We booked a full day private tour to Yellowstone last week with our guide Michael. We had the best time and saw so much wildlife! Up close and personal with lots of Bison (or Buffalo), bull moose and cow moose, huge elk bull and cow, beaver. Saw a black bear through binoculars. Michael really tried to look for 399 as she was spotted earlier that day but we couldn't find her. Left at 7am and got back at 7pm. Saw Old faithful, prismatic, geothermal pools, Yellowstone canyon. Had a nice lunch by the river. Michael knew lots about the area and park and was very interesting. Everyone enjoyed it - Couldn't have had a better day!!
