Lake Bullen Merri is a spectacular volcanic maar crater lake near Camperdown in Victoria's Western District. Formed by ancient volcanic eruptions, this brackish-water lake reaches depths of 66 metres with shallow nearshore shelves dropping abruptly into deep, green-tinted waters. Its sheltered setting offers unique inland snorkelling away from ocean swell, with submerged volcanic walls and fascinating geology to explore. The lake is also popular with freedivers and technical divers seeking deep training dives accessible directly from the shore.
