Water World's

Picture this. You are standing inside a clear capsule at the top of a 60-foot tower in Federal Heights. A countdown runs. Then the floor drops out from under your feet and you are gone, screaming through more than 425 feet of slide before your brain catches up.

That is Aspen Falls. And it is the first drop-capsule slide the Denver metro area has ever had.

It opened Thursday, July 16, 2026, at 10:30 in the morning as part of Summit Canyon, which is the biggest thing Water World has built since 1986. We are talking roughly 2.5 acres, a

The tower changes everything

Here is the thing most people do not realize when they pull into the lot. Water World is a 70-acre park with more than 50 attractions now, but it started in August 1979 with two slides. Two. It was Colorado's first water park, run by the Hyland Hills Park and Recreation District, which is a publicly funded special taxing district that has operated the place since day one.

So this expansion is not some corporate cash grab. It is a public rec district reinvesting in a park it has run for over 45 years.

The centerpiece is a 60-foot Lookout Tower, which is now the highest point at Water World. That tower feeds four rides, and each one hits different.

Aspen Falls is the drop capsule I already mentioned. Stand up, get sealed in, watch the floor disappear.

Marmot Mayhem is one of the first HIVE waterslides in the world. In the world. It has two open-air 360-degree helixes, and you can ride it solo or drag a friend along with you.

Columbine Cascade is a body flume that runs more than 520 feet, and over half of that length is clear fiberglass, so you can actually see the sky and the tower whipping past while you slide.

Runoff Rapids is the high-speed tube ride, two switchbacks, near-zero-G sections that lift you right off the tube for a second. That is the one that gets the involuntary noises out of people.

It is not just for the adrenaline crowd

And look, not everybody wants to get shot out of a capsule. Summit Canyon knows that.

There is Critter Cove, which is about 7,500 square feet of children's pool with five nature-themed slides, plus spray features and tipping buckets for the little kids. There is Creekside Crossing, an over-water obstacle course with rope vines, floating logs and lily pads, which is exactly the kind of thing that looks easy until you are eating pool water in front of your family. Puddle Dunker gives you three in-water basketball hoops. And Emerald Lake is the relaxation pool, floats and a waterfall, for when you have had enough and just want to bob around.

So the whole zone works whether you are 8 or 38.

Goodbye Calypso Cove

Now, if you have been coming to Water World for years like a lot of Front Range families have, Summit Canyon is sitting where Calypso Cove used to be. Calypso ran since the early 1980s, and it is where the old Screamin' Mimi lived. So there is a little nostalgia getting paved over here, but honestly, trading a 40-year-old section for a world-first slide is a fair deal if you ask me.

Bob Owens, Water World's Deputy Director of Enterprise Services, said crews had been building this area since August of the prior year. So this was close to a full year of construction to pull it off.

What it costs and why the timing matters

Let me talk money, because this is where locals win.

Online tickets run $42.99 to $49.99. Buy at the gate and you are paying $57.99, so do not do that. Plan ahead. And here is the one people sleep on. If you are a Hyland Hills resident, you pay
