Hells Gates is the name of the mouth of Macquarie Harbour on the West Coast of Tasmania. It is a notoriously shallow and dangerous channel entrance to the harbour. The actual channel is between Macquarie Heads on the west and Entrance Island on the east (the main length of the harbour runs southeast of Hells Gates). There is a wider area of water between Entrance Island and Macquarie Head, but it is too shallow to get a boat over.
