For our first trip to the area, we hired Teton Excursions for a private guided tour in two days, one day at the Tetons and the second day at the lower loop of Yellowstone National Park. Aaron picked us up in Jackson in a clean, comfortable van and had breakfast, lunch, snacks, and drinks for us. Aaron knew all the spots to see wildlife, the history, the best views, the stories, the hikes, the restrooms, and how to get through the traffic and parking. He adapted the tour to our interests. I highly recommend Teton Excursions as a guide if you want to make the most of your trip. Carrie T., Austin, Tx
