The Hypipamee crater is referred to as a volcanic pipe. The pipe was opened upward through surface rocks by gas produced from molten rock below and as a result of tremendous pressure, the vent exploded sending volcanic bombs far across the landscape. It has a diameter of 61 metres at the water level which is 58 metres below the platform. Even 85 metres below the water surface, the pipe hasn’t lost any of its dimensions.
Meander along a 800 metre return (30 minutes) rainforest track and emerge at the viewing platform overlooking the sheer granite walls of the crater.
