The Midway Geyser Basin is one of the unexpected delights of Yellowstone if you have not visited before. It is well marked and just off the road heading north after  leaving the often crowded and bustling Old Faithful complex. One of the first things that you notice are the steaming streams of hot water flowing down the sides of the hill and into the Yellowstone river. You can park in the parking lot and walk up the wide and well-maintained boardwalks that will take you through and around the various attractions to be seen in this area.  Old Faithful is iconic and a must see, but the Grand Prismatic Spring is extremely beautiful and so unexpected that it will likely be one of the highlights of a visit to Yellowstone.

 The hottest part of the spring is deep, jewel-like blue and as the water radiates away and cools, algae mats and bacteria form bands of vibrant color in bright reds, oranges, yellows and browns. The access is very easy for family members of all ages. Just make sure to keep the little ones on a short tether, as you would not want anyone falling into any of the hot/boiling water.
