The first time my daughter launched down the blue speed slide at Last Chance Splash Waterpark, her scream of pure joy echoed across the entire facility—and I knew we’d be coming back every summer.
Tucked away in Montana’s capital city of Helena, this community gem offers exactly the kind of refreshing escape that Big Sky Country families and visitors crave during those surprisingly hot July and August days.

What Makes Last Chance Splash Special
I’ve visited waterparks across Montana, from Electric City Water Park in Great Falls to smaller splash pads scattered throughout the state. Last Chance Splash occupies a unique middle ground—it’s substantial enough to spend an entire day enjoying, yet intimate enough that you never feel overwhelmed or lost in the crowds.
What struck me most during my visit last summer was how genuinely well-maintained everything appeared. The concrete was clean, the water sparkled crystal clear, and the lifeguards seemed alert and engaged rather than bored teenagers scrolling through their phones.
The name “Last Chance” pays homage to Helena’s gold rush history—Last Chance Gulch was where prospectors made their final attempt at striking it rich. Today, this waterpark gives families their own kind of treasure: affordable summer fun in a state where entertainment options can sometimes feel limited.
The Complete Breakdown of Attractions and Features
The Water Slides
The slides at Last Chance Splash cater to different comfort levels, which I appreciated as a parent with one thrill-seeking kid and one more cautious swimmer.
The main attraction is a pair of body slides that twist down from a platform roughly 25 feet high. The blue slide offers a faster, more direct descent, while the yellow slide incorporates more curves and feels slightly gentler. During my visit, the lines for these slides averaged about 5-10 minutes during peak afternoon hours—totally manageable.
There’s also a shorter, wider slide that younger children can enjoy. This one empties into a separate splash area, so parents don’t need to worry about little ones getting knocked over by bigger kids at the landing zone.
I’ll be honest—if you’re expecting massive tube slides or those intense drop slides you’d find at a major resort, you’ll need to adjust your expectations. But for a municipal waterpark, the slide selection is solid.
The Lazy River
This was my personal favorite feature. After chasing kids around all morning, floating along the lazy river with the warm Montana sun on my face felt absolutely therapeutic.
The lazy river at Last Chance Splash isn’t particularly long—maybe a three-minute circuit—but it’s well-designed with a consistent current and enough depth to actually float rather than constantly scraping bottom. They provide tubes at no extra charge, which I’ve found isn’t always the case at other facilities.
Pro tip: the lazy river gets crowded in the afternoon. If you want a peaceful float, aim for the first hour after opening or the last hour before closing.
The Main Pool and Lap Lanes
The central pool area is where most families congregate. It features a gradual entry (zero-depth area) that’s perfect for toddlers, gradually deepening to about 5 feet at the far end.
What I appreciated was the clear separation of spaces. The lap lanes run along one side, cordoned off for serious swimmers who don’t want to dodge kids doing cannonballs. When I visited, there were always at least two lanes available, even during busy periods.
The pool maintains a consistent temperature—warm enough to be comfortable but not so warm that it feels like bathwater. I’d estimate somewhere in the low 80s Fahrenheit.
Splash Pad Area
For families with toddlers and preschoolers, the splash pad section is worth the price of admission alone.
Ground-level sprayers, gentle fountains, and interactive water features keep little ones entertained for hours. There’s a small dump bucket that fills and tips periodically, creating delighted chaos among the waiting children below.
The splash pad has rubberized flooring, which provides better traction and softer landings than concrete. I watched my nephew, who’s admittedly a bit clumsy, take several tumbles without a single tear.
Diving Boards
Two diving boards—one standard height and one low board—serve swimmers who want to practice their jumps. The deep end where the boards are located is genuinely deep (about 12 feet), and lifeguards enforce strict one-at-a-time rules.
During my observation, the diving area attracted mostly tweens and teenagers perfecting their cannonballs and attempting increasingly creative jumps.

Insider Tips From Someone Who’s Actually Been There
Timing Your Visit
If you have flexibility, Tuesday through Thursday mornings are golden. I visited on a Wednesday last July, arriving right at noon when the gates opened, and had nearly free reign of the slides for the first hour.
