Deep Glen Bay is a dramatic, sheltered cove on the Forestier Peninsula, about 7 km northeast of Eaglehawk Neck in southeast Tasmania. Its star attraction is the North Wall — a sheer underwater drop-off plunging from the surface to 30 metres, then cascading into giant boulder slopes beyond 40 metres. Dense with colourful sponges, beautiful sea whips, and invertebrate life, the bay is a go-to fallback when exposed sites like The Sisters are blown out. Towering dolerite and granite cliffs frame the rugged shoreline above, while nutrient-rich southern waters deliver excellent visibility and the chance of encounters with New Zealand fur seals and weedy seadragons. This is cold, deep, temperate snorkelling that rewards preparation with a drysuit and torch.
