About the Port
Sumner Strait threads through the Alexander Archipelago in Southeast Alaska, linking the waters near Wrangell and Petersburg to the wider network of channels that define the region's coastline. Framed by the dense old-growth forests of the Tongass National Forest, the strait offers passing views of steep, tree-covered slopes, quiet coves, and a shoreline largely untouched by development.
The waterway is prized for its wildlife, with humpback whales, orcas, sea lions, and bald eagles frequently spotted along its length. As a transit route rather than a docking point, travelers experience Sumner Strait primarily from the water, making open-deck viewing and naturalist commentary the best ways to appreciate its scenery. The surrounding islands and channels remain largely wild, offering a glimpse of Alaska's coastal wilderness far from any town or port infrastructure.
Pavlus Recommendations
How our planners would spend a day in Sumner Strait.
Post Up on Open Deck
Claim a rail spot early as the ship threads Sumner Strait; humpbacks and orcas often surface close enough to spot without binoculars. Morning and early evening light tend to bring calmer water and more activity.
Scan for Bald Eagles
Watch the tree line along the shore, where eagles perch on snags and soar over the channel. A zoom lens or shared binoculars from fellow passengers helps pick out nests in the old-growth canopy.
Join Naturalist Commentary
Onboard naturalists typically narrate the passage, pointing out wildlife, geological features, and Tongass forest ecology in real time. Check the day's schedule so you're on deck when the commentary begins.
