Sulphur Passage Park is situated in the northeast portion of Clayoquot Sound on the west coast of Vancouver Island. Known as the Upper Shelter area, the park is nestled between Flores Island and the Megin River watershed and encompasses Obstruction Island and coastal upland strips of Sulphur Passage and Shelter Inlet, a popular kayaking destination.
This undeveloped wilderness area is a great place to see wildlife, including whales and other marine mammals and a variety of birds. The park protects old-growth Sitka spruce forests, a fjord and an estuary. The estuary is a sensitive and biologically productive marine ecosystem. It supports large numbers of birds, fish and intertidal creatures. Access to this undeveloped park is by boat only.
