Wildlife Chances on a Wildlife Tour

Spotting Moose, Elk, Bighorn Sheep, and Bears in Rocky Mountain National Park are common guest goals on our Estes Park Wildlife Tours. One of the most common questions I get regarding wildlife is "What can we expect to see on a Wildlife Tour?" Well, after two decades of guiding I have been able to compile some real statistics of what we see on wildlife based tours. If your tour is not a wildlife tour then your chances of seeing these animals is greatly reduced.

Bears in Rocky Mountain National Park

Many people expect all National Parks to be good places to see black bears, but bears in Rocky Mountain National Park are extremely rare sightings due to low berry options, high elevation and colder temperatures, and low carcass availibility due to lack of healthy apex predator populations like Grizzly and Wolves. Rocky's Black Bears enter hibernation in November and awaken from hibernation in April.

You do not need Bear Spray in Rocky Mountain National Park or bear bells. We do see Black Bears only a few times in May, and again in August and early September when the Choke cherries ripen. It is likely that more black bears live in the town of Estes Park than in the whole of Rocky Mountain National Park. I always like to joke that expecting to see a black bear in Rocky on any random day is like going to a Sushi resturant wanting to order a steak, it's just not the best place. Now if Elk, Moose, Bighorn Sheep, Yellow-bellied Marmots, or Pika get you excited then Rocky is one of thee best places to see them.

Wildlife Sighting Changes over the years

Some changes over the last decade worth sharing are Moose sightings have increased especially on the eastern side of the park with chances still low but possible in the Spring where before that was extremely rare. Sheep sightings have gone up year round. The Elk population has fallen by about 40% due to many factors, but are also migrating further east in the winter re-igniting traditional migration routes to and from the great plains. Coyote sightings have declined by a third likely due to the impact of the Wyoming Ground Squirrel population collapse in part due the 2013 floods, and fewer wintering elk.

*Currently Rocky Mountain National Park does not have Wolves or Grizzly Bears, though in the past we used to. Wolves have finally returned to Colorado as of late 2019 but none are living near Rocky yet!

If we target near Lake Estes. Nesting par at Lake Estes 2021 - 2023.

There is a large variety of other small mammals not mentioned here like Golden Mantled Ground Squirrels, Mountain Cottontails, Wyoming Ground Squirrels, Least Chipmunks, Colorado Chipmunk and various great birds that we see on a regular basis. We see them nearly every single day they are active.

There are a number of other species that do occur in Rocky Mountain National Park that we rarely see. Generally we only see these species a few times a year because they are nocturnal or avoid human activity. They include Pine Martins, Red Foxes, Pocket Gophers, various Bats, and Raccoons. If you are on a tour where you are lucky enough to see one of these animals then you have had a truly unique experience very few guests get to see.
