This summer, we had the opportunity to visit and review the Mount Olympus outdoor water park and amusement center in Wisconsin Dells, and I must say, it exceeded my expectations. Mount Olympus tends to have some concerning reviews online, but most of these focus on the lodging rather than the waterpark. For my thoughts on their lodging, check out my review of a winter trip when we stayed there.
Mount Olympus boasts some highly marketable claims regarding its attractions, and while these seem designed to be easily advertised, they are also fun to experience. This includes the world’s tallest waterslide, America’s first rotating slide, the world’s fastest lazy river, one of the largest wave pools in the world, and the largest pool in Wisconsin Dells. There is a variety of other attractions to keep everyone busy. They have a huge lodging resort, and the park can get crowded quickly despite its size. Read ahead for all the details.
World’s Tallest Waterslide
The Rise of Icarus waterslide holds the title for the World’s Tallest Waterslide. It opened in 2025 and stands 145 feet tall, towering over the rest of the park. This is an enclosed body slide that loops around the tower of stairs you climb to get to the top. While the slide itself isn’t overly unique, there is something fun about saying you’ve ridden the World’s Tallest Waterslide.
In addition to the main slide, there are four additional slides leaving at the 60-foot mark. They offer various intensities, including a plunge-like slide, a more meandering body slide, and a couple in between. Minimum height is 48″ for all the slides, and the maximum weight is 300 lbs.
Medusa-America’s First Rotating Waterslide
Mount Olympus has Medusa, America’s first rotating slide wheel. This slide tends to make it to the front cover of much of the Wisconsin Dell’s marketing material, and for good reason. It’s a sweet-looking slide and is hard to imagine what it will feel like to ride. This slide is part of the indoor park and is often, but not always, available during the summer.
Medusa is similar to a family raft ride and has a minimum height of 42″. After a short drop, you enter into the rotating aspect and then slosh back and forth in a rather unpredictable way until finishing the ride with a dark and fast portion of enclosed slide. It isn’t my favorite ride, but novelty alone makes it a must-ride in the Wisconsin Dells.
Posiden’s Rage-A HUGE wave
This wave pool is advertised as “one of the planet’s largest wave pools,” which I think actually undersells the unique and fun aspects of this attraction. It is a large wave pool, but this wave pool does NOT have the standard 10 minutes of waves followed by 10 minutes of rest. Posiden’s Rage has one humongous wave every two minutes. This wave is 9 feet tall. It bowls over most guests and will literally sweep you off your feet. This is not a wave pool for young kids, fragile people, or those who prefer to stay in control. Many people won’t like it, but just as many people totally love it. I wish I had a better picture of the carnage it leaves behind because it is really quite impressive, but I was too busy making sure my kids were ok.
If Posiden’s Rage doesn’t sound like your kind of wave pool, have no fear, there is a more sedate and average wave pool called Tidal Wave as well. This wave pool features tubes for lounging and a typical wave rotation with calm water.
A Fast “Lazy” River-The River of Troy
This “Lazy” River is advertised as the world’s fastest, which seems like a hard claim to substantiate, but I would agree that it’s the fastest lazy river I’ve seen at a water park. My kids loved the extra speed, but outside of that, it is a typical lazy river with lots of tubes and a few water features. It doesn’t meander through the park but rather stays in one area. This means the scenery is a bit dull, but it is much easier to keep track of your group.
Wisconsin Dells’ Largest Swimming Pool
The Great Pool of Delphi is a huge pool with a spacious sun deck. It has 27,000 sft of swimming space. My kids love hanging out here after such a long and busy day. There is an island in the middle, allowing for lots of space to jump in and play. For more interactive play, there is a kids’ splash place on one end. Mount Olympus boasts space for 4,000 people in this massive pool!
The Lost City of Atlantis-Climb and Slide
This climb-and-splash play area is one of the best we’ve seen! It welcomes visitors of all ages but has some larger slides than are typical for this kind of structure. One of my favorites was a small body toilet bowl slide. When you are in line, you can see everyone sliding in the bowl. There is also a “boomerang” tube slide and a more typical twisting tube slide. Those three slides have a minimum height of 42″. There are three additional body slides, which are smaller and do not have a minimum height requirement.
Family Raft Slides and Mat Slides
Finally, there are three more slide types. One is a large mat slide that allows for up to six people to ride together. There are two family raft slides, Titon’s Rage and Titon’s Fury. One is a twisty-turning slide, and the other is a straight slide with drops. We love family raft slides because it’s easy for everyone to enjoy them together.
Icarus Splash ‘N Slide-Toddler and Young Kids area
The area designed for the youngest guests is the Icarus Splash ‘N Slide. One of my favorite features is that it is designed in a way that allows you to see the entire place from the front. This makes supervising independent-feeling youngsters a bit easier. There are ten slides of various heights, but you have to be 36″ and over to ride, and they only allow single riders.
Go-Karts for All
There are six go-kart tracks at Mount Olympus in Wisconsin Dells. Four of these are for drivers 55″ and over. Those under 55″ can ride with someone over 18 years old. The karts are typical of what you find at amusement centers and do not require helmets to ride. The various courses have different features, including one that drives under the large wooden Trojan horse.
There is a great starter track for the littlest drivers called Tiny Heroes. This is for drivers 5 years and older who are between 40″ -47″ tall. It is a small track where parents can see their little drivers for the whole course. For a step up, drivers between 45″-56″ can drive the Orion go-karts. This has slightly faster cars and a larger track.
