Located north of Idaho Falls, the lake is shadowed by majestic Centennial Mountains that make up the Continental Divide. Picnicking, camping, fishing, hiking and boating are available. The first ever national park encompasses more than 2.2 million acres. More than 10,000 geothermal features, including world famous Old Faithful, are located within the 3,472squaremile boundary of this unique and spectacular national park. Over 60 species of mammals and 200 species of birds and a halfdozen game fish are found in Yellowstone.
Regular tours are available through the buildings of the old Railroad Ranch.
The Henrys Fork of the Snake River also meanders through the state park. At an age of less than 10 million years old, this range is the youngest in the Rocky Mountains. Wildlife viewing is one of the highlights of this park with numerous opportunities to hike, canoe or horseback ride. The area offers 35 miles of dunes to run, drive and bike over. Many of the dunes are higher than those in Death Valley.
