Big Sky Waterpark Ticket Prices 2026
Big Sky uses height-based day-ticket pricing rather than simply adult and child admission. Seniors age 60+ use the same published rate as guests under 48 inches.
| 2026 Ticket | Under 48″ / Senior 60+ | 48″ & Taller | Non-Rider |
|---|---|---|---|
| Full-Day Pass | $45 | $55 | $45 |
| Twilite Pass after 3 PM | $38 | $45 | $38 |
| Age 2 & Under | Free | — | — |
What Is a Non-Rider Ticket?
Big Sky defines a non-rider as a spectator who does not use the waterslides or hot tub. A non-rider supervising a small child may use the wading pool.
The park lists the normal non-rider admission first, then provides a $10 refund when the non-rider leaves with the wristband still attached and dry.
Can You Save With a Coupon?
The official 2026 admission page promotes a printable $4 admission coupon. Big Sky also lists AAA/AMA and active-duty military discounts. Check the exact current coupon terms before relying on a discount in your family budget.
Military Discount
Big Sky says an active military member and immediate family can receive $4 off admission with active military ID.
Birthday Admission
The official pricing page states that the birthday person can be admitted free when hosting a birthday visit at the park with at least three paying guests, subject to the park’s current birthday terms.

Big Sky Waterpark Hours 2026
Big Sky did not operate every day of the week during 2026. The official calendar is much more useful than assuming “summer means daily operation.”
| 2026 Period | Open Days | Hours | Important Detail |
|---|---|---|---|
| Opening Weekend | June 20–21 | 11 AM–6 PM | Opening weekend was listed as subject to change. |
| June 24–28 | Wednesday–Sunday | 11 AM–6 PM | Monday and Tuesday were closed. |
| July | Generally Wednesday–Sunday | 11 AM–6 PM | Mondays and Tuesdays were closed. |
| Aug. 1–23 | Generally Wednesday–Sunday | 11 AM–6 PM | Monday and Tuesday closures continued. |
| Aug. 24–28 | Closed | — | Do not assume normal late-August weekday operation. |
| Final Day | Saturday, Aug. 29 | 11 AM–Close | Official calendar did not list a numeric closing time. |
Why Monday and Tuesday Matter
Big Sky’s FAQ specifically tells visitors that the park is closed Mondays and Tuesdays and directs guests to the official calendar. This is one of the most important details for Glacier-area travelers, because a vacation itinerary can easily place a waterpark day on a closed weekday.

Big Sky Waterpark Slides & Attractions
Big Sky is built around a hillside layout, so expect stairs and elevation changes for major slides rather than one compact flat splash-pad-style facility.
Geronimo Speed Slide
Thrill 48″ minimumGeronimo is the park’s seven-story speed-slide attraction and one of the most important rides to check first for older children and thrill seekers.
Twister Slides
4 body slidesFour twisting body slides descend the hillside and finish in an approximately four-foot catch pool.
Big Splash River Ride
River rideA faster river-style water attraction promoted as a rapids experience rather than a calm lazy river.
Shredder Xtreme
Family thrillBig Sky describes Shredder Xtreme as a family thrill ride, making it useful for groups that want a shared attraction rather than only single-rider slides.
Kids’ Activity Pool
Younger visitorsA lower-intensity option for children who are not ready for Big Sky’s major hillside slides.

Several attractions use height restrictions, including Geronimo.
Metal snaps, rivets and buttons can violate slide rules.

Big Sky permits outside food and non-alcoholic drinks.
That can eliminate the $10 spectator refund.
