Fodor's Expert Review Old Faithful
Almost every visitor's itinerary includes the world's most famous geyser. Yellowstone's most predictable big geyser—although not its largest or most regular—sometimes shoots as high as 180 feet, but it averages 130 feet. The eruptions take place every 60–110 minutes, the average around 94 minutes. To find out when Old Faithful is likely to erupt, check at the visitor center or at any of the lodging properties in the area, or call the geyser prediction line at 307/344–2751. You can view the eruption from a bench just yards away, from the dining room at the lodge cafeteria, or the second-floor deck of the Old Faithful Inn. The 1-mile hike to Observation Point yields yet another view—from above—of the geyser and its surrounding basin.
