If you grew up anywhere near the Tri-State area, the mere mention of a Vernon NJ water park probably triggers a very specific set of sensory memories. You likely think of the smell of sunscreen mixed with mountain air, the feeling of cold spring water hitting your face, and that slightly terrifying adrenaline rush that comes from sliding down a literal mountain. We’re talking about Mountain Creek Waterpark. It’s a place that has lived through multiple identities—Action Park, Mountain Creek, back to Action Park, and back again—but the soul of the place remains fundamentally different from your average corporate splash pad.
It’s built into the side of a mountain.
That’s the thing people forget until they’re actually there, staring up at a hiking trail disguised as a walkway to the next slide. Most water parks are flat concrete expanses with plastic towers. This place is rugged. It’s rocky. Honestly, it’s a workout just as much as it is a vacation. You’ll see people huffing and puffing their way up to the High Anxiety tube ride, and by the time they reach the top, they’ve earned that drop.
The Action Park Legacy and Why Vernon NJ Water Park History Matters
You can’t talk about the current park without acknowledging the ghost of Action Park. It’s legendary. It’s the stuff of documentaries like Class Action Park. Back in the 70s and 80s, the park was infamous for being a bit of a "wild west" of amusement. Gene Mulvihill, the man behind the original vision, basically decided that safety regulations were more like suggestions. He wanted people to have "control" over their thrills. That led to the Alpine Slide, the Cannonball Loop (yes, the one with the literal vertical loop that didn't stay open long), and a reputation for being the world's most dangerous theme park.
Today? It’s safe. Really.
The modern iteration of this Vernon NJ water park is highly regulated, staffed by alert lifeguards, and checked by state inspectors. But that "edge" hasn't entirely vanished. Unlike a Disney park where everything is polished and sanitized, Mountain Creek still feels like you’re playing in the woods. The water is often sourced from the mountain itself, meaning it’s crisp—or "freezing," depending on who you ask—and the terrain is naturally uneven. It keeps that spirit of adventure alive without the legitimate peril of the 1980s.

The Rides That Actually Live Up to the Hype
Most people head straight for the big names. Bomb Bay is the one everyone talks about. You stand in a capsule, the floor drops out, and you fall vertically. It’s over in seconds, but those seconds are intense. Then there’s the H2-Oh-No, which is a 99-foot drop. If you have any fear of heights, this is where you’ll face them.
But the real gems are the ones that use the mountain's natural slope.
- The Colorado River: This isn't a lazy river. Far from it. It’s a group raft ride that winds down the mountain through trees and rock formations. You’ll get splashed, you’ll probably bump into the sides, and you’ll definitely get some side-eye from the person in your raft who didn't want their hair to get wet.
- Surf Hill: An eight-lane mat racer. It’s simple, but because of the way the humps are designed, you actually get some decent airtime if you're heavy enough. It's the ultimate spot for family rivalries.
- The Cliff Jumps (Canyon Cliffs): This is a Vernon staple. It’s exactly what it sounds like. You jump off a ledge into a deep pool of mountain water. There are no slides, no tubes, just gravity. It’s surprisingly intimidating when you’re standing on the edge looking down at the crowd waiting for you to just go already.
Honestly, the "Lazy River" here is one of the few things that actually feels relaxed, but even then, you’re floating past granite walls. It’s a vibe. You aren't just at a park; you're in the Highlands.
Survival Tips: What Most People Get Wrong About a Day in Vernon
Look, I’ve seen enough people ruin their day here to know better. First off: footwear. Do not, under any circumstances, think you can do this park barefoot. The paths are paved, often hot, and consistently steep. You need water shoes with actual grip. I’ve seen people try to navigate the uphill treks in cheap flip-flops only to have them snap halfway to the top of the Thunder Run. It’s a long walk back down with a broken sandal.
Parking is another thing. There’s the main lot, which fills up fast, and then there are the overflow lots. If you arrive at noon on a Saturday in July, expect to spend twenty minutes just getting from your car to the gate.

