Grand Teton National Park is a spectacular sensation, often resting in the shadows of its more popular neighbor, Yellowstone National Park. Jagged towering peaks offer endless hiking trails and hidden lakes for exploring. Take the Jenny Lake Boat across the lake to access popular trails or venture out on a horseback ride to avoid the crowds. The Snake River offers fantastic fishing and fun rafting, either scenic or whitewater. In the winter, much of the park becomes inaccessible but you can still crosscountry ski or snowshoe at its base, take a sleigh ride through the elk refuge, or downhill ski at the renowned Jackson Hole Ski Resort.
