Our guide was Grant and he made sure our experience was a memorable one. The tour was extremely well done, with everything done exactly as the website described so our expectations were realistic and were met. Grant is super knowledgeable and passionate and took us places we would never have known about on our own. We saw a mother moose and her calf, many bison, some mule deer, elk (who bugled) and spectacular scenery! We spent more than 12 hours and never stopped learning about the Park's history and its inhabitants. Thank you Grant!
