Access to tracks going most of the way around the lagoon on the inside of the crater from the end of St Peters St, Arahia St, Exmouth Rd and The Warehouse Way.
Stay on tracks. Do not attempt to circumnavigate the crater as to get across the entrance channel requires walking on the edge of the motorway bridge. This is illegal and you can be fined.
Tracks on north and east side are grassed and can be wet in winter. Tracks on north and west side are concreted. Main access is from St Peters St where there are information panels and a viewing terrace.
