Marine Mammal Viewing

Alaska’s marine mammals range from ocean-dwelling creatures, like whales, to those dependent on the oceans for food, like polar bears. To learn more about these animals and where to see them, click on the links below. Be sure to check back as we continue to build the website and add more animals to the list.

To reduce the potential for harm to marine mammals, familiarize yourself with the guidelines and regulations concerning marine mammal viewing.

Polar Bears

Hundreds of thousands of years ago, Ursus maritimus, or the sea bear, evolved from its brown bear (Ursus arctos) ancestors to occupy an ecological niche in the frozen far north. Its white coat, made of water repellant hair on top of a dense undercoat, serves as camouflage and acts to reflect sunlight to the bears black skin. Its large paddle-like feet, with their fur covered pads, are well suited for swimming and for dispersing the weight of the bear when hunting on ice for ringed seal and other prey.


Nineteen polar bear sub-populations can be found throughout the Arctic. While the status of some sub-populations of polar bears is well documented, that of several others is unknown; the world-wide population estimate of the total number of polar bears is thought to range between 20,000 and 25,000 bears. Two polar bear sub-populations exist within the United States including the Southern Beaufort Sea sub-population (900 bears, Bromaghin et al. 2015) and the Chukchi/Bering Sea sub-population (population estimate unavailable). The IUCN/SSC Polar Bear Specialist Group currently lists the Southern Beaufort Sea sub-population as declining; the trend for the Chukchi/Bering seas sub-population is unknown (see Climate change, contamination of the Arctic environment, potential over-harvest, and increasing human development in polar bear habitat pose conservation challenges for polar bears. The polar bear is listed as threatened throughout its range under the federal Endangered Species Act (ESA) due to projected losses of sea ice in the next 50 years.


Two Alaska communities, Kaktovik and Utqiagvik (formerly called Barrow), offer limited opportunities for polar bear viewing.

Though polar bears spend most of their lives on the sea ice, many gather during the ice-free period between August and October along the coast near Barter Island where the village of Kaktovik is located. The bears generally rest on barrier islands, but also venture near the village to feed on the remains of hunter-harvested bowhead whales.

Kaktovik is a small Inupiat village with a very limited number of hotel rooms, vehicle rentals, and few other visitor amenities. Access is by small commercial or chartered aircraft and weather-related delays are common. Most visitors come to view bears in September.

Barter Island lies within the Arctic National Wildlife Refuge (Refuge), a land unit of the U.S. Fish and Wildlife Service (USFWS). The USFWS Marine Mammals Management office, which manages polar bears in the United States, worked with the Refuge to develop a commercial guided polar bear viewing program that meets the requirements of the Marine Mammal Protection Act and the Endangered Species Act. The Refuge does not have jurisdiction over lands on which the bowhead remains are located; however, activities there must still conform to the Marine Mammal Protection Act and Endangered Species Act.

Visitors viewing polar bears near Kaktovik and on Refuge waters have increased exponentially since 2011. Now, bears and viewers gather around the village even as critical subsistence activities occur, increasing the potential for conflict. The Refuge is dedicated to providing quality polar bear viewing opportunities that minimize threats to public safety, potential disturbance to polar bears, and conflicts with local residents.

To ensure federal laws protecting polar bears are met, Kaktovik and the Refuge recommend viewing polar bears with a guide. Even with a guide, individuals must ensure their activities around polar bears are safe and lawful. Guides permitted to conduct polar bear viewing on the Refuge have shown proof that they meet all applicable federal and state regulations. Guides may have additional requirements set by municipal governments. Make sure your guide is operating legally and has a safety plan you can review.

Farther west on Alaska's northernmost tip, Utqiagvik also offers polar bear viewing possibilities, though the chances of seeing a bear are not assured. Check with local hotels for information about guided tours.

The North Slope Borough's Department of Wildlife Management has posted information on polar bear safety, research, and subsistence hunting on the North Slope Borough website.

If you are visiting Utqiagvik and plan on leaving the city to view wildlife, whether polar bears, caribou, or birds, be advised that most of the surrounding lands are owned by the local Alaska Native Corporation, Ukpeagvik Iñupiat Corporation. Check with UIC before you leave to see if you will need to obtain a land use permit. Contact: UIC Land chief Delbert Rexford at (907)852-7462 or

Polar bears are hunted for subsistence in Kaktovik, Utqiagvik, and throughout coastal Alaska by Native hunters. Harvest levels are managed through international agreements and treaties with cooperation by the local communities and the USFWS. The Marine Mammal Protection Act of 1972 and the ESA provide for the legal harvest of polar bears as well as other marine mammal species by Alaska Natives. Please be respectful and do not disturb any subsistence hunters encountered during your viewing activities.

Arctic Refuge website includes Polar Bear Source Book (5.8 mb PDF) outlining legal requirements and stewardship obligations while viewing polar bears, including safety guidelines designed to help visitors minimize polar bear-human interactions and maximize the safety of both humans and bears.