The Rollercoasters
Mount Olympus has five roller coasters. Only one isn’t a wooden coaster, and that is the Little Titans, designed for kids between 40″ and 56″. The next step up is Pegasus, which is a wooden roller coaster for those over 42″. My kids were excited to try this coaster and giggled throughout, but no one was willing to ride it again. Like most wooden roller coasters, it’s pretty bumpy.
The other three roller coasters are for riders 55″ and over. The Hades 360 roller coaster is the world’s first upside-down wooden roller coaster and boasts the longest underground tunnel of any roller coaster. Cyclops and Zeus are the other two roller coasters. While I loved roller coasters, the older I get, the more I avoid the wooden ones. They tend to settle a bit over time and seem to get a bit bumpier every year. Watching people hold their heads while riding doesn’t make me any more keen to jump on.
A Couple More Rides
The Manticor is a swing ride for those 48″ and taller and stands 140 feet tall. For an extra cost, those brave enough can try Apollo. It sails you smoothly up to 120 feet in the air. This ride has an additional cost to the basic park admission; in 2025, it was $12.99 per rider.
Indoor Waterpark
The best feature of the indoor waterpark at Mount Olympus in Wisconsin Dells is Medusa, as described above. They also have a lazy river with tubes, a tube slide, and a body slide. The tube slide is called Cerebrus and has no minimum to ride with an adult, but solo riders must be 48″. The body slide called Hydra is for riders 55″ and over.
Medusa’s Shipwreck is a fun area for toddlers and young kids. It features shallow water and a few small body slides. It is designed for kids 48″ and under. My kids loved it when they were young, but due to the design, it is challenging to supervise more than one child with only one adult.
There are two hot tubs, a large pool, and a shallower play area for kids.

Indoor Carnival
Mount Olympus describes this as an indoor theme park, but I would call it more of an arcade with carnival rides geared towards young kids. Most of the rides are designed for young visitors and school-aged kids, and older kids may get bored quickly. They do have an arcade in the middle, though the variety of the games isn’t great.
There is a nine-hole putt-putt course and a rock climbing wall. Climbing requires an extra fee. One unique feature is a “life-size pool,” which is a game of pool so large it uses soccer balls and kicking instead of sticks.
Admission and Lodging
Access to both indoor and outdoor water parks, as well as the theme park and indoor carnival, is all included for Mount Olympus resort guests. Even if you are staying at the resort, you will probably still need to drive to the waterpark. Parking is free for resort guests. Only those staying in Hotel Rome will be able to walk from their room. I’ve stayed in Hotel Rome and didn’t have issues, but you should expect a budget hotel. I know many people who stayed at other parts of Mount Olympus who now prefer other lodging. If you stay at Mount Olympus, be ready for budget accommodation.
If you choose to stay elsewhere, you can still buy day tickets to the parks. Price as of summer 2025 is $33 online or $38 at the gate. This price applies to all ages. They occasionally have big sales, sometimes as low as $5 per person! Keep in mind that if you are not staying at the resort, you will need to pay a $40 parking fee at the waterpark. You walk from the parking lot through the outdoor amusement center to get to the waterpark-it’s a pretty substantial walk.
What to Bring
A good day starts with the right stuff. I’m a minimalist when it comes to packing, but here is what I like to bring into the park.
I am an Amazon affiliate and occasionally use affiliate links. When you use those links, I get a small commission. I appreciate your support!
- Towels. The Resort towels are only convenient for guests of Hotel Rome-Try these low pack volume, quick dry ones
- Water Shoes or sandals
- Sunglasses with a leash-You need a leash, or you will have to hold them on slides
- Sunscreen
- Full water bottle-There are several places to fill them up in the park
- Waterproof band-aids
- Swim suits and dry clothes
- Goggles for kids in the wave pool
- Sunshirt or cover-up
- Lifevest for the kids-Yes, they have lifevests, but they are old school and not the most comfortable. You should have a life vest if you are not a strong swimmer.
- A plastic bag for your wet clothes on the way home
No water wings or any other non-Coast Guard-approved flotation devices are allowed.

What do I do with my Phone?
Signs state that no electronic recording devices or phones are allowed on slides and rides, but that rule wasn’t enforced at any of the times we were there. The safest place for the phone is in the lockers, but then you can’t take pictures. I carried my waterproof phone in a running belt. This gave me quick access, but it isn’t waterproof, and it doesn’t help me if I drop it. Sometimes I like to combine my belt with a leash that connects to my phone, using a piece that fits under the case, like this one. One popular option is a waterproof case with a lanyard, though I don’t think those are allowed on some of the rides. This option makes the phone too bulky to fit in my belt and feels less secure on the fast rides. It also creates lower-quality photos, as the case seems to steam up slightly.
Food Options
Food prices are high, as is expected at this sort of attraction, and carry-ins are not allowed. They searched my bag at the entrance, but it was quick, and they didn’t say anything about the many hidden snacks that every mom carries in random pockets. I was pleasantly surprised by the quality of the flatbread pizzas. I also love that there are water fountains to fill up your bottles, saving you money on buying drinks. Prices for 2025 include pretzels and cheese at $5.50, a cheeseburger basket for $14, chicken strips for $13, soda pop at $4.50, and Dippin’ Dots at $7.25. A bottle of water was $4, and beer was $8-9.
In Conclusion
We had more fun at the Mount Olympus waterpark in Wisconsin Dells than I expected. I believe the low expectations were related to the worrisome online reviews. The poor reviews are mostly associated with the Mount Olympus budget lodging, not their waterpark. The water resort is spread out, but that layout gives each feature plenty of space. There is a lot of variety. If you watch for deals, you can get tickets for a really low price! I have found the best deals during the Christmas shopping season. For $5 a ticket, even if you have to pay for parking, you can’t go wrong!
