Glacier Bay: What 200 Years of Glacial Retreat Looks Like

In 1750, the entirety of what is now Glacier Bay was covered by a single vast glacier more than a kilometre thick. By the time George Vancouver sailed past the entrance in 1794, the ice had retreated 5 km. By 1879 when John Muir arrived, the bay had opened 77 km. Today the bay extends 105 km from the entrance and the glaciers continue to pull back. Nowhere else on the planet is it possible to observe a full successional sequence from bare rock to mature temperate rainforest compressed into such a small area, because here the land itself is progressively being revealed.

That geological fact is the reason Glacier Bay is worth the considerable effort and expense of reaching it. This is not a park you visit for hiking infrastructure or lodges or tourist amenities. You visit for the ice, the silence, and a sense of geological time that is genuinely humbling.

Getting There

Gustavus, Alaska is the gateway. There is no road. Access is by small plane from Juneau (about 20 minutes, daily flights on Alaska Airlines and small charter companies) or by private boat. The park is inaccessible by road of any kind.

Juneau itself is accessible from Seattle by Alaska Airlines (roughly 2 hours) or by the Alaska Marine Highway ferry system. Juneau is also a major cruise ship port, and many passengers take day excursions to Glacier Bay as part of a cruise itinerary. Cruising the bay takes most of a day from Gustavus.

Flights from Juneau to Gustavus cost around $150-200 return. The puddle-jumper aircraft are small (typically 9-19 seats) and can be cancelled in bad weather. Build an extra day into your schedule.

From Gustavus, the National Park visitor centre and Glacier Bay Lodge are about 10 km by road. The lodge operates a bus shuttle. No cars are available for hire; the lodge and local taxis are the transport options.

On the Water

The park is primarily experienced by boat. The main options:

Day boat tour from Glacier Bay Lodge: A full-day vessel trip up the bay to the active tidewater glaciers, including Margerie Glacier and Grand Pacific Glacier at the bay’s northwestern end, 105 km from the entrance. The boat departs around 07:30 and returns around 15:30. Cost approximately $225 per adult. This is the most accessible way to see the calving glaciers - Margerie Glacier is particularly active, with regular calving events that send car-sized chunks of ice crashing into the bay. National Park ranger naturalists accompany every trip.

Kayaking: The park is one of the premier sea kayaking destinations in North America. Kayak rentals are available from Glacier Bay Sea Kayaks. Independent paddlers can access the upper bay by using the lodge’s boat trip as a water taxi, being dropped and collected at specific locations. The upper bay (Muir Inlet and the Johns Hopkins area) sees very few visitors and has a wilderness quality that the day boat area doesn’t. Plan for 5-7 days if sea kayaking independently. Cold water, variable weather, and the need for tides and wind knowledge make this a trip for experienced paddlers. Water temperature year-round is around 4-8°C; a wetsuit or drysuit is non-negotiable.

Private charter: Several charter boats operate from Gustavus for groups wanting more flexibility than the scheduled day boat. Costs start around $1,500-2,000 per day for the vessel.

Wildlife

The bay sees humpback whales May through September - the park’s strict entry permit system (a limited number of vessels per day are allowed) keeps the bay quieter than most whale-watching areas, and sightings are very common on the day boat. Orcas visit periodically. Steller sea lions haul out on rocks throughout the bay. Brown bears are present on most shorelines; black bears in the forested areas near Gustavus.

Bird life: the tufted puffins nesting on rock faces in the lower bay are the most sought-after sighting. Marbled murrelets, Arctic terns, and a significant population of nesting bald eagles are all present.

June and July bring the most reliable weather (Gustavus averages 660mm of precipitation per year, mostly late summer through fall) but also the most visitors and highest prices. September has wetter weather and often excellent whale activity as humpbacks feed heavily before departing south.

Where to Stay and Eat

Glacier Bay Lodge is the only accommodation inside the park, operated by the National Park Service’s concessionaire. Rooms from around $350 per night in season. The dining room serves three meals a day and is the only sit-down restaurant in the park. The kitchen uses local salmon and halibut. Book early - the lodge has limited capacity and fills completely July through August.

Gustavus Inn in Gustavus village is the more comfortable and slightly cheaper option outside the park. From around $280 per night including breakfast and dinner. The Inn has been operated by the same family since 1965 and is a genuine Alaska homestead property. The evening meals using local fish, produce from the property’s garden, and local wild game are excellent.

Annie Mae Lodge in Gustavus is a smaller B&B option, from around $180 per night.

The village of Gustavus itself has a small store, a bakery, and a few rental cabins. It’s a community of around 450 people, largely off-grid and intentionally so. There are no fast food restaurants, no chain hotels, no tourist gift shops. This is not an accident.
