Firehole River

The Firehole River, a scenic 21-mile (34-kilometer) stretch in Yellowstone National Park, winds its way northward before merging with the Madison River. This river serves as a drainage basin for many of the park’s geothermal features, collecting the warm, mineral-rich waters that give it its unique character. Visitors can enjoy the river’s inviting waters, making it a popular spot for a refreshing summertime dip. The combination of natural beauty and thermal activity creates a distinctive and memorable experience.
