Old Faithful, the famous geyser in Yellowstone National Park, erupts approximately every 90 minutes, although the exact timing can vary. Eruptions typically last between 1.5 to 5 minutes, reaching heights of 100 to 180 feet. Visitors can check estimated eruption times at the park's visitor centers or on the Yellowstone National Park website for the most accurate predictions.
