Introduction

Dragons Mouth Spring in Yellowstone's Lower Geyser Basin is one of the park's most dramatic geothermal features. This acidic hot spring constantly belches roiling hot water and dense steam from a cave-like rock opening with a low roar, like a hidden dragon breathing in anger. Rich in sulfides, the water is a murky gray-green, and the vapor carries a strong sulfur smell that adds to the primordial mystique. Near boiling temperature, the plume condenses into a towering steam column in cold weather, visible hundreds of meters away. The boardwalk lets you feel its full sonic and visual force up close, one of the most sensorily striking stops in Yellowstone's geothermal tour.
