25 Years of Glenwood Caverns Adventure Park

America’s only mountaintop theme park in Glenwood Springs is turning 25 in 2024. To commemorate the milestone, the park plans to celebrate all season long, culminating with a “Party like it’s 1999,” salute featuring a Prince tribute band.

Two and a half decades ago, Steve and Jeanne Beckley embarked on a monumental journey, culminating in the realization of a dream nurtured over years of single-minded determination and hard work. It was in 1999 that the couple opened the Glenwood Caverns to the public, marking the end of a near-century closure. Little did they know then that their endeavor to bring the beauty of the caves to a larger audience would evolve into an iconic Colorado visitor destination, drawing thousands annually to explore the caves and experience thrill rides at what has become known as Glenwood Caverns Adventure Park, America’s only mountaintop theme park.

Turning 25 and Partying Like It’s 1999

As Glenwood Caverns Adventure Park commemorates its 25th anniversary, festivities abound with a themed celebration, “Pary Like It’s 1999” planned for Saturday, May 18. The evening will kick off with BJ the DJ from 5 to 7 p.m. The highlight of the evening will be a performance by Paizley Park, a dynamic Prince tribute band that will take the stage from 7 to 9 p.m.

Phillip Lamar formed the band at the urging of his friends and fans who convinced him that his vocal and physical attributes were spot-on resemblances of “the Purple One.” Paizley Park is named for Prince’s home and studio in Minnesota. The band came together in January 2016, just four months before Prince’s death. Paizley Park is no stranger to Glenwood Caverns having played previous crowd-pleasing shows at the mountaintop venue. For the festivities this year, guests are encouraged to channel the spirit of the occasion by donning Prince’s signature color—every shade of purple!

Party-Day Perks

In addition to the gondola discount, party-goers will receive swag bags filled with goodies and there will also be raffle drawings for amazing prizes throughout the evening during band breaks.

How it Began

Steve and Jeanne BeckleyWhile the park is celebrating turning 25, the dream began long before opening day in 1999. In the early 1980s, Steve Beckley, a petroleum engineer and graduate of the Colorado School of Mines, stumbled upon a mention of the Fairy Caves in an out-of-print book about Colorado caves. His curiosity piqued, he wrote to Pete Prebble, the then-owner, expressing his fervent desire to explore the hidden wonders within. It took 11 years of persistence and cajoling before Steve and his then-girlfriend Jeanne were granted access to the closed-off cave.

For the next six years, the Beckleys tirelessly negotiated with Prebble, eventually securing a lease for the property. They bid farewell to their jobs in Denver and embraced a new chapter in Glenwood Springs with their newborn son. A year of meticulous preparation followed, leading to the long-awaited opening of the caves to the public during Memorial Weekend in 1999—a momentous occasion marking the realization of their 18-year-old dream.
