Posted by YMT Vacations on Aug 31, 2021 9:56:24 AM

National Parks are the best place to see wildlife in USA. They offer protected habitats for wild animals to roam freely. Visitors can observe wildlife as they live and interact with each other in their natural environment.

The best wildlife viewing can be found at these National Parks.

Yellowstone National Park


America’s first national park, Yellowstone is located in Montana, Wyoming, and Idaho. The park is actually the largest active supervolcano in the United States. At 30-by-45 miles, it last erupted 640,000 years ago. No need to worry, though. Experts say there will be decades of warning signs before the next eruption.

Yellowstone National Park is home to many animals native to the Rocky Mountain region. The park’s abundant and diverse wildlife includes an estimated 300 species of birds, 16 types of fish, and 67 species of mammals. More than 4 million people visit the wildlife at Yellowstone each year.



Yellowstone is the only place in the U.S. where bison have lived continuously since prehistoric times. These powerful herbivores are the largest mammals in the park. Males weigh up to 2,000 pounds, while females weigh up to 1,000 pounds.

Bison still display wild behavior like their ancestors. They congregate during breeding season to compete for mates, and explore in search of new habitats.

Unlike other herds can be seen all year long in the Hayden and Lamar valleys.



Inhabited by both black bears and grizzly bears, Yellowstone is one of the best places to see wild bears. Black bears can be black, blond, or brown, but grizzlies tend to have a prominent shoulder hump. This is the best way to ID them. Additionally, grizzlies can get up to 700 pounds, while black bears are typically half that size.

Bears are active in Yellowstone during the spring, summer, and fall. They hibernate all winter, emerging again in March or early April. Visit Lamar and Hayden valleys for your best chance to spot bears.

Other Wildlife to Spot at Yellowstone National Park

A variety of wildlife is abundant throughout the park. During your visit, you’ll have a great chance of seeing the national park’s animals listed above. Additionally, these are some of the other animals you could see when visiting Yellowstone National Park:

  • Gray wolves
  • Wolverines

Denali National Park


This National Park was established to protect the immense wildlife population in Alaska. Offering beautiful scenery, fascinating wildlife and plenty to do, Denali made it on our list of National Park gems.

It is home to countless species of animals and is often compared to an African safari. Denali consists of 6 million acres and wild animals roam these unfenced lands, living as they have for ages.



Caribou belong to the deer family but are the only species in which both males and females grow antlers. They grow and shed their antlers each year.

Herds travel constantly and rely almost completely on their sense of smell to detect danger. They can run up to 40+ miles per hour and are excellent swimmers. Mature caribou stand about 8 feet in length and weigh anywhere between 130 to over 350 pounds.

There are about 2,000 Caribou in Denali. During the early summer, they can be seen in the open areas east of the Savage River. Later in the summer, they move west of Sable Pass. One particular herd, the Denali Herd, inhabits most of the park east of the Foraker River and north of the Alaska Range most of the year.

Other Denali National Park Wildlife

In addition to caribou, other large and small mammals that can be spotted in Denali National Park include:

  • Grizzly bears

In addition, there are plenty of recreational opportunities ranging from relaxed to very active. El Capitan is one of the most iconic summits in Yosemite and was the site of Alex Honnold’s free solo ascent in 2018.

Sierra Nevada Bighorn Sheep


These sheep are the rarest mountain sheep in North America. They are an endangered species because of their low numbers and vulnerability to disease. Yosemite offers the best habitat for bighorn sheep, because of the plentiful high elevation alpine meadows. It is an important source of nutrition for the bighorn sheep.

Visitors are most likely to view bighorn sheep in low elevation areas during the winter. The weather is less severe at lower elevations and food is more accessible. During the summer, they return to the highest elevation peaks of the Sierra Nevadas.

Glacier National Park


Located in Montana, Glacier National Park is unique because it straddles the Continental Divide. This is where opposing Pacific and Arctic air meet, causing extreme weather. Check the park’s website for weather alerts before departing for your tour.

You may recognize the stunning Going-to-the-Sun Road from the opening credits of the 1980 film, The Shining.

The park has 71 species of mammals, and there are plenty of opportunities for wildlife viewing. Glacier National Park offers guided day hikes, as well as backpacking trips lasting from one day to one week.



One of the largest land mammals in North America, elk sport a distinctive mane. Males can reach between 700 and 1,000 pounds and have a rack of antlers. Females usually weigh around 500-600 pounds and do not have antlers.

Mating season occurs between late August and December. Dominant males attract females by showing off their large antlers and sparring with competitors. The male’s bugle call is often heard during the mating season.

Elk remain at higher elevations during the summer and move to lower areas in the fall and winter. Look for them in the North Fork area, around Big Prairie. They can also be spotted most of the year in the Two Dog Flats area.

Mule Deer


Mule deer are the most commonly seen and photographed large mammal at Zion National Park. Males have elegant antlers, which start to grow in the spring and continue throughout the summer. By the fall’s mating season, the antlers are fully-grown and used to jostle other males to establish authority.

Mule deer can be seen during the cooler morning and evening hours. Find them near Zion Lodge and along the Virgin River at the bottom of Zion Canyon. They frequent these areas to drink, graze, and cool off from the summer heat.
