from the southerly and easterly winds, making it a calm, relaxing spot for families with young children.

But while the perfect place to relax and unwind, there’s still plenty of adventure to be had. Excellent snorkelling conditions can be found further out into the bay, and the Karlinyah Bidi makes its northwestern pass right by the bay, providing the ideal place to take a break from hiking and enjoy the cooling turquoise water.

Where to find Little Armstrong Bay


On the northern coast of Wadjemup / Rottnest Island, you can get to Little Armstrong Bay by jumping on the Quokka Coaches Island Explorer and getting off at Stop 17. Alternatively, hop on a bike and take the 12-minute ride — perfect for drying off after a swim.



Family-friendly snorkelling

You’ll find Little Armstrong Bay in one of Wadjemup’s five marine sanctuary zones, making it a safe haven for marine life. 

With shallower waters, it’s ideal for beginners, with deeper waters further out in the bay welcoming more experienced divers. Diving under the water and swimming out through a maze of seagrass, the natural reef creates a home for an amazing array of colourful and curious fish. And thanks to its protection, you may even come face-to-face with some species of sea life that aren’t found anywhere else along the island’s coastline.
