Whale watching from Juneau: when, where and what to book

The waters around Juneau are some of the best places in Alaska to see humpback whales. Many of them spend the summer feeding in the channels and bays north of town, often within sight of the mountains and the icefield.

When to go

Humpbacks are seen around Juneau through the whole summer tour season, from spring into autumn. Tours run most often from May to September, when cruise ships are in port.

Where tours leave from

Most whale-watching boats leave from Auke Bay, a harbor about 12 miles north of downtown and a short drive from the glacier. Tours usually include a bus transfer from downtown or the cruise docks.

What you might see

• Humpback whales, sometimes feeding together using nets of bubbles to trap fish
• Orcas, seen on some trips
• Steller sea lions hauled out on buoys and rocks
• Harbor seals, porpoises and bald eagles

How to choose a tour

• Boat size. Smaller boats feel closer to the water; larger boats are steadier and have more indoor seating.
• Length. Most trips spend two to three hours on the water.
• Sighting guarantee. Some operators offer a partial refund if no whales are seen. Check the terms.
• Combo tours. Many add a stop at Mendenhall Glacier, which is the easiest way to see both in one port day.

Responsible whale watching

Federal rules in Alaska require boats to stay at least 100 yards from humpback whales. Good operators follow the rules and turn off engines when whales are close, so the whales come to you.

What to bring

A warm, waterproof jacket, a hat and gloves, binoculars, and a camera with a zoom. It is colder on the water than on land, even in July.
