Frommer's Favorite Experiences

Yellowstone National Park: It's the crown jewel of American parks, and it remains the prime attraction in the Rocky Mountains. This unique park offers visitors an extraordinary combination of wilderness, wildlife, and geothermal wonders.

Grand Teton National Park: The Grand Tetons are an excellent short course in Rocky Mountain parks for travelers with less time: magnificent peaks rising from the Snake River plain, alpine lakes, wildflowers, and wildlife, in a relatively small park that can be seen in a few days.
