Mud Volcano is a great thermal area in Yellowstone that as a kid was my very favorite place to stop. It is located between Canyon, and Fishing Bridge. It is a loop hike just under a mile or a shorter 0.3 mile loop to see just Dragons Mouth, and Mud Volcano. I recommend the longer loop for the great scenery. There is a very large parking area and it can get busy.
Start in a counter clockwise direction and you will first come to the Dragons Mouth. The steam coming out of the small cavern makes a sound that sounds like a dragon is breathing. As a kid I loved this place and really believed there was a dragon in there.
Next up is the Mud Volcano. Here is the info provided at the volcano. If you look closely you can see the inside of the old crater before it blew apart.
Next up the trail climbs a hill through a pretty meadow. I have twice seen grizzly bears right by the trail here so be on the lookout and respect their space.
Next up you will see Sour Lake.
After that you will see the Churning Cauldron. This is really cool in person. You can’t tell with a picture the power of this spring.
The exit stream is kind of pretty and gross.
Looking down the trail you get good views of Mud Geyser.
Look at the hillside to see the Cooking Hillside.
As you return to the parking lot you will see the large springs right by Mud Volcano.
This is one of the more unique thermal areas in the park and is still one of my personal favorites.
