Mt. Olympus Wisconsin Dells: Water Parks, Coasters and What to Know

The Roman Colosseum replica at Mt. Olympus Water and Theme Park in Wisconsin Dells

You can't miss Mt. Olympus. The Roman Colosseum, the giant Trojan horse and the wooden coasters line the road on the way into the Dells. It's a water park and theme park resort with four parks in one: an indoor and an outdoor water park, plus an indoor and an outdoor theme park with roller coasters and go-karts.

We've driven past it on our Dells trips, which is where these photos are from, but we haven't spent a day inside yet. This guide is built from the park's own information to help you plan, and I'll add our take when we go.

Park admission comes with your stay

You can arrive as early as 9 am on check-in day to get your passes and head into the parks before your room is ready.

The water parks

Outdoor (summer): the big one is Rise of Icarus, which opened in 2024 and is billed as America's tallest waterslide at 145 feet (48" minimum). There's also a wave pool, a lazy river, a six-lane racer and Icaria, a kids' area with 10 slides.

Indoor (year-round): connected to Hotel Rome, with Medusa's Slidewheel (America's first SlideWheel, 42" minimum), slides, a lazy river and hot tubs.

The indoor theme park

Good for little kids and bad weather: mini golf, a climbing wall, bumper cars, teacups, kiddie rides and an arcade, all open year-round.

Staying at Mt. Olympus

The resort has everything from basic rooms to suites that sleep 10, plus two houses and a campground with cabins. Rooms vary a lot in age and location, and some are in buildings farther from the parks. Guest reviews commonly mention dated rooms, uneven cleanliness and crowds at peak times, along with praise for the parks and the convenience. If you book, check which building your room is in and how far it is from the parks.

The park included passes are a great value if your family will spend most of the trip on rides. If you'd rather have more space and a quieter place to come back to, a vacation home and day tickets can work just as well. Our two homes are a short drive away. See our homes.

Tips

Check heights before you go. Most of the big coasters and slides need 48 inches.
No outside food or drinks in the parks.
Lockers, strollers and wagons are available for a fee.
Lines may close up to an hour before the park does, so don't save the big rides for last.
Look for specials. The park runs room deals with park tickets included, and in 2026 it offered free early-season outdoor water park tickets.
