We continued South, heading for Yellowstone NP. We entered Yellowstone NP in the North, making our way to the Albright Visitor Center in Wyoming. After lunch we crossed the state border back into Montana for a walk to a swim in the boiling river. Here hot spring water mixes up with the cool river water making a nice spot for a relaxing bath.
From the boiling river we made it back to the visitor center for a walk around the terraces of Mammoth Hot Springs.
