Water World in Federal Heights, Colorado, opens Summit Canyon on July 16, 2026, a 2.5-acre expansion built on a $25 million public bond investment and billed as the park’s largest addition since 1986. The new zone is anchored by Aspen Falls, which the park says is the first drop-capsule waterslide in the Denver metro area.
Aspen Falls sends riders through an enclosed vertical capsule that opens on a countdown, dropping them into more than 400 feet of enclosed slide from atop a new 60-foot Lookout Tower, now the tallest structure in the park. Summit Canyon also adds three more waterslides launching from the tower, a children’s zone called Critter Cove, an obstacle course, and a leisure pool, alongside roughly 700 additional guest seats.

The Story
Water World, operated by the Hyland Hills Park and Recreation District, has spent the 2026 season building Summit Canyon, its first major new area since the Alpine Springs addition in 2021. The centerpiece, Aspen Falls, uses drop-capsule technology new to the Denver area: riders enter an enclosed capsule with a clear front panel, a countdown plays, and the floor drops away to launch them down over 400 feet of enclosed slide.
Beyond Aspen Falls, the zone includes three additional slides launching from the 60-foot Lookout Tower, the children’s-focused Critter Cove, the Creekside Crossing obstacle course, and the Emerald Lake leisure pool. The $25 million project was funded through a public bond, reflecting the scale of the investment for a park that first opened in 1979 as one of Colorado’s original waterslide destinations.
What It Means for Visitors
Guests visiting Water World this summer will find the park’s tallest-ever structure and a new thrill option that park officials say fills a gap in the local waterslide market. Deputy Director Bob Owens said Summit Canyon is designed to offer “something for everyone,” pairing high-thrill drop slides with family and children’s spaces so groups with different comfort levels can stay together. Because the opening lands in mid-July, peak summer crowds should get the fullest first look at the new zone before the park’s season winds down around Labor Day.
