Board a small, expert-led vessel and glide deep into Stephens Passage — one of Southeast Alaska's richest humpback feeding grounds. With a professional naturalist and seasoned captain, this is the definitive bucket-list wildlife encounter in Alaska.
What to expect
You'll depart Juneau's waterfront aboard a purpose-fitted whale-watch vessel and transit into the open waters of Stephens Passage, where humpback whales congregate in extraordinary numbers to feed on herring. Your naturalist guide reads the water, spots blow spouts, and positions the boat for intimate encounters — often within yards of breaching and bubble-net feeding whales. Steller sea lions, Dall's porpoise, bald eagles, and harbor seals frequently join the spectacle. The small group means you're never fighting for a rail, and the guide answers every question in depth.
Good to know
Tours depart from the Juneau cruise terminal area and typically run 3.5–4 hours — well within all-aboard windows. Pre-book directly online as small-group spots sell weeks in advance, especially June–August. Dress in warm, waterproof layers regardless of forecast; the passage creates its own weather.
