If you had never been to yellowstone before, like me and my wife, we highly recommend this tour. Our tour guide Alex was fun and very knowledgable of Yellowstone history. She made the trip really enjoyable, at a good pace for everyone, and she answered pretty much all the questions our group had. Overall, if you had to choose a hike from all the ones offered, I would hands down pick this one. The price is very reasonable and the 6-mile(ish) round loop gives you breathtaking views of the canyon and the falls. Many thanks to Alex for making our time in Yellowstone so memorable!
