Our guide was Emma. She was fantastic. My sons, 17,13,and 10 had a blast. We saw wolf, grizzly, coyote, pronghorn, bison, elk, mountain goat, and mule deer. We saw them all before 9 am! We kept seeing animals after that and for pretty much the rest of the morning. The breakfast that Emma set out for us was huge. Way better than I expected. Emma was an expert and a true professional. She showed us all around the park, and didn't just focus on the animals. The highlight was watching a group of coyotes eating a bison kill in the Lamar valley. It was amazing.
