Few natural landmarks are as world-famous as Old Faithful Geyser in Yellowstone National Park. Located in the Upper Geyser Basin, this legendary hot spring has captivated visitors since the park was established in 1872. True to its name, Old Faithful erupts on a remarkably predictable schedule, shooting water and steam into the sky with a consistency that has made it one of the most photographed features of the American West.

What Makes Old Faithful Special?

Old Faithful is not the tallest geyser in Yellowstone—that title belongs to Steamboat Geyser—but it is certainly the most reliable. On average, it erupts every 90 minutes, with intervals ranging from 60 to 110 minutes. Each eruption lasts between 1.5 to 5 minutes, and the water column can soar 106 to 185 feet high.

The predictability of Old Faithful comes from the underground plumbing system: a network of chambers and constrictions that fill with superheated water and then release the pressure in a dramatic burst. Park rangers and geologists can forecast the next eruption with remarkable accuracy, making it one of the few natural events on Earth you can schedule into your day.

Best Times to Visit

• Morning & Evening: Crowds are smaller, light is better for photography, and wildlife is more active.
• Summer: Offers the most comfortable weather, but also the largest crowds. Arrive early for good viewing.
• Winter: With snow all around and fewer visitors, watching Old Faithful erupt in the crisp, cold air is a magical experience.

Viewing Old Faithful

• Boardwalks & Benches: Surround the geyser, providing safe and clear viewing spots.
• Old Faithful Visitor Education Center: Features interactive exhibits on hydrothermal activity and offers updated eruption predictions.
• Old Faithful Inn: Built in 1904, this historic lodge has prime views of eruptions from its massive log lobby and outdoor deck.
