The Seymour Canal Cabin at the Tip of Seymour Canal, Admiralty Island
Oliver Inlet State Marine Park covers 560 acres on Admiralty Island, about 14 miles (straight line) south of Juneau. Its public-use cabin, the Seymour Canal Cabin, stands on saltwater at the tip of Seymour Canal. Alaska State Parks has a separate page about the Oliver Inlet tramway, with an interpretive panel installed in the park.
Alaska State Parks says Seymour Canal has the greatest known concentration of nesting bald eagles in the world. Seals, sea lions and whales use the canal throughout the year, and trumpeter and whistling swans and other migrating waterfowl rest along it. The area has one of the largest brown bear populations in Southeast Alaska, so use caution.
