Quick Answer: Is This the Oasis Water Park You Mean?
Yes, this page covers Oasis Waterpark & Fun Center in Niles, Illinois, operated by Niles Park District at 7877 Milwaukee Avenue, Niles, IL 60714.
This is not the Arizona Grand Resort’s Oasis Water Park in Phoenix. The Niles venue is a seasonal outdoor municipal-style waterpark built around swimming, children’s water play, slides and diving rather than a large destination resort.
Best fit: local families wanting a summer pool-and-slides day, smaller children who can use the zero-depth/spray areas, and repeat Niles-area visitors who may benefit from a season pass.
What Is Actually at Oasis Waterpark?
💧 Zero-Depth Pool
A gradual-entry pool makes the facility different from a standard lap-pool visit and gives families a lower-depth entry area.
🛝 Three Slides
The district lists three slides. Two of them require riders to be at least 48 inches tall, so measure children before promising slide access.
🧒 Children’s Splash Pad
The spray-pad features are for guests under 48 inches. Adults are not permitted on the spray-pad features.
🏊 Diving Boards
Diving-well users must be able to swim independently from the board to the side and may be asked to complete a swim test.
🍦 Concessions
A concession stand is available. Outside food, drinks, glass containers and coolers are restricted inside the facility.
👨👩👧 Local Family Scale
Expect a community aquatic facility rather than a huge all-day resort complex with dozens of thrill slides or a hotel attached.
Oasis Waterpark 2026 Admission Prices
Prices below are the published Niles Park District rates checked for the 2026 season. Resident pricing requires qualifying proof, so do not plan around the lower rate unless you can meet the district’s residency requirements.
2026 Pool Passes: Is a Season Pass Worth It?
Individual
Resident / non-resident
A resident paying $10 daily reaches roughly the same spend after about 12 full-price visits.
Family of 4
Resident / non-resident
Four resident daily tickets total $40. The $278 pass reaches a simple admission-only break-even around the seventh visit.
Early Pool Access
On published pass-holder swim periods
Pass holders receive an earlier swim period on qualifying days, but holiday exceptions apply.
Full Published 2026 Pass Fees
The district defines family members for these passes as parents and their non-adult children aged 21 and under residing in the same household. Pool passes are non-refundable.
New pass: the district directs visitors to purchase in person at Howard Leisure Center. Renewal: use the district’s current renewal instructions or call Howard Leisure Center at 847-967-6633.
Verify current pool-pass instructions on the official Oasis pageOasis Waterpark Opening Hours 2026
Oasis does not use one opening schedule for the entire summer. The season changes from pre-season weekends to daily full-season operation and then to a reduced late-summer schedule.
📅 Visiting in early September?
For the published August 22–September 7 period, Oasis is closed Monday-Friday, with open swim on Saturday and Sunday from noon to 6:00 PM. Labor Day, Monday September 7, is listed for open swim from 11:00 AM to 6:00 PM.
Do not rely on generic map hours. Staffing and weather can change operations. Call 847-967-6648 if your trip depends on the pool being open.
Will Your Child Actually Be Able to Use the Attractions?
48 inches or taller
Two Oasis slides require a minimum height of 48 inches. Meeting the height rule does not override posted instructions or staff decisions at an individual attraction.
Under 48 inches
The spray-pad features are specifically for guests under 48 inches. Adults are not allowed on those spray-pad features.
Under age 12
Children under 12 must be accompanied by an adult aged 18 or older.
Age 5 and under
The current district rules tell parents to keep children aged five and under within arm’s reach.
Family Decision Board
👶 Toddler Visit
Good starting point: zero-depth and age-appropriate water-play areas.
Check: swim-diaper rules, close adult supervision and whether the spray features suit the child’s height.
🧒 Child Under 48″
Main limitation: two slides require 48 inches.
Alternative: pool and eligible splash features can still make the visit useful.
🛝 Child 48″+
More options: height may open access to two slides.
Still check: posted attraction instructions and swimming ability for diving features.
🏊 Confident Swimmer
The diving well may be attractive, but independent swimming from board to pool side is required and a swim test may be used.
🌙 Short Visit
Compare the twilight rate with normal admission when your date has usable 6:00–8:00 PM operation.
🔁 Frequent Local Family
Run the pass break-even calculation before paying for several daily visits because previous daily admissions are not credited toward a pass.
Weather Can Change the Whole Visit
🌡️ Below 68°F
The published closing policy allows the pool to close when the temperature is below 68°F.
⛈️ Storms
Storms that threaten safety can trigger closure. A sunny morning does not guarantee the full operating day.
👥 Very Low Attendance
The pool may close when there are 25 or fewer guests within an hour timeframe.
🎟️ No Weather Rain Check
The district states that refunds or rain checks are not issued when Oasis closes due to inclement weather.
Rules That Can Affect Your Visit
🔐 Lockers
Coin-operated lockers are listed at $0.25. The district encourages their use but does not accept responsibility for lost or damaged belongings.
🩱 Swimwear
Swimmers must wear lined swimsuits. The district restricts street clothes, cutoffs, mesh shorts, underwear, shoes and other unsuitable clothing in the water.
👶 Swim Diapers
Children who are not potty-trained need tightly fitted rubber pants or swim diapers. Regular diapers are not permitted in the pool.
🦺 Life Jackets
Life jackets must be U.S. Coast Guard approved. Do not assume ordinary inflatable swimming aids are permitted.
🍕 Outside Food
Outside food, beverages, glass containers and coolers are prohibited inside. An outside picnic area can be used, with re-entry available using the district’s receipt or hand-stamp process.
🚿 Shower First
The pool rules require every person to shower before entering the pool deck during open-swim hours.
🛟 Pool Toys
Rafts, inflatable swimming devices, snorkels, kickboards and noodles are not allowed during open swim. Some smaller toys are subject to management discretion.
⏱️ Safety Breaks
Safety breaks are conducted every hour for 15 minutes. Adults aged 18 and older may swim during the break.
What Should You Bring?
Before You Leave Home: 7-Step Oasis Plan
Oasis uses different pre-season, full-season and post-season schedules.
If conditions are cold or stormy, call the pool before starting the journey.
Do the pass calculation before accumulating daily admissions.
The 48-inch rule materially changes slide and spray-pad planning.
Bring proper swimwear, swim diapers where needed and only approved flotation equipment.
Children under 12 need an adult 18+, while younger children need especially close supervision.
Keep 847-967-6648 available for same-day weather and operating updates.
Accessibility: What Is Verified?
The Oasis pool rules state that individuals with disabilities needing wheelchairs on deck or flotation devices in the water will be accommodated.
That statement is useful, but it does not answer every access question. The published rule does not by itself confirm details such as a particular pool-entry lift, accessible changing configuration, transfer method or assistance needed for an individual attraction.
Verified
Accommodation is stated for visitors with disabilities needing wheelchairs on deck or flotation devices in the water.
Confirm Before Travel

Common Oasis Planning Mistakes
Using full-season hours in September
The 11:00 AM–8:00 PM daily schedule does not run through the entire season.
Promising every child all three slides
Two slides have a 48-inch minimum. Attraction access should be checked before the visit.
Buying daily tickets before considering a pass
Daily admissions are not later credited toward the pool-pass purchase price.
Bringing a family cooler inside
Outside food, beverages and coolers are restricted. Use the external picnic-area option instead.
Assuming bad weather means a refund
The published inclement-weather closure policy says no refunds or rain checks are issued.
