Grand Teton National Park and Yellowstone National park are next-door neighbors in northwest Wyoming. If you’re going to visit one you should definitely take the time to experience the other. The natural wonders never cease in these places. The mountains are epic, the wildlife is abundant, and you can see some of the largest geysers and geothermal pools in the world. If the crowds in Yellowstone are a bit overwhelming, Grand Teton definitely provided a more peaceful experience.
