Officially, the first day of summer isn’t until June 20. Unofficially, the season kicks off with your first dip in the pool or cannonball — however, you prefer to make an entrance.

While there are plenty of pools around the state, some offer superlative swims thanks to their views, waterpark amenities, and, yes, even a rock climbing wall that juts above the water.

Ahead, discover 10 unique pools for a memorable swim this summer.

Scott Carpenter Pool in Boulder

Scott Carpenter (or “Scotty” as its fans call it) is an all-out fun zone with a lazy river, slides, a high dive, and a lap pool.

But leave it to Boulder’s park and recs team also to install a rock climbing wall that towers above the pool. Built by Colorado’s Eldorado Climbing Walls, it commands a steady line of kids (and kids at heart) waiting to take turns climbing up the wall and plunging into the pool.

Historic Eldorado Springs Pool in Eldorado Springs

The historic Eldorado Springs Pool opened on the Fourth of July in 1905 and eventually became known as the “Coney Island of Colorado.”

Its ballroom hosted big acts like Glenn Miller and Hot Rize, and Dwight and Mamie Eisenhower honeymooned in a nearby cabin.

After going through a historic designation process and shutting down for improvements in 2019, the spring-fed pool reopens this summer in its prime location at the base of the Rocky Mountains and adjacent to Eldorado Canyon State Park.

“The pool holds a special place in the hearts of many, and we’re committed to ensuring it remains a cherished destination for generations to come,” says Erica Larson, director of HR and Resort Operations.

Water World in Federal Heights

Colorado may be landlocked, but don’t let that stop you from boogie-boarding or surfing. At 70 acres, Water World is one of the largest water parks in the country.

In addition to the dozens of tube rides and slides, the park has two wave pools. Cowabunga Bay, near the park’s entrance, is for body surfers who can launch from a platform into a steady set of gentle waves. Thunder Bay is the main wave pool, which has a giant Pepsi logo and churns out a steady stream of ocean-like waves for a few minutes several times each hour.

Other ways to beat the heat include laps in the lazy river (steer your inner-tube underneath a waterfall) or by catching some waves on the surf simulators.

Water World celebrates its 45th anniversary this summer.

The Springs Resort in Pagosa Springs

Every nature-loving Coloradoan has a favorite hot spring destination, and the state has so many of these geothermal tubs bubbling up that a historic loop connects some of the famous ones.

In the southern part of the state, The Springs Resort’s two dozen pools sit on the banks of the San Juan River. What sets these pools apart is that visitors can enjoy unique experiences in them, like a floating aqua massage and morning yoga sessions in the warm, mineral-rich waters.

Overnight guests get 24/7 access to the pools, which means soaking under the stars.
