[2025 Hoonah-Angoon Attraction] Travel Guide for Glacier Bay National Park and Preserve (Updated May)

One of Alaska’s nicknames is “The Last Frontier,” and when you’re standing on the edge of a 15,000-foot cliff and gazing at the massive, ice-covered glaciers below, you’ll realize why the explorers of the past felt so strongly that they had reached the end of the world. It isn’t easy to climb the mountains of the Glacier Bay National Park and Preserve. Their terrain is difficult, and their weather is unpredictable. Some mountaineering expeditions can take a month or more. If you have the time, however, or if you’re just interested in views unlike any other, the Glacier Bay National Park and Preserve will provide an incredible experience for those who are adventurous enough to take it on. Address: Alaska, United States

Glacier Bay National Park Covering 3.3 million acres, Comprising rugged mountains, dynamic glaciers, temperate rainforests, wild coastlines, and deep fjords, Alaska's Inside Passage is a highlight. The park is also part of the World Natural Heritage. The estate covers 25 million acres and is one of the largest international protected areas in the world. The spectacular natural landscape is home to many grizzly bears, caribou and Dall sheep. It is home to the world's largest non-polar ice field.

Below is an introduction to Alaska's blue glaciers: Formation - Principles of Physical Optics: Over vast periods, glacial ice becomes highly compressed, reducing internal air bubbles and making it extremely dense. When light penetrates the ice, most wavelengths are absorbed, while shorter blue wavelengths are less readily absorbed and penetrate deeper, scattering and reflecting more, giving the glacier its blue hue. - Oxygen Enrichment: During glacier formation, accumulating snow compresses, gradually releasing gases like nitrogen. However, under immense pressure, oxygen bonds with ice crystals, forming structures similar to impurities in gemstones, also contributing to the blue color of glacial ice. Main Distribution Blue glaciers are scattered throughout Alaska's fjords and valleys. Glacier Bay National Park, Mendenhall Glacier, College Fjord, and Tracy Arm Fjord are all excellent locations for viewing blue glaciers. Famous Glaciers - Hubbard Glacier: North America's largest tidewater glacier, spanning 76 miles and reaching depths of 1,200 feet. Its highest point is equivalent to a 40-story building. It surges rapidly into the Gulf of Alaska, forming Yakutat Bay, an area rich in wildlife. - Spencer Glacier: Located deep in the Alaskan mountains. From Anchorage, travel to Whittier, then transfer to a train to reach the Spencer Glacier Whistle Stop. From there, a trail leads to Spencer Glacier. Viewing Methods - Cruise Tours: Cruises offer access deep into the fjords, providing close-up views of the magnificent blue glaciers, as well as witnessing dramatic events like calving and floating icebergs. - Helicopter Tours: Helicopter tours provide aerial perspectives of the blue glaciers, offering panoramic views of the entire glacier and its breathtaking intersection with mountains and ocean. - Hiking Expeditions: With professional guides, hike closer to the blue glaciers, experiencing their cold majesty firsthand. You can even touch the ice and observe its textures and structures.
