Grand Teton National Park owes its spectacular scenery to earthquakes. Boasting the youngest and steepest mountain range in the west, containing some of the oldest rocks on earth, featuring glaciers and glacier-carved lakes, abundant wildlife and a myriad of wildflowers, this park was almost lost to commercial development! As we guide you along the inner and outer loops of Teton Park Road, you'll hear from our impressive group of local experts who will share their knowledge of the geology, wildlife, plant life and the people of the park they love. Filled with music and nature sounds (recorded on location), our audio tour is as entertaining as it is educational. 70 minutes in length. There is no map that accompanies these audio files, but the National Park will provide one. Heading to Yellowstone as well? Then download our audio tour of Yellowstone National Park so you can get a complete understanding of both of these remarkable national parks!
