Alaska shore excursions have a habit of shocking Caribbean cruisers. A helicopter-and-dogsled combo on a glacier runs upwards of $700 per person, a fishing charter tops $400, and the famous White Pass and Yukon Route scenic railway starts north of $150 for a few hours aboard. Prices are high because Alaska is remote, part of the U.S. (with its wages and insurance costs), and many tours need helicopters, seaplanes or specialist boats.

The good news: nearly every port has a solid lineup of free or very cheap things to do on your own, no tour bus required.

Skagway is a gold-rush theme park you can explore for nothing. Klondike Gold Rush National Historical Park runs four free museums, including the Moore House (Victorian rooms from the town's first family) and the Mascot Saloon. Trailheads to Upper and Lower Dewey Lake, Reid Falls and Gold Rush Cemetery are all walkable from the ship. Fancy a drink with your history? The Red Onion Saloon, once a bordello, does a $20 'Quickie Tour' of its supposedly haunted brothel museum.

In Juneau, skip the $60 Goldbelt tram day pass and hike the Mount Roberts Trail instead — steep and often muddy, and make noise for bears — with a free Tlingit film at the top (note: the tram has been closed for maintenance since late April 2026, so check before you plan). You can still watch Tlingit artists carve and dance for free at the tram base. Downtown, the Juneau Voices audio installations at 11 spots make a self-guided walking tour free. Museums are affordable too: Juneau-Douglas City Museum ($7), Alaska State Museum ($14) and the Sealaska Heritage Institute's Walter Soboleff Building ($10).

Ketchikan's Creek Street boardwalk, built over salmon-filled Ketchikan Creek, costs nothing to stroll; Dolly's House, a former red-light home, is $10. The Tongass Historical Museum and Totem Heritage Center are $6 each (or $9 combined), and the 1.5-mile Salmon Walk links it all. Independent types can reach Saxman Native Village, 2 miles south, by city bus and pay just $5 to see 25 replica totem poles and working carvers.

At Icy Strait Point, the Hoonah Packing Co. cannery museum is free and a $20 tribal dance show is the budget pick, while Sitka pairs the free Sitka National Historical Park with the $17 Alaska Raptor Center. Haines offers free self-guided walks and the American Bald Eagle Foundation for $25.

The smart play: mix one big splurge excursion per sailing with independent days in between. Check opening hours and seasonal access before you go, pack layers for temperamental weather, and download any walking-tour info while you still have ship wifi. Cruise lines won't advertise these options, but the locals are happy you asked.
