Montezuma Well, Rimrock
(4.7/5 based on 340+ reviews on the web)
Montezuma Well, a detached unit of Montezuma Castle National Monument, is a natural limestone sinkhole near the town of Rimrock, Arizona through which some 1,500,000USgal of water emerge each day from an underground spring. It is located about 11mi northeast of Montezuma Castle.The Well measures 386ft in diameter from rim to rim and contains a near-constant volume of spring water even in times of severe drought, amounting to approximately 15,000,000USgal. The water is highly carbonated and contains high levels of arsenic. At least five endemic species are found exclusively in Montezuma Well: a diatom, a springtail, a water scorpion, an amphipod, and a leech — the most endemic species in any spring in the southwestern United States. It is also home to the Montezuma Well springsnail.Montezuma Well's steady outflow has been used for irrigation since the 8th century. Part of a prehistoric canal is preserved near the park's picnic ground, and portions of the canal's original route are still in use today.As with Montezuma Castle, the label "Montezuma" is a misnomer: the Aztec emperor Montezuma had no connection to the site or the early indigenous peoples that occupied the area.

  • Great to see the lifeline that the well would have provided to the very early settlers of the region such as those at Montezuma's castle. You can walk down to the land edge which is a welcome cool spot.
  • Go all the way down..early in the morning. More wildlife is running about then. It can be little steep but short walk. If you meditate at all and like green quiet peaceful places..for me this area works well. Interesting Arizona historical sites. It's one of my favorite short drive go to hideaways.
  • Wonderful experience. A deep hole in the desert full of water. And the cliff dwellings inside are amazing. Also the irrigation channel down by the Verde river was so cool.......well worth seeing
  • Very interesting. Good place to stop on a road trip to stretch your legs and learn something new.
  • I went expecting a hole with stagnant water at the bottom. I was so pleased to find an amazing variety of beauty. =) Definitely worth a trip to see it. No fee, paved pathway most of the way, Indian ruins... Can't go wrong here.
