Yellowstone National Park

Lower Geyser Basin

Lower Geyser Basin, a large area of hydrothermal activity, can be viewed by foot along the boardwalk trail at Fountain Paint Pots and by car along the three-mile Firehole Lake Drive.

Along Firehole Lake Drive you'll find Great Fountain, one of the great geyers of Yellowstone. Its splashy eruptions send jets of diamond droplets bursting 100-200 feet in the air, while waves of water cascade down the raised terraces. Patience is a virtue with this twice-a-day geyser, as the predictions allow for a two-hour window of opportunity.

Fountain Flats Drive departs the Grand Loop Road just south of the Nez Perce picnic area and follows along the Firehole River to a trailhead 1.5 miles away. From there, the Fountain Freight Road hiking/biking trail continues along the old roadbed giving hikers access to the Sentinel Meadows Trail and the Fairy Falls Trail. Also along this path is the only handicapped-accessible backcountry site in the Old Faithful district at Goose Lake.
