We had an enjoyable day with Sarah as our guide. She gives us enough information to make the visual experience interesting and seems to care deeply about the park and its fauna and flora. The early morning pick up at the hotel was timely and the pace was relaxing, with time for us to soak in the scenery and snap photos. Sarah managed to show us, bisons, bear, elks and bald eagle. I should also mention that Josh the owner answered every question we had about the tour timely. Highly recommended tour for a first time visit at Yellowstone.
