Glacier Bay National Park

Log in to track your visit to Glacier Bay National Park.

Glacier Bay National Park and Preserve occupies 3.3 million acres of southeastern Alaska, protecting one of the most dramatic glacial landscapes on Earth and earning UNESCO World Heritage status in 1992. What makes Glacier Bay uniquely compelling is not just its grandeur but its geological youth — as recently as 1750, the entire bay was buried under a massive glacier more than 4,000 feet thick and 20 miles wide. By the time John Muir arrived in 1880, the ice had retreated nearly 40 miles, and today it has pulled back more than 65 miles, creating a living laboratory for scientists studying ecological succession. Sixteen tidewater glaciers still calve thundering icebergs directly into the bay, including the awe-inspiring Margerie and Grand Pacific Glaciers at the bay's northwestern reach. The park is accessible only by boat or floatplane — there are no roads connecting it to the outside world — which keeps the crowds manageable and the wilderness feeling vast and genuine. Cruise ships entering Icy Strait from Juneau carry most visitors into the park, while sea kayakers and backcountry adventurers experience the park in a far more intimate, self-powered way.

Because there are no roads into the park's wilderness core, the primary modes of exploration are boat, kayak, and floatplane. Day cruise and tour boats depart Bartlett Cove — the park's only developed area — and travel up-bay to the glacier faces, narrated by National Park Service rangers who explain the geology, ecology, and natural history unfolding on all sides. The journey to Margerie Glacier, where 250-foot walls of blue ice regularly send city-block-sized chunks crashing into the water, is one of the great boat rides on the planet. Sea kayaking is the definitive backcountry experience: paddlers can be dropped by water taxi at remote inlets and spend days working through a landscape of icebergs, waterfalls, and wildlife-rich coves with no other humans in sight. Bartlett Cove itself has a short network of forest trails, including the 1.5-mile Bartlett River Trail and the Bartlett Lake Trail, both threading through Sitka spruce and hemlock rainforest. Fishing for halibut, Dungeness crab, and salmon is excellent throughout the bay, and sport fishing charters operate out of Gustavus. Wildlife watching — whether from a kayak cockpit or a ship's rail — is rewarding at virtually every hour of the day, with humpback whales often feeding just offshore and brown bears patrolling the tide flats.

Glacier Bay's marine and terrestrial wildlife is extraordinary. Humpback whales arrive each summer to feed on the nutrient-rich waters, lunging through schools of krill and small fish just yards from tour boats. Orcas patrol the bay in resident and transient pods. Harbor porpoise and Dall's porpoise race boat wakes. Sea otters, reintroduced after near-extinction by the fur trade, wrap themselves in kelp to sleep just offshore. Brown (grizzly) bears roam the tide flats hunting for clams, sedge grass, and spawning salmon. Mountain goats pick impossibly steep routes across rocky cliff faces. The bird life is equally spectacular: tufted puffins, pigeon guillemots, Steller's jays, and bald eagles are all regulars, while the outwash flats serve as critical shorebird habitat during migration.

Glacier Bay is open year-round but the vast majority of services, including Bartlett Cove lodging (Glacier Bay Lodge), restaurant, park ranger programs, and kayak rentals, operate only from late May through early September. Day cruise tours sell out well in advance during peak season — book as early as possible. The park requires cruise ships to obtain a permit, limiting vessel numbers and preserving the experience. Most visitors reach the park through Juneau (59 miles southeast) via Alaska Airlines. The small community of Gustavus, adjacent to the park, has lodges, a small store, and air taxi services.

Glacier Bay has no road access. The gateway is Gustavus, Alaska, served by Alaska Airlines jets from Juneau (20-minute flight) and by small air taxis from multiple Southeast Alaska communities. Alaska Marine Highway ferry service connects Gustavus to Juneau and other Southeast Alaska ports several times a week in summer. From Gustavus, Bartlett Cove is a 10-minute drive. Cruise ships enter the bay directly through Icy Strait without docking at Gustavus.

Reserve a spot on the park's day cruise boat early — it is the only concessionaire-operated boat in the park and sells out by spring. Dress in waterproof layers even in July: weather shifts from sunny to cold rain quickly, and wind off the glaciers adds a significant chill. Bear canisters are required for all backcountry camping. If kayaking independently, get a thorough tidal briefing from the Visitor Center before launching — currents and calving ice create serious hazards. Mosquitoes are intense in forested areas near Bartlett Cove; bring strong repellent.
