If you’re looking to see the most significant number of bears in one place in the United States, you don’t have to look any further than its national parks. With over 60 national parks spread throughout the U.S., each park is home to various wildlife and ecosystems, including many bears.

From grizzlies to black bears to polar bears, these majestic animals can live harmoniously with nature and their surroundings for 20-30 years.

Types of Bears in the USA

The United States is home to three main types of bears: black bears, grizzly bears, and polar bears.

Black bears are the smallest and the most widely distributed in the USA. They can be found throughout North America, from Alaska to Mexico. Black bears typically live in forests but can also inhabit open meadows, mountain slopes, and even urban areas. They can weigh up to 560 pounds and are omnivores, eating both plants and animals.

Grizzly Bears

Grizzly bears inhabit the western states of the US, including Alaska, Montana, Wyoming, Idaho, and Washington. They are brown or black in color and can weigh up to 800 pounds. They are omnivores but prefer a diet of fish, roots, berries, and nuts.

Polar Bears

Polar bears are the largest and most powerful of the three bear species. These magnificent creatures are white/cream-colored, can weigh up to 1,700 pounds, and are the only bear species considered marine mammals. Polar bears are found in the northernmost state of Alaska and Canada.

Polar bears have evolved to survive in frigid temperatures as low as -50 degrees Fahrenheit. They are carnivores, and their diet consists of seals, walruses, fish, and other marine animals.

Katmai National Park (Alaska)

Considered the final frontier of the United States, Alaska has the highest bear-to-human ratio in the USA, with nearly one bear for every five people in the state! The majority of the bears in North America live in Alaska. The highest concentration of grizzly bears in the United States is in Katmai National Park. The park was established in 1918 to protect the brown bears that frequent the area, and today it’s home to an estimated 2,000 grizzlies.

Visitors to the park can watch bears from a safe distance, with daily trips departing from nearby King Salmon. It’s an unforgettable experience to watch the majestic bears in their natural habitat.

According to the National Park Service, the annual visitation to Katmai National Park is around 40,000.

Best Time To Visit

The best time to visit Katmai National Park to look for bears is June to October. During these months, bears can often be seen fishing for salmon in the rivers and streams running through the park.

Safety And Precautions

Due to the area’s large population of grizzly bears, visitors must follow specific safety regulations. Failing to do so can result in a hefty fine or even jail time of up to six months. All visitors must watch bears from a safe distance and keep noise to a minimum. It is recommended that visitors carry bear spray and make sure to use it only in an emergency.

The national park with the most black bears is likely the safest place to view bears from a distance – and that is the Great Smoky Mountains National Park.

Visitors can spot black bears on guided tours and from a safe distance in the park. The peak season for bear-watching is from mid-April to early October. This is the time of year when the bears are most active.

Black bears in the Great Smoky Mountains National Park can be seen foraging for food, climbing trees, and sleeping in rocky crevices. They also roam for food, including berries, nuts, and insects.

Safety And Precautions

The park’s bears are relatively used to people, but visitors should still exercise caution. While black bears are much less territorial than grizzlies, they can still be aggressive if they feel threatened. Always stay at least 100 yards away, and never try to approach them. In case of an emergency, carry bear spray and know how to use it.

Arctic National Refuge (Alaska)

The Arctic National Wildlife Refuge in Alaska is home to the highest population of polar bears in the United States. The area is unique in its range of habitats, from the coastal plains to rolling hills and mountains. This variety of natural environments provides an ideal habitat for polar bears, which need a range of feeding grounds and areas to rest. The national park is also known for its spectacular ice and snowscapes, making it a perfect place to spot these amazing polar bears.

The Arctic National Wildlife Refuge is a huge area of 19.6 million acres, including parts of the Arctic tundra and boreal forest. The land’s diverse vegetation, including sedges and shrubs, provides a great food source for the polar bears. The national refuge is also one of the only protected parks in the USA where you can see all 3 types of bears. 

The area is also relatively untouched by human activity, meaning there is minimal competition for resources from other species.

Best Time To Visit

Polar bears are most active in the summer months when they gather in coastal areas to feed on salmon and other fish. In addition, they can also feast on seals during this time of year. During the winter, the bears migrate further inland and dive into snowbanks to escape the bitter cold.

Safety And Precautions

The U.S. Fish and Wildlife Service has designated polar bears as threatened under the Endangered Species Act. This designation is meant to protect the species from being hunted and to aid their recovery. The Arctic National Refuge is essential to this effort, providing the bears with a safe place to feed, rest, and raise their young.

Visitors can spot polar bears in the refuge from a safe distance. It is recommended that visitors stay at least 100 yards away and never approach the bears.
