Hiking and Wildlife Watching in Yellowstone

Hiking and Wildlife Watching in Yellowstone

Yellowstone National Park occupies a special place in the American imagination. Spread across over two million acres of mountains, grasslands, forests, rivers, and valleys, this pristine pocket of living, breathing Earth is a symbol of our connection to the natural world.

For hikers and nature lovers looking to enjoy the park at a deeper level, a weeklong adventure in the Yellowstone wilderness has all the makings of a perfect science field trip. Join to learn about the park’s unique geology, observe wild animals in their natural habitat, and attend seasonal lectures by local experts.

Welcome to the land of geysers and grizzlies

The Greater Yellowstone Area is home to 400 animal species, 10,000 hydrothermal features and over 900 miles of hiking trails. To see all the sights and species, you’d need a lifetime.

But with the help of local naturalist guides who know the park inside out (and how to beat the crowds), you’ll gain unprecedented access to one of Earth’s richest ecosystems—discover secret spots where hard-to-find animals congregate and marvel at the miracles of the Yellowstone Supervolcano.

From gushing waters to glorious wildlife


You’ve seen photos of majestic herds of bison grazing by the river and wish to witness it with your own eyes. But how do you approach wild animals without disturbing them? The answer: you don’t have to!

Thanks to your guides’ high-quality Swarovski and Vortex spotting scopes, you can observe even the hungriest wolves and the stealthiest foxes from a safe distance. With long-range optics and expert knowledge of animal behavior, no critter is off limits. You’ll be seeing the Yellowstone others don’t.

Did you know that this is one of the last preserved temperate ecosystems on Earth? Or that Native Americans have been inhabiting the region for over 11,000 years? And have you heard of the two gigantic magma chambers lying beneath the park’s surface?

Put simply, there’s the Yellowstone you think you know—and the one your guides will show you.

Every evening, a local expert will hold a lecture on a particular topic related to the park. The scientist in you will be giddy with glee to learn about the oldest bison herd in the US, migratory patterns of gray owls, or how the Yellowstone Caldera formed the area’s unique topography.

And let’s not forget the classics. No trip to Yellowstone is complete without a visit to the Grand Prismatic Spring, Old Faithful or the Grand Canyon. You’ll get to see them all—and much more.

Choose your activities during these six days and immerse yourself in the fascinating shapes, colors, sights and sounds of America’s first national park. Follow well-worn bison trails through flower-strewn meadows, see the cultural sites of the land’s indigenous tribes, or take a flatwater float trip on the Yellowstone River. Every trip is a completely new experience.

Meet the animals of Yellowstone National Park

Yellowstone’s diverse wildlife is as famous as its hot springs and geysers. Your guides will take you to the most interesting corners of the park and show you species you otherwise wouldn’t have access to. There are some species you can expect to find:


Bison have continuously inhabited the Yellowstone area since prehistoric times. A century ago, this ancient herd faced certain extinction due to extensive poaching, but thanks to the efforts of park employees, their numbers have grown from a meager two dozen to over 5,000 free-ranging bison.


Yellowstone is home to two famous species of bears: black bears and grizzly bears. The black bear is commonly found all over North America and is usually smaller and less aggressive. The grizzly bear inhabits a few isolated locations in the lower 48 and can be recognized by the pronounced hump between its shoulders.


Elk are the most commonly found large mammals in Yellowstone. Currently, there are between 10,000-20,000 living in the Greater Yellowstone Ecosystem. Only males have antlers, which they shed in spring. They immediately start growing again, reaching up to 30 pounds per pair.


After going extinct in 1926, wolves were reintroduced into Yellowstone in the mid-1990s. Their most common prey are elk and bison. Currently, around 100 wolves live in the park. Their return to Yellowstone has brought about an increase in beaver population and the recovery of vegetation such as willow and aspen.


Although small in stature, beavers are one of the most influential species inhabiting the Yellowstone wilderness. They are responsible for diverting streams and cutting down trees, which leads to changes in habitat structures. There are over 100 colonies living in the park.


Celebrated as the national symbol of the United States, the bald eagle can be found perched above the lakes and rivers of Yellowstone, hunting for fish below. Their population decreased dramatically in the 1900s, but since 2007 bald eagles have been removed from the list of endangered species.


Named after the large, curved horns belonging to males, bighorn sheep are mainly found in the northern part of Yellowstone National Park. They frequently display their athleticism on steep, rocky terrain and provide entertainment for onlookers with loud clangs of clashing horns during fights.


Moose are the largest members of the deer family. They’re usually found in the forested areas and willow flats in the southwestern corner of Yellowstone and near certain creeks and rivers. In recent years, fires and competition in the form of elk and bison have led to a decrease in their population.

A carefree week in the wild

This Yellowstone adventure changes every season—with different itineraries, animals and lectures available—but the high level of comfort you get always stays the same. You’ll be staying at a cozy lodge in Gardiner, MT, located near the northern entrance to the park.

Enjoy a variety of activities with your group, such as fishing, volleyball or reading by the river. During your entire stay, you won’t have to worry about meals, transportation, permits or fees. Your guides will handle the logistics and make sure you enjoy your experience to the fullest.

My wife and I spent five days with Cara In Yellowstone National Park. One day was better than the next. Wolves going in dens, black bears chasing siblings up a tree, coyotes and foxes searching for food, a bison traffic jam, and grizzlies 20 yards away are just a few of the many highlights of the natural wonders that we were in complete awe of. Cara’s knowledge, enthusiasm, and extensive knowledge were simply contagious.The equipment she used was top notch. Her passion for the animals we witnessed made the trip so worthwhile. Her easy going demeanor made conversation easy and informative. Every person we came in contact with in the park spoke highly regarding Cara’s stellar reputation as a wildlife guide, and she truly surpassed our highest of expectations going into the trip. Her ability to spot wildlife is no less than remarkable (and I thought I had good eyesight!) The only way to truly experience the Serengeti we witnessed in Yellowstone National Park is to take Cara from In Our Nature Guiding Services and be prepared to be surprised, excited, and truly inspired. I am in the process of booking my trip with Cara for next year. Her indelible impact on our excursions is one we are both thankful and appreciative of.
