Create an itinerary including Castle Geyser
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.

  • I enjoy the entire geyser scene in Yellowstone; however, it was interesting to me that Castle Geyser was my son's favorite. Definitely see it for it captures one's imaginations.

  • This geyser is right near the trail and very active. It's a great place to get pictures from multiple angles!

  • 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
  • We were watching old faithful and this geyser started erupting and it was beautiful. We started walking towards it and it was going on strong for a while after we reached there. You can go much closer to it than old faithful.
