The Coles Bay coastline offers a gentle introduction to snorkelling and diving in Tasmanian waters. The shallow, calm conditions make it forgiving for beginners, though visibility can vary depending on weather and swell. Along the reef and seagrass beds, keep an eye out for brightly coloured sponges clinging to the rocky substrate, wrasse picking through the kelp, and schools of sprats catching the light. The Cross-back Stingaree (a small, harmless ray) rests on sandy patches near the seagrass. Mussels and oysters are common throughout. Come prepared for cold water, as a wetsuit is essential year-round.
