Overview

The Upper Geyser Basin is the most famous geothermal area in Yellowstone National Park and contains the greatest concentration of geysers found anywhere in the world. Spanning roughly one square mile along the Firehole River, the basin features more than 150 geothermal features, including iconic geysers such as Old Faithful, Grand Geyser, Castle Geyser, Daisy Geyser, and Riverside Geyser. The basin's remarkable density of hydrothermal activity results from a unique combination of abundant groundwater, intense underground heat, and a complex network of subterranean channels that allow superheated water to periodically erupt at the surface.

Visitors exploring the basin's extensive boardwalk system encounter an ever-changing landscape of erupting geysers, steaming fumaroles, bubbling springs, and brilliantly colored thermal pools. Many of the geysers have predictable eruption intervals, allowing visitors to witness some of Yellowstone's most dramatic geothermal displays. The basin has played a central role in Yellowstone tourism since the park's establishment in 1872 and remains one of the most celebrated geothermal regions on Earth. Its combination of geological significance, accessibility, and scenic beauty makes the Upper Geyser Basin an essential destination for anyone visiting Yellowstone National Park.
