I took this tour on early July, the scenery was amazing! We saw a lot of wildlife in Yellowstone including BEAR and COYOTE! The best part is the Cabins we stay, give me the chance to enjoy the starry night inside the park, it's a lifetime experience.
Me and my family had a wonderful time with this trip. We only spent one night but we accomplished so many. We even get chance to do gondola scenic view + snow tubing on second day before the bus pick up back to San Francisco. I will definitely recommend this tour :)
