If you haven’t read my Yellowstone Itinerary, be sure to go check that out! I didn’t go into a lot of detail regarding all the wildlife we saw, so I wanted to share more on that in this post.
What types of wildlife did we see during our time in Yellowstone?
- Bison
- Elk
- Grizzly Bears
- Big Horn Sheep
- Chipmunks
- White pelicans
While that may not seem like many animals, we were only in the park for two days. The likelihood of seeing some form of wildlife in Yellowstone is pretty high! Even driving through without making stops, you would be able to see buffalo or elk in the meadows from the roadway. We were so lucky to be in the right place at the right time to spot the two Grizzly Bears that we saw. Check out the photos below – we were across the river from the bears and you are required to stay 100 ft away so there wasn’t much I could do without a better camera lens to zoom in with.
Travel tip: Be sure to take along binoculars and a camera with good quality zoom capabilities. Since our trip, I’ve purchased a 75-300mm lens that will allow me to better capture these sightings!
