We found this tour based on TripAdvisor reviews and it did not disappoint. Our tour guide was Will and boy does he know his stuff- about Colorado history, wildlife, geology, you name it. He was super chill and very flexible with catering to the group, like when we wanted some coffee we just walked on down the road during a bathroom break and he picked us up from there. If we saw wildlife on the road he would pull over so we could get down and check it out. Made it really easy to hit all the good spots without having to rent a car and navigate the park yourself. I would definitely take another tour through this company again, or even book this same one in the future, it was that cool.
