Mud Volcano Area, includes Dragon’s Mouth Spring – interesting to see, but not one I have to see again. If you are short on time, skip this area.
Old Faithful – isn’t quite as faithful as it used to be. The time of eruption is about every hour-and-a-half. It was a lot of waiting as we arrived right after an eruption. We were eventually rewarded and it was interesting to watch. Did you know that Yellowstone National Park is considered on of the largest active volcanoes in the world? It’s not the typical volcano in scale or appearance.
Midway Geyser Basin with the Excelsior Geyser (third largest geyser in the world), Turquoise and Opal Pool, and my favorite…the Grand Prismatic Spring, the largest hot spring in Yellowstone and second largest in the world. This is one area I would return to every time we visit Yellowstone on vacation.
Mammoth Hot Springs that include unique limestone terraces. This is quite an interesting spot to visit and explore. I would definitely go back to this area again.
