I cannot say enough great things about this tour. Yellowstone speaks for itself, however, our Guide Luke was truly amazing. Pleasant, knowledgeable and took such good care of my Sister and I. We never dreamed we would see so much wildlife, but Luke knew right where to go. From bears to beavers, the mysterious geysers and a great picnic lunch - WONDERFUL. Highly recommend this tour AND LUKE. You will be glad you did. Excellent!!!!
