Jurien Bay Marine Park offers easy shallow diving and snorkelling across reef and seagrass habitats, with depths staying between 1 and 6 metres throughout. Visibility is variable, so conditions can change, but the shallows make it manageable for beginners. The seagrass beds attract dugongs and turtles, while the reef holds western rock lobsters, octopus, cuttlefish, and lionfish. Australian sea lions occasionally pass through, and dolphins are spotted in the area. Between September and November and again in autumn, humpback whales move through the broader bay. Currents vary, so check conditions before entering, and watch for jellyfish and boat traffic near access points.

Visit in autumn or spring when visibility tends to be at its most cooperative and marine life activity picks up. If you're entering from shore, stay aware of boat traffic and give any sea lions or dugongs plenty of space.
The primary snorkeling sites, especially for sea lion tours around the islands like Essex Rocks and Boullanger Island, are accessed via boat tours departing from the Jurien Bay Boat Harbour. Some shore-based snorkeling is possible at locations like Sandy Cape and Dynamite Bay, though some areas may require a 4WD for access.
Sea lions are wild animals and can be unpredictable; regulations require snorkelers to maintain a minimum distance of 50 metres, though the animals may approach closer. Tour operators manage interactions. "Stingers" (jellyfish) may be present occasionally. Snakes can be present on beach paths during warmer months.
