Six Flags Hurricane Harbor Chicago is a 20-acre water park in Gurnee, Illinois, sitting right next to Six Flags Great America, with 25 water slides, two pools, and an 86-foot water coaster as its centerpiece.
Whether you’re checking hours before a trip, comparing ticket and parking costs, or trying to figure out which slides your kids can actually ride, this guide covers the practical details along with the park’s history and lineup.
Quick Answer
Hurricane Harbor Chicago typically operates on select days from late May through Labor Day weekend, with its own separate admission gate and ticketing since 2021. General admission starts at $30 online, parking runs $39 (general) to $59 (preferred), and the park’s 25 slides span a 20-acre footprint anchored by Tsunami Surge, an 86-foot water coaster, and the Hurricane Bay wave pool.
Hours and Operating Season
Hurricane Harbor Chicago runs on a seasonal, select-day schedule rather than being open every day all summer — expect operation from around Memorial Day weekend through Labor Day weekend, with the fullest daily schedule during peak summer weeks and a more limited weekend-only calendar in late May, early June, and late August.
Because the schedule shifts year to year and by day of the week, check the official park-hours calendar on sixflags.com/greatamerica shortly before your visit rather than assuming the park is open — Six Flags occasionally closes the water park for weather, even when the calendar shows it as scheduled.
Tickets, Parking, and Season Passes
Single-day general admission to Hurricane Harbor Chicago starts at $30 when purchased online in advance, with pricing that fluctuates by date (weekends and peak-summer days cost more than shoulder-season weekdays, and gate pricing runs higher than online). Six Flags no longer offers a discounted same-day upgrade from a Great America ticket, so if you want to visit the water park you need a Hurricane Harbor ticket or a season pass that includes it.
Parking is separate from admission: general parking runs about $39 per vehicle and preferred parking (closer to the entrance) runs about $59. A Six Flags Great America season pass includes access to Hurricane Harbor Chicago as well as Hurricane Harbor Rockford, and add-ons like dining plans, drink packages, and parking passes can be purchased alongside it to cut per-visit costs if you plan multiple trips.
Rides and Slides: The Full Lineup
The park’s 25 water slides split roughly by height requirement. Slides open to guests as short as 36″ (with an adult) include the Skull Island kids’ area attractions. Slides requiring 42″ include Bahama Mama, Bubba Tubba, Hurricane Mountain, the Surf Rider wave simulator, Vortex, Typhoon, and Wahoo Racer. The steeper, 48″-and-up group includes Hammerhead, Barracuda, Paradise Plunge, Riptide, Tornado, Wipeout, and the signature Tsunami Surge water coaster.
Beyond the slides, Hurricane Bay is the park’s main wave pool, Castaway Creek is the lazy river, and Buccaneer Bay and Monsoon Lagoon give younger kids shallow, low-intensity splash areas with spray towers and a rope bridge. Posted height requirements are always the final word at each ride entrance, since Six Flags periodically adjusts them.
Cabanas and VIP Add-Ons
Hurricane Harbor Chicago offers reservable cabanas for guests who want a home base with shade and dedicated seating for the day. Pricing tiers vary by size and location — a King Cabana, which seats up to eight guests, has run around $250 for the day — and reservations open closer to the season and sell out fastest on weekends and holidays. Book directly through the park’s cabana reservation page rather than a third-party reseller to avoid markup.
What to Bring and Park Rules
Outside food, drinks, coolers, and grills are not allowed inside the water park, with a narrow exception for documented food allergies (limited to sealed snack bags and a small soft-sided cooler) and infant food in factory-sealed containers. Towels are free with paid admission, but locker rentals — useful for phones, wallets, and car keys — typically run $9 to $15 for the day depending on size.
Life jackets are provided at no charge at designated stations for guests who want them, and all guests riding water slides must follow posted swimwear guidelines (no exposed metal, rivets, or buckles that could damage the slides). Loose articles like sunglasses, jewelry, and flip-flops aren’t allowed on slides and rides and need to be left with a non-riding member of your group or stored in a locker.
History and Access
Before the water park existed, Six Flags floated a far larger “Entertainment Village” concept in 1997 that would have added a hotel, convention center, and shopping alongside a water park across Interstate 94. Gurnee residents organized against the plan and rejected it in an April 1999 referendum, and the company later scaled back to the water park that opened on May 28, 2005, following a $42 million construction project.
For its first 16 seasons, admission to Hurricane Harbor Chicago was typically bundled with a Six Flags Great America visit. That changed on March 22, 2021, when the water park began operating with its own separate entrance and ticketing. The lineup grew in stages over the years, from the Tornado funnel slide in 2006 to the four-acre Riptide Bay expansion in 2011 to Tsunami Surge, an 86-foot WhiteWater West water coaster that opened May 29, 2021 and was marketed at the time as the tallest water coaster in the world, going on to win a 2021 Leading Edge Award from the World Waterpark Association.
Tips for a Better Visit
Arrive at or near opening — the parking lot and locker lines both build quickly once the sun is out, and popular slides like Tsunami Surge and Tornado develop long waits by early afternoon. Weekdays outside of July generally mean shorter lines than weekends, and checking the park-hours calendar for early-closing days helps you avoid getting cut off mid-visit.
If you’re traveling with kids under 42″, plan to spend meaningful time in Buccaneer Bay and Monsoon Lagoon rather than counting on the taller slides, and bring water shoes since much of the pavement gets hot by midday in peak summer.