By 2 PM, the park was noticeably busier. By 3 PM on weekends? Expect lines at every attraction and competition for lounge chairs.
Late afternoon (after 5 PM) is another sweet spot. Families with young children start heading home for dinner, and the crowds thin considerably.
The Shade Situation
This is important: natural shade is limited at Last Chance Splash. There are some shade structures near the splash pad and a covered picnic pavilion, but prime shaded spots near the main pool go fast.
I recommend arriving early specifically to claim a spot under one of the umbrellas or shade sails. Alternatively, bring a sun hat and plenty of reef-safe sunscreen—you’ll be reapplying throughout the day.
Food and Concessions
There is a concession stand on-site offering standard waterpark fare: hot dogs, nachos, soft pretzels, ice cream bars, and drinks. Prices are reasonable by waterpark standards—I paid around $4 for a hot dog and $2 for a bottled water during my visit.
That said, bringing your own lunch and snacks makes economic sense for families. The picnic area is perfectly adequate, and you can always supplement with concession treats.
Locker and Storage Options
Small lockers are available for rent near the entrance. I always spring for a locker to store car keys, wallet, and phone rather than worrying about them on a towel by the pool.
The lockers require quarters (bring several), so stop by a gas station beforehand if you only have cards.
Who Last Chance Splash Is Perfect For
Based on my experience and observations, this waterpark is ideal for:
- Families with children under 12 — The variety of attractions and safety-first approach makes it welcoming for younger kids
- Helena residents looking for a season pass — Locals who visit multiple times per summer get excellent value
- Travelers passing through central Montana — It’s a perfect half-day stop to break up a road trip
- Anyone seeking affordable entertainment — Under $30 for a family of four represents real value
It may be less ideal for:
- Thrill-seeking teenagers — The slides are fun but not extreme
- Visitors expecting a mega-resort experience — This is a well-run municipal facility, not a Schlitterbahn
How Last Chance Splash Compares to Other Montana Water Attractions
Montana doesn’t have an abundance of waterparks, which makes each one valuable in its own right.
Compared to Oasis Waterpark in Great Falls, Last Chance Splash offers a more intimate experience with shorter lines. However, if you’re looking for more attractions and don’t mind bigger crowds, Ridge Waters Water Park in Butte provides additional slide options.
For families with very young children, Castle Rock Splash Park offers a completely free alternative focused on splash pad-style play, though it lacks the pools and slides that make Last Chance Splash a fuller experience.
What Last Chance Splash does better than most is balance—it has enough to keep everyone entertained without feeling overwhelming or overpriced.
Exploring Helena While You’re There
One of the advantages of Last Chance Splash’s location is that Helena itself offers plenty to do before or after your waterpark visit.
Walking Mall Downtown
The Last Chance Gulch pedestrian mall is a charming few blocks of local shops, restaurants, and historic architecture. It’s about a 10-minute drive from the waterpark and makes for a pleasant post-swim stroll.
I especially enjoyed grabbing ice cream at one of the downtown shops after our waterpark day—a perfect wind-down for tired kids.
Mount Helena City Park
If you’re traveling with older kids or active adults, the trails at Mount Helena offer stunning views of the valley. Obviously, save this for a different day than your waterpark visit—wet swimsuits and hiking don’t mix well.
Cathedral of St. Helena
This stunning Gothic Revival cathedral is worth a quick stop even if you’re not religious. The architecture is genuinely impressive, and the interior is cool and quiet—a nice contrast to waterpark chaos.
Where to Eat Nearby
Some personal favorites within a short drive of the waterpark:
- Bert & Ernie’s — Solid American fare with generous portions
- Steve’s Cafe — Legendary breakfast spot (arrive early)
- Taco del Sol — Quick, affordable, and satisfying Mexican
Where to Stay If You’re Visiting From Out of Town
Helena has a decent range of accommodation options to fit various budgets.
