The Shark Bay tourism guide lists Bar Flats as a popular boat-accessible dive and snorkel site in about 3 m, with corals, fish, tubeworms, sponges and occasionally dugongs. Shark Bay holds one of the world's largest dugong populations (around 10,000 animals) in its vast seagrass meadows, so a sighting is a genuine possibility. The site is shallow and easy, but needs a boat and local knowledge.

No further published detail was found.

Bar Flats is reached by boat from Denham or Monkey Mia; the location is known to local skippers. Anchor in sand clear of coral.

Shark Bay is dominated by strong southerly winds, which blow most days from about October to March and often exceed 20 knots by late morning; the calmest conditions are in April-June and on early mornings. The inner bay is shallow and well protected from ocean swell, but the western shores of Dirk Hartog Island and Steep Point face the full Indian Ocean. Water is 17-19°C in winter and 23-26°C in summer.

Shallow flats become choppy and turbid in the afternoon southerly.

Anchor in sand, snorkel or dive over the corals and tubeworm beds in 3 m, watching for dugongs over the seagrass edge.

No scheduled dive operator; private boats and occasional charter/tour boats.
