Fodor's Expert Review Old Faithful

Almost every park visitor makes it a point to view the world's most famous geyser, at least once. Yellowstone's most predictable big geyser—although neither its largest nor most regular—sometimes shoots as high as 180 feet, but it averages 130 feet. The eruptions take place every 50–120 minutes, the average is around 94 minutes. Check the park website, visitor center, or the lobbies of the Old Faithful hotels for predicted times. 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 1.6-mile loop hike to Observation Point yields yet another view—from above—of the geyser and the surrounding basin.
