How does it feel when a monumental chunk of ice splits off a glacier and crashes into the sea? The sound is like thunder. The impact shoots water hundreds of feet into the air. You hold your breath as you catch the moment on film. Then you wait for it to happen again. And it does. Glacier Bay has more active calving glaciers than anywhere else in the world.

Cruise by Reid and Lamplugh glaciers to the mighty John Hopkins - surrounded by rugged peaks and sheltering a seal pupping ground. Linger at Grand Pacific and Margerie glaciers for the grandest spectacle of them all. Margerie is an Ice Age giant a mile wide and 25 stories high. You will marvel at nature's unrelenting power as you witness the birth of one massive iceberg after another.
Search for humpback whales returning from their wintering grounds near Hawaii, killer whales feeding in the park's near-shore waters, Steller sea lions resting on rocky islands, and harbor seals nurturing their pups. Glacier Bay is the setting for an unforgettable wildlife search. The highest concentration of tidewater glaciers on the planet can be found at Glacier Bay National Park and Preserve. Spread across an impressive 3.2 million acres in southeastern Alaska, this treasure trove of scenic coastal islands, narrow fjords and substantial wildlife offers an inspirational glimpse of what Mother Nature does best.
"Morning of Creation "
When John Muir discovered Glacier Bay in 1879, he surveyed the unblemished panorama and declared it "still in the morning of creation." Muir wasn't the first explorer to be in the area. Nearly a century earlier, George Vancouver's ships sailed right past it because a wall of ice sealed off the entrance to the bay. But over the last 200 years, the ice has been steadily receding, revealing a stark landscape that's slowly being taken over by vegetation that can't resist the fresh rock and soil. The result is a lush, temperate rainforest of spruces and hemlocks that carpets large portions of the stunning terrain.
Wildlife Protection
Glacier Bay, first set aside as a national monument by Calvin Coolidge in 1925, is managed by the National Park Service, which has the difficult job of protecting the wilderness, the whales, and the other wildlife while serving the huge public visiting the park. This rugged land the size of Connecticut cannot be seen by car, only by boat or plane, and the presence of too many boats threatens the wilderness experience and may disturb the wildlife. The whales appear to be sensitive to the noise of vessels and, since the 1970s, when only a single whale returned one year, the park service has used a permit system to limit the number of ships that can enter the bay.
As an alternative, consider the other places to see Alaska's glaciers and whales that are easier and less expensive to visit. If you're in Juneau, consider a day trip to Tracy Arm instead. In Southcentral Alaska, plan a day trip from Whittier to see the glaciers of western Prince William Sound or from Seward to see Kenai Fjords National Park. There are other places in Southeast rich with marine wildlife, as well. Still, Glacier Bay beats them all -- and just about anyplace on earth -- for the combination of lots of whales and lots of big glaciers.
