Creation While hiking on Iron Mountain in the late 1800s, Charles W. Darrow followed a whistling sound created by natural air currents and discovered the entrance to a cave system. In 1895, Darrow opened the caves to the public. Originally only accessible by foot or horseback, Darrow installed electric lights in the cave with the help of the city's
hydro-electric plant in 1887 (becoming one of the first caves to do so). In 1917, coinciding with the onset of
World War I, the caves were closed to the public.
New ownership By 1998, Steve and Jeanne Beckley obtained the land on which the cave is located. That year saw the beginning of the Fairy Caves Project, a volunteer organization coordinating caver access as well as science and conservation projects utilizing the land. This project allowed for the reopening of the cave to the public in 1999 after one year of restoration work. The caverns were accessible by bus via a station next to the Hotel Colorado. In 2002, the park was expanded, adding a pulse
gondola, a visitor center with a restaurant, an
aerial tramway, a
sluice box, and a gift shop.
Development into Adventure Park As wait time for cave tours increased, attractions were added to the park to provide patrons with entertainment while waiting. From 2005 to 2010, various attractions were added, such as a
4-D theater, an
alpine coaster, a zip ride, a swing-style attraction, and a climbing wall.
Further expansions In 2012, the park undertook its largest expansion since 2005 with the addition of three rides. These included a
Zierer children’s roller coaster and an
SBF-Visa Ferris wheel, both relocated from Wild Zone Adventures in Canada. The flagship addition was the
Cliffhanger roller coaster, relocated from the former
Celebration City amusement park in
Branson, Missouri. The coaster opened in June 2012. As of 2026,
Cliffhanger is the highest elevation roller coaster in the United States, operating at an elevation of 7,160 feet (2,180 m) above sea level.
Cave and tramway improvements (2013) In 2013, the park expanded the upper portion of its cave system. As part of this project, the original cave tour was divided into two separate tours, both being approximately 40 minutes. That same year, the
aerial tramway was expanded by adding two additional pulse sequences, bringing the total to six pulses and eighteen cabins.
Additional rides (2014–2015) In 2014, the park installed the Glenwood Canyon Flyer as an alternative to the Giant Canyon Swing. The ride was later featured on the television program
Thrill Factor in 2015, in the episode "Kari Has No Sense".
Haunted Mine Drop / Crystal Tower (2017) In early 2017, the park announced the addition of the Haunted Mine Drop, a
drop tower that descends underground and features themed elements as well as a 110-foot (34 m) vertical drop. The ride opened in the summer of 2017. The Haunted Mine Drop was renamed as Crystal Tower in 2023. ==Rides and attractions==
