Oyster Stacks

Oyster Stacks is a well-known shallow snorkel site within Cape Range National Park, named for five oyster-encrusted rock islets that protrude from the shallow lagoon reef close to shore.

Overview

Oyster Stacks lies within a narrow section of the Ningaloo lagoon where the outer reef is unusually close to the beach — about 300 metres — and the water is so clear and shallow (1–3 metres at high tide) that snorkellers can observe reef life in exceptional detail from the surface. The oyster-encrusted rock formations create crevices and overhangs that shelter a concentrated array of marine life: tropical reef fish, sea turtles (confirmed at the site), and blue-spotted stingrays on the sandy patches between coral structures.

Tidal access is essential: the site should only be visited at high tide (minimum 1.2 metres) to ensure enough water over the reef. Entry involves stepping off a rocky shore ledge — there is no sandy beach access from the car park — and the rocky substrate carries sharp oyster shells, so footwear or dive booties are strongly recommended until in the water. A tidal current can develop here; check conditions before entry.

The site is primarily a snorkel destination; no scuba operator lists guided dives at Oyster Stacks.
