Welcome to the Upper Geyser Basin, home of the famous Old Faithful! Not only that, but the majority of the world's active geysers are located here, too.
If you plan on watching Old Faithful erupt, make sure you get here early. The limited benches will fill up fast. There is an Observation Point to view Old Faithful. It's a bit of a hike, but there are fewer people. The Observation Point is roughly 0.8 miles from the Visitor Center. If you want to walk the entire loop, then it is roughly 2.1 miles.
I recommend circling the entire Upper Geyser Basin. The entire loop, including the Observation Point, is roughly 4.0 miles (6.4 km). Feel free to go your own path, but I suggest walking up the mountain to the Observation Point, coming down via the Solotary Geyser trail. Then, circle the Geyser Hill before continuing down to the Morning Glory Pool. You then walk the road back to Old Faithful, passing by Daisy Geyser and Castle Geyser. Speaking of which, there are 4 other geyser eruptions you can view other than Old Faithful: Castle, Grand, Daisy, and Riverside! Eruption time and day(s) are posted in the visitor center and online. So, be sure to do your research before heading out for the day!
