About Mud Volcano

Mud Volcano is a captivating hot spring in Yellowstone National Park, showcasing bubbling mudpots and striking acidic features. Its raw geothermal energy creates a dramatic landscape, highlighted by the thunderous, steam-filled Dragon’s Mouth Spring. This hot spring offers a fascinating glimpse into nature’s underground forces.

Getting There

Reach Mud Volcano via a short 10-minute walk from a nearby parking area, which has limited spots and can fill quickly during peak times. The easy boardwalk trail makes the site accessible without strenuous hiking, allowing you to explore safely while feeling immersed in Yellowstone’s geothermal wonders.

What to Expect

Expect to encounter boiling mud and churning acidic pools with temperatures around 131°F. The boardwalk loop provides close-up views of the steamy, otherworldly scenery, but the scent of sulfur lingers in the air. Facilities are minimal, so the atmosphere remains natural and undisturbed, making it a compelling stop among Wyoming hot springs.

Tips for Visitors

Visit during early hours or off-peak seasons to avoid crowds and secure parking. Wear sturdy shoes and layer clothing, as geothermal areas can be surprisingly cool despite the hot springs. Stay on the boardwalk to protect delicate ground and ensure safety; clothing is required, and no swimming is allowed in these acidic pools.
