Explore the West Thumb Geyser Basin trail guided by an engaging audio tour. This guide will provide you with fascinating stories, useful tips, and clear directions as you traverse the boardwalk beside Yellowstone Lake at your own leisure.

Venture into a lakeside world of vivid springs, eruptive geysers, and deep pools, all shaped by the volcano beneath Yellowstone. As you journey, you'll gain insight into how fluctuating temperatures, microbes, and subterranean plumbing contribute to the ever-changing colours and features of West Thumb. Each stop along the way uncovers a blend of science, history, and an ideal photo opportunity.

The trail includes several major highlights, such as Abyss Pool, one of Yellowstone’s deepest hot springs that plunges about 53 feet. This former eruptor has a dramatic past that continues to captivate scientists. Blue Funnel Spring, once a vigorous feature, now feeds Abyss Pool; its cooling waters are a testament to the basin’s constant evolution. Fishing Cone is another must-see curiosity, a famed lakeshore geyser where people once "boiled" trout, an activity now prohibited. Finally, you'll see the warm colours of Thumb Geyser, caused by the thermophilic microbes that cover this formation.
