8 of us had an amazing time doing a full day Yellowstone tour and also a Sunrise Teton tour. Our guide, Shaun, was amazing. He was personable, knowledgeable, and awesome with our kids. The Yellowstone tour was focused on geologic features but we saw our fair share of animals which was great. We saw moose, grizzly bear, elk, deer, a great grey owl, pronghorn, coyotes, wolves, bison and numerous others. Old Faithful was very cool as well. Shaun timed it perfectly so we could check out some scenery near Old Faithful. The Teton tour was also excellent. We were able to get close to the animals to easily see them through binoculars. Overall, so worth the money for this tour. They really do provide everything you need for an amazing day. It was also great having the same guide on both tours. They are able to tailor the tour to what you really what to see. We all love Jackson and both parks. Eco Tours is really a great way to see everything you want if you are in a time crunch and don’t want to do self guided. I think having a guide gets you some great opportunities you maybe don’t have on your own. Especially for those of us who appreciate nature but don’t necessarily have a ton of knowledge and experience. And again, if you get a chance to tour with Shaun consider yourself very fortunate.
