Our family of 4 (including a 3 year old and 8 year old) booked two days of tours in early October of 2021, including a "best of Yellowstone" and "Wildlife Safari" tour. We had Derek as a tour guide for both days and he was wonderful. The first day included an overview and stops at the "best of" what the park had to offer. Yellowstone is huge and it is truly impossible to see everything, however Derek selected locations that served as the best examples of the features that the park had to offer, so by the end of the day we put eyes on all of the things that make the park special. A few of these include the Grand Canyon of Yellowstone, Mud Volcano (Dragon's mouth spring), Lake Yellowstone, many Geysers (including Old Faithful), paintpots and multiple other geothermal features. Derek's educational background and knowledge of the park was evident - he engaged in our love of learning and explained the history and science behind what we saw. I appreciated that he was able to relay the information on a level that even our 8 year old understood (and even our 3 year old at times). While the tour did include a good bit of driving, Derek used this time to describe the topographic/geographic changes we experienced during the drive and patiently answer ALL of our questions (and engage in our children's silly singing songs on repeat). He also had us out of the car as much as possible for short hikes - which allowed us to see a "hidden" waterfall and feel a mini-earthquake caused by the geothermal activity (and was just generally good for the kids' energy levels). Our second day was just as amazing if not more. We were up VERY early to try to experience as many animals as possible. We headed straight to the Hayden Valley and were so excited to see wolves! Given the small number of wolves in the park, this was a rare and phenomenal experience. Derek explained the history of the wolves in the park, their removal and then their reintroduction in the 1980's. This may have been our favorite memory of the two day tour. That same day we saw a black bear and two cubs (a bucket list item for the kids), multiple bison, elk, pronghorn, bighorn sheep, a bald eagle and others. Derek even drove around the "circle" in Mammoth Hot Springs about 10 times so my kids could see the Elk and hear their bellows before heading back to the hotel. The Company also provided gear that really made the viewing experience outstanding, including binoculars and high powered spotting scopes. Also to mention were the delicious lunches provided in the most beautiful settings each day. We would 100% do another tour with this group. Last, I appreciated that Derek conveyed to my children the need to respect both the animals and land forms in Yellowstone so it will be available for future decades and generations (and generally just the need to use common sense when in the park). Both of my kids say that their visit to Yellowstone was their favorite vacation ever (over Disney World, the Beach, NYC etc.) and my son still talks about our tour guide, Derek.