Budget-Friendly
Standard chain hotels along Prospect Avenue offer consistent quality at reasonable rates. I’ve stayed at the Super 8 and found it perfectly adequate for a family visit—clean rooms, free breakfast, and easy highway access.
Mid-Range
The Fairfield Inn and Hampton Inn provide more amenities including pools (though after a day at Last Chance Splash, you probably won’t need another pool).
Unique Options
For something more memorable, consider staying at a local B&B or renting a cabin outside town. The Sanders Bed and Breakfast occupies a beautiful historic mansion and offers an experience you won’t find at chain hotels.
Planning Your Visit: Day Trip vs. Extended Stay
Day Trip Itinerary
If you’re driving in just for the waterpark:
- Arrive 15 minutes before opening to get parking and secure a good spot
- Enjoy the slides and lazy river in the morning when it’s less crowded
- Break for lunch in the picnic area (brought from home or grabbed at concessions)
- Let kids burn off remaining energy in the splash pad
- Head downtown for dinner before driving home
Weekend Trip Itinerary
If you’re making a weekend of it:
- Day 1: Arrive in Helena, explore downtown, early dinner
- Day 2: Full day at Last Chance Splash (bring a cooler lunch)
- Day 3: Morning hike at Mount Helena, Cathedral visit, drive home
Accessibility and Special Considerations
Last Chance Splash makes reasonable efforts toward accessibility, though like many older municipal facilities, it’s not perfect.
The main pool has a zero-depth entry, making it accessible for wheelchair users who can transfer. There are accessible restrooms near the main building, and pathways throughout the facility are paved.
However, the slide towers require climbing stairs, and the lazy river entry involves steps. If you have specific accessibility needs, I’d recommend calling ahead to discuss what accommodations are available.
For guests with sensory sensitivities, note that the facility can get quite loud during peak hours with excited children, whistles, and the constant sound of splashing water.
Weather Considerations for Your Visit
Montana weather can be unpredictable, even in summer. A few things to keep in mind:
- Afternoon thunderstorms are common in July and August—the park will clear pools at the first sign of lightning
- Mornings tend to be cooler, sometimes in the 60s; the water may feel cold until you adjust
- Wind can pick up quickly, making shade structures and the lazy river less comfortable
- Extremely hot days (90°F+) bring everyone to the waterpark—expect crowds
I always recommend having a backup plan—maybe a visit to a Helena museum or lunch at a restaurant—in case weather forces an early departure.
Is Last Chance Splash Worth the Visit?
After spending multiple days at this waterpark over the years, my honest assessment: absolutely yes, with appropriate expectations.
This is not a destination waterpark you’d plan an entire vacation around. But as part of a broader Montana trip, or as a summer activity for families in the Helena area, it delivers exactly what you’d hope for—a safe, clean, well-run facility where kids can burn energy and adults can relax.
The pricing is fair. The staff is friendly. The attractions, while not extreme, are genuinely fun. And the setting—with Montana’s hills visible beyond the facility—reminds you that you’re somewhere special.
I think what I appreciate most is that Last Chance Splash feels authentically Montanan. It’s a community gathering place where locals share summer afternoons with visitors, where kids make friends in the lazy river, and where the pace feels refreshingly unhurried compared to mega-attractions in other states.
Final Thoughts and Recommendations
If you’re planning a visit to Last Chance Splash Waterpark, here’s my final advice:
- Visit mid-week if possible for shorter lines and more space
- Arrive at opening to claim a shaded spot
- Bring your own food to save money, but leave room in the budget for concession treats
- Apply sunscreen before arrival and reapply every two hours—Helena’s elevation means the sun is stronger than you’d expect
- Don’t skip the lazy river, even if you’re with teenagers who think it’s “boring”
- Consider the season pass if you’re local—it’s a genuine value
Most importantly, set your expectations appropriately. This is a lovely municipal waterpark that does exactly what it should: provide affordable summer fun in Montana’s capital city.
My family and I will be back again next summer. The scream of joy from that first slide ride? We’re chasing that feeling every year now. And honestly, that’s worth every penny of admission.
