Also known as Dolomite Narrows, the waterway connects Juan Perez Sound with Skincuttle Inlet. Because of the high nutrient content in the water, the aquatic life is almost impossibly large and vibrant. At low tide it is possible to walk along the shore, but as this can't be done without treading on delicate life forms, it is discouraged. Killer whales, or orcas , are often sighted in the Juan Perez Sound region. Best time for whale watching is late spring and early summer.
Eagles are a common sight, as are dozens of other birds scattered about the islands.
A good place to go to is the Delkatla Wildlife Sanctuary near Masset, at the head of the Delkatla inlet. Sandhill cranes stop here in spring and fall on their migratory routes, and tundra swans stay for the winter. Another common resting spot for migrating birds is the Rose Spit Ecological Reserve in Naikoon Provincial Park. Fully one third of the province's sea lion population calls the Charlottes home. A large colony hauls up on Joseph Rocks, off the west coast of Graham Island, miles away from the nearest point of road access.
