The greater region of Yellowstone National Park is known for big skies and clean (although sulfured) air. Untainted by light pollution, the park provides the perfect opportunity to view all the brilliant stars and constellations. Bring a star chart and don't forget your telescope. Also, remember it's grizzly country, so take the same precautions you would during the day.
