The Teton mountain range is spectacular, as is the wildlife in the park. The snake river runs through part of the park, and provides habitat for a host of animals like moose and river otters! I saw four otters one morning, and four moose while in the park. There was also a female grizzly bear around the Jackson Lake lodge with two cubs, but I never saw her. It rained and hailed while I was in the park, but cleared up usually by mid-day.
