Castle Geyser, Yellowstone National Park

#19 of 66 in Nature in Yellowstone National Park
Hot Spring · Hidden Gem · Nature / Park
Watch the spectacle of nature at Castle Geyser, featuring the largest cone in Yellowstone. The geyser once resembled a medieval castle with turrets and crenellations, but the constant eruptions have changed its appearance over time. Today, the geyser erupts every 10-12 hours; so check the predicted time of the next eruption at the visitor center before taking a short walk down the paved path from Old Faithful. If you are early, wait for the 1-hour show of spraying water and steam at the shaded area with benches that offers views of Grand Geyser and Geyser Hill as well. Using our custom trip planner, Yellowstone National Park attractions like Castle Geyser can form part of a personalized travel itinerary.

  • We saw old Faithful go and then we were at Castle which erupted and was not as tall as old faithful but still a good blow. We were lucky with our timing.  more »
  • Castle Geyser was my favorite geyser in the park. We lucked out and the geyser started erupting the minute we walked up to it. It puts on an awesome show that seems to last forever!  more »
  • Didn’t see it erupt but it was still cool
  • I decided to read a little bit and ended up camped on a bench in front of Castle Geyser. There is a nice walking path in front of the geyser leading into the upper geyser basin. Be sure to check when this geyser will erupt because it only goes off twice everyday. Worth seeing if you can, especially to see the water cascading down the sides of the rocks
