Highly recommend this Excellent tour of Yellowstone and Grand Tetons with our guide Jeff of “Grizzly County Wildlife Adventures”, Jackson, Wyoming, on 12 Aug 2021. Our family of 5 (which includes a 4 year old) were very satisfied with our tour, ie. the “Yellowstone Private Tour”, which was a full day (11.5 hrs, which started promptly at 7am and we were back to hotel around 6:30pm) and included a nice lunch at a beautiful location alongside a river. Jeff was an excellent guide (12 years experience), who has an extraordinary wealth of knowledge about the parks, wildlife, and geology, and who brought along books, newspaper clippings, etc. to use as visual aides to help us understand the many different aspects of the park. He is well spoken and clearly explains the many aspects of the park. We learned a lot. Also, Jeff provided a tablecloth, real plates, and cloth napkins at lunch. Nice, personal touch! We saw a variety of wildlife, including a herd of bison that were crossing the road. We were able to stop and see these beautiful animals at a relatively close distance (30 ft). We never felt rushed. Jeff was always ready to help us with pictures and information. He would park the very comfortable and roomy van and join us for every stop with information and showing us the best places for pictures. It was so much fun, the adventure seemed to go by too quickly. I could go on, but suffice to say it was a great tour and Jeff was the reason it was exceptional! Thank you Jeff! GaryK, NY
