Roughly an hour and a half away from Bozeman is Yellowstone National Park!!!
"This is a very easy to get to waterfall on an accessible paved trail. Palisade Falls Trail is 1.2 miles out and back. There is a paved viewing area near the base of the falls which drops 80 feet from the vertical basalt cliffs. The more mobile can scramble along the rocks to the base of the falls on the mountainside. Beautiful waterfall."
"If you are into dinosaurs you must go to this museum. They had many fully reconstructed skeletons and a large number of bones and egg nests. Also includes some good exhibit on history of the area."
