  • Address: Yellowstone National Park, Wyoming, USA
In 1870, when members of the Washburn Expedition happened upon this Yellowstone geyser, they noted the shape and structure of the crater resembled the tower of a castle. Today, much of that stoic castle tower has gradually dissolved and eroded, although a 90‐foot (27-meter) column of boiling water still erupts with regular frequency. On average, the Castle Geyser has an eruption cycle in the vicinity of 10‐12 hours, and eruptions will last for 20 minutes before the water changes to steam. As opposed to nearby Old Faithful, however, predicting the timing of Castle Geyser can be a little bit tougher, with the tradeoff being the Castle’s roar when the water switches to steam. For the first 15 minutes of Castle Geyser’s steam phase, visitors may experience a thunderous roar like the sound of an oncoming train, as the geyser releases its pent up energy and belches a stream of thick white steam towards the open blue sky above. 

Practical Info

The Castle Geyser is located in the Upper Geyser Basin, and is easily accessed by following the trail that leads around from Old Faithful. Sometimes, when diligently waiting for Old Faithful to go off, you can see the peak of the Castle Geyser erupting over the trees, and since the distance is so short between the two geysers you can make it over to Castle Geyser in time for the roar of the steam.
