Glaciers currently occupy approximately 10 percent of the world’s total land area, but their existence is increasingly threatened by climate change. The important swaths of snow and ice aren’t just majestic remnants from the last Ice Age; they’re also ground zero for scientists struggling to understand just how quickly the Earth is warming. But because many glaciers are located in remote polar regions like Antarctica, Greenland, and the Canadian Arctic, visiting them isn’t exactly an individual endeavor (or for safety reasons, it shouldn’t be).

These expeditions in and near arctic areas get you close to some of the world’s most impressive glaciers for a full perspective on the Earth’s present—and future.

Antarctica

Luxury adventure company Abercrombie & Kent offers a 12-day “Classic Antarctica” expedition cruise led by a renowned team of environmental researchers and scientists, including Dr. James McClintock, director of the Antarctica Climate Change Project. Learn about Antarctica’s changing environment and efforts to conserve it while cruising the Drake Passage from South America’s southernmost tip toward the Antarctic Peninsula. Daily excursions include small boat iceberg and wildlife-spotting tours in the Antarctic Sound, South Shetland Islands, and Danco Coast, all with a focus on environmental conservation. From $12,995

Greenland

Silversea’s “Kangerlussuaq to Quebec City” voyage traverses 16 ports along the Arctic Sea from Greenland to Canada over the course of 14 days. Starting from Kangerlussuaq in western Greenland, the Silver Cloud vessel passes the Evigheds Glacier (the world’s second largest ice body after the Antarctic ice sheet), traveling south to Greenland’s capital, Nuuk, before crossing to the Canadian Arctic. Daily boat and land tours led by Silversea’s team of specialists take voyagers through remote Arctic islands and national parks in search of polar bears, walruses, and Atlantic puffins. With luck, on-board entertainment in the evenings might include a Northern Lights display. From $16,200

Norway

The “Intro to Spitsbergen: Fjords, Glaciers and Wildlife of Svalbard” voyage with Quark Expeditions promises plenty of Arctic glacier viewings—and it nearly guarantees polar bear sightings, too. This nine-day expedition focuses on the Svalbard archipelago. Located between mainland Norway and the North Pole, this area is known for its rugged tundra favored by polar bears, Svalbard reindeer, and Arctic foxes. For a peek at the equally abundant walrus population, take a kayaking excursion led by Quark’s expert team. These tours to the “wildlife capital of the Arctic” are wildlife friendly: The cruise line raises an average of $150,000 each season for the protection of polar environments and encourages guests to participate in a beach debris clean-up program on Spitsbergen trips. From $5,795

Argentina
Located on the Argentine side of Patagonia, Perito Moreno Glacier is one of South America’s most famous landscapes. The glacier’s icy walls tower approximately 240 feet above the blue waters of Lago Argentino in Los Glaciares National Park. For a chance to stand atop the mighty Perito Moreno and explore the glacier’s many caves, spend a few hours ice trekking on a “Big Ice Tour” with expert local guides from Hielo y Aventura. From $195

Canada
Spanning more than 15 miles across the Continental Divide on the boundaries of Alberta and British Columbia, Canada’s Columbia Icefield makes up the largest mass of ice in the Rocky Mountains.
