This geyser location is not so crowded, but has all the features from other geyser locations. Furthermore, it is the starting point of one the most beautiful hikes in Yellowstone, the Mystic Falls trail. Blue is my favourite color and there are a lot of blue water pools here. You can stare at the water for hours, the clearness is unbelievable you have to see it. Only the steam clouds above the pool reveals that water is really hot!
