Half the world's geysers are found within
Yellowstone National Park, and most of those are concentrated in a near continuous band of activity along the aptly-named
Firehole River, south of Madison Junction, culminating in the largest group of all in
Upper Geyser Basin, home of Old Faithful and many other equally large and spectacular erupters. The ten mile expanse contains examples of every other kind of geothermal feature, large and small, in backcountry settings reached by
trails, or right next to the road, and several days would be needed to see everything.
Old Faithful is also the site of a sizeable village offering every conceivable visitor facility, acres of parking space and several lodges and hotels. Paths to the nearby geysers are always busy, as are other popular sites like
Black Sand Basin,
Grand Prismatic Spring (in
Midway Geyser Basin) and
Fountain Paint Pots (in
Lower Geyser Basin), but it is still easy to find more tranquil places away from the crowds such as
Lone Star Geyser or the
River Group in the Lower Basin.

Regions of Southwest Yellowstone
Cascade CornerMeadows, woodland and waterfalls in the far southwest, centered on the Bechler and Falls rivers; several lengthy trails. Relatively low in elevation, with few thermal features
Lower Geyser BasinThe Fountain area, Sentinel Meadows, Firehole Lake and nearby geysers, the River and Quagmire Groups, Morning Mist Springs and Culex Basin. Good for wildlife viewing, especially on Fountain Flats
Midway Geyser BasinGrand Prismatic Spring, Excelsior Geyser and several other large pools. One popular trail leads to Fairy Falls and Imperial Geyser
Upper Geyser BasinOld Faithful and countless other pools and geysers, the Biscuit and Black Sand Geyser Basins. Also site of a sizeable village offering all necessary visitor facilities
Scenic Drive - North
The road through the geyser region - which is divided into the Lower, Midway and Upper Basins - starts at
Madison, 12 miles east of the main entrance to Yellowstone National Park at
West Yellowstone. The first few miles encounter no thermal areas, as the road follows the valley of the Firehole River southwards passing two notable waterfalls;
Cascades of the Firehole and
Firehole Falls, this latter reached by a one-way spur road that runs along the rim of a very steep part of the canyon. Along the main highway, the valley sides soon recede and the land opens out to reveal a large area of meadows either side of the river. This is the
Lower Geyser Basin, containing up to ten separate groups of geysers and pools of which half are easily accessed from the road. A few miles south, at the far side of the same open area, is the
Midway Geyser Basin, with fewer but larger features like Grand Prismatic Spring and Excelsior Geyser.
Scenic Drive - South
The highway then runs through another short valley and into the
Upper Geyser Basin, which has over 250 identified geysers, on both sides of the road, in an area just 1 by 2 miles. South of here, the Firehole River turns away from the highway at the 150 foot
Kepler Cascades, starting point for hikes to two of Yellowstone's backcountry geyser basins -
Lone Star and
Shoshone. This latter is a varied collection of hot pools and about 40 active geysers, arranged around Shoshone Creek at the west edge of Shoshone Lake, 8.5 miles from the road. The basin can be visited on a long day hike though most people stay overnight at one of two primitive lakeside campsites. Back on the main road, the 12 miles to
West Thumb junction encounters wooded, mountainous land, twice crossing the continental divide, and passing several more trailheads including one for the 3 mile hike to the east end of Shoshone Lake along
De Lacy Creek.
