About
Glacier Bay National Park and Preserve is located in southeastern Alaska along the Gulf of Alaska, west of Juneau. Established as a national monument in 1925 and redesignated as a national park and preserve in 1980, the protected area encompasses approximately 5,130 square miles (13,287 sq km).
The park forms part of the vast Kluane/Wrangell-St. Elias/Glacier Bay/Tatshenshini-Alsek international protected area complex, one of the largest protected wilderness regions on Earth. Glacier Bay preserves a spectacular landscape of glaciers, fjords, mountains, forests, and marine ecosystems that showcase some of the most dramatic examples of glacial change in the world.
The park is best known for its magnificent tidewater glaciers and breathtaking fjord scenery. Visitors are drawn to towering walls of ice that descend from snow-covered mountains directly into the sea. Among the most famous glaciers are Margerie Glacier and Johns Hopkins Glacier, where massive icebergs regularly calve into the bay.
Cruise ships, tour vessels, kayakers, and wilderness travelers come to witness these natural spectacles and experience one of the world’s most pristine coastal environments. Wildlife viewing, sea kayaking, hiking, boating, photography, and backcountry exploration are among the park’s most popular activities.
Geographically, Glacier Bay National Park encompasses a vast network of fjords carved by glaciers over thousands of years. The landscape includes rugged coastal mountains, active glaciers, icefields, temperate rainforests, alpine tundra, rivers, and marine waters. More than 1,000 glaciers are found within the park and preserve, many flowing from the massive Juneau Icefield.
Elevations range from sea level to peaks exceeding 15,000 feet (4,600 m). The region’s maritime climate brings abundant precipitation, supporting lush forests of Sitka spruce and western hemlock at lower elevations while snow and ice dominate the high mountains.
Wildlife within Glacier Bay National Park is exceptionally diverse. Marine mammals are among the park’s most celebrated inhabitants, including humpback whales, orcas, harbor seals, Steller sea lions, sea otters, and porpoises. On land, visitors may encounter brown bears, black bears, wolves, moose, mountain goats, and Sitka black-tailed deer.
Birdlife is equally impressive, with bald eagles, puffins, murres, kittiwakes, marbled murrelets, and numerous migratory seabirds inhabiting the region. The park’s waters support abundant salmon, halibut, and other marine species, while newly exposed landscapes created by retreating glaciers provide valuable opportunities to study ecological succession.
Glacier Bay National Park and Preserve plays a critical role in protecting one of the world’s most important glacial and coastal ecosystems. The park serves as a living laboratory where scientists study glacier dynamics, climate change, and ecosystem development. Its conservation significance is often compared to Fiordland National Park and Kenai Fjords National Park because of its dramatic fjords, active glaciers, and extraordinary biodiversity.
Through its immense icefields, calving glaciers, thriving wildlife populations, and pristine wilderness, Glacier Bay National Park and Preserve stands as one of America’s most awe-inspiring natural treasures and one of the finest examples of glacial landscapes on Earth.

The majority of Glacier Bay is admired and experienced from smaller watercraft tours. The more adventurous may go mountaineering into the park, but this is not really on marked trails. Bartlett Cove has the only three maintained trails in the park.
Park Protection
Glacier Bay National Park was created to protect one of the world’s most spectacular glacial landscapes, where massive tidewater glaciers, rugged mountains, temperate rainforests, and rich marine ecosystems meet. The park provides habitat for several species of conservation concern, including humpback whales, Steller sea lions, marbled murrelets, and the threatened northern sea otter. Its waters support abundant marine life, while coastal forests and alpine environments sustain bears, wolves, mountain goats, and moose.
The park is internationally significant for protecting active glacial processes and one of the best natural laboratories for studying ecosystem recovery following glacial retreat. Glacier Bay contains some of the world’s most accessible tidewater glaciers and showcases dramatic ecological succession. Together, Glacier Bay National Park safeguards extraordinary glacial landscapes, productive marine ecosystems, and an unparalleled record of environmental change and recovery.
