While you are watching Old Faithful, make sure to explore the Old Faithful Inn and the Upper Geyser Basin right behind Old Faithful. In the Upper Geyser Basin, there are other predicted geysers, mud pools, and colorful geothermal springs. The walkway is paved or boardwalk throughout. Beware of the bison. The bison tend to roam around this basin and you may turn a corner and run into one. Try to stay at least 25 feet away from them at all times, even if it means going back the way you came from.
The Old Faithful Inn was built in 1904 and has all wooden interior and exterior. It is still open for guests to stay, but be warned it is expensive and you have to book way in advance. Even if you aren’t staying there, wander around the lobby.
Plan to spend about 2-3 hours here, more if you want to explore all over the Upper Geyser Basin.
