How to Get There

From West Yellowstone (20 mi): Enter Yellowstone National Park through the West Entrance, follow Grand Loop Road southeast into the Lower Geyser Basin, and access the Fountain Group boardwalks from the Fountain Paint Pot parking area.

Overview

The Fountain Group is one of the most diverse collections of geothermal features in Yellowstone National Park's Lower Geyser Basin. Centered around the famous Fountain Geyser, the group includes numerous geysers, hot springs, fumaroles, and mud pots that showcase the extraordinary range of hydrothermal activity found throughout the park. Fountain Geyser itself is renowned for its powerful, predictable eruptions, which can send water more than 50 feet into the air from a broad pool surrounded by mineral-rich sinter deposits. Nearby features such as Morning Geyser, Clepsydra Geyser of the Lower Basin, and Fountain Paint Pot contribute to a landscape that is constantly changing under the influence of Yellowstone's volcanic heat.

Visitors exploring the boardwalks encounter bubbling mud pots, steaming vents, colorful thermal pools, and active geysers within a relatively compact area. The Fountain Group provides an excellent introduction to the geological forces operating beneath Yellowstone, illustrating how variations in heat, water chemistry, and underground plumbing produce dramatically different thermal features. Because of its accessibility, variety, and frequent geothermal activity, the Fountain Group remains one of the most rewarding destinations for visitors seeking a comprehensive Yellowstone thermal experience.
