Old Faithful Geyser

Old Faithful is considered the most famous, most predictable, and most heavily researched geyser in the park. It is located in the Upper Geyser Basin near its namesake Old Faithful Lodge and visitor's complex. Every year, millions of visitors to Yellowstone crowd Old Faithful's circular boardwalk and seating area to view eruptions, which occur on average every 90 minutes. While frequent Yellowstone guests might grow to find it pedestrian, this famous geyser does not fail to impress, with bursts breaking 80 - 100 ft.