Pro tip: Go on a Tuesday. If you can swing it, a weekday is a completely different experience. The lines for the big slides go from an hour-long sweat-fest to a five-minute breeze. Plus, the locker situation is much less of a headache. Speaking of lockers—rent one. Don't be the person trying to hide your car keys inside a rolled-up towel under a lounge chair. People know that trick.
The "Cold Water" Factor
Let's be real for a second. The water here is not heated. On a 95-degree day in August, this is a godsend. It’s refreshing, it’s bracing, and it wakes you up. However, if you go in early June or late August when the air temperature dips, that first plunge into the Canyon Cliffs pool will take your breath away. Literally. Your chest will tighten. It’s part of the "Mountain Creek experience," but if you're sensitive to cold, maybe wait for a heatwave.
The kids' areas, like Splashdown and Lost Island, are a bit more manageable for the little ones, but even there, the water has that mountain chill. Most kids don't care, though. They’ll turn blue before they admit they’re cold.
Eating and Drinking (Without Going Broke)
The food is standard fare. Burgers, fries, chicken tenders, and overpriced soda. It’s not winning any Michelin stars. Most families opt to leave a cooler in the car and head out to the parking lot for a "tailgate lunch" to save forty bucks. The park allows re-entry, so you can stamp your hand, go eat a sandwich in the AC of your SUV, and come back.
If you do eat inside, the Biergarten area is actually pretty decent for the adults. It’s got a bit more shade and a better selection of drinks than the standard snack stands. Just remember that sliding down a 100-foot drop after three craft IPAs is a recipe for a very bad afternoon.

Is the Triple Play Season Pass Worth It?
If you live within an hour of Vernon, usually yes. The price of a single-day ticket can be steep—often hovering around $40-$60 depending on when you buy. The season passes or the "Triple Play" cards (which usually offer three visits for a discounted rate) pay for themselves almost immediately.
Also, keep an eye on the weather. Because the park is in the mountains, storms can roll in fast. If there’s lightning within a certain radius, they clear the water. Sometimes these storms pass in twenty minutes; sometimes they wash out the day. They don’t usually offer refunds for weather unless the park closes early, so check the radar before you make the drive up Route 23.
Beyond the Water: Why the Location Matters
Vernon isn't just the water park. It’s an outdoor hub. If you’re making a weekend of it, you’ve got the Appalachian Trail right there. You’ve got the Mountain Creek Bike Park (which is world-class for downhill mountain biking) sharing the same footprint. In the winter, this is a ski resort.
This duality is why the Vernon NJ water park feels so different. The infrastructure serves two masters. The lodges that hold skiers in January are the same ones holding sunburnt teenagers in July. This gives the whole place a rugged, lodge-style aesthetic that you just don't get at a Great Wolf Lodge or a Six Flags Hurricane Harbor.
Final Take: Should You Go?
If you want a relaxing, pampering day where you barely lift a finger, maybe look elsewhere. But if you want a day that feels like a genuine New Jersey adventure—complete with steep climbs, freezing water, and legitimate thrills—Mountain Creek is the place. It’s a rite of passage. It’s the place where you prove you’re brave enough to jump off a cliff or drop through a trap door.
It’s messy, it’s hilly, and it’s a little bit exhausting. But honestly, that’s exactly why it’s stayed popular for decades.
Actionable Next Steps for Your Visit
- Buy tickets online in advance. You will save money compared to the gate price, and it makes the entry process significantly faster.
- Invest in "real" water shoes. Look for ones with rubber soles. Your feet will thank you after the third time you climb the hill to the top of the Gauley.
- Arrive 30 minutes before opening. The first hour of the park is the "golden hour" where you can hit the most popular slides (Bomb Bay and H2-Oh-No) without a massive wait.
- Check the "Mountain Creek" social media or website for closures. Sometimes specific rides are down for maintenance, and it’s better to know before you get the kids hyped up for a specific slide.
- Pack a "transition bag." Keep dry clothes, a brush, and extra deodorant in the car. The humidity and mountain air do a number on you after six hours in the sun.
The reality of visiting this Vernon NJ water park is that it’s what you make of it. If you embrace the "mountain" part of Mountain Creek, you’ll have a blast. If you expect a flat, easy walk, you’re going to be frustrated by lunch. Wear the right shoes, stay hydrated, and maybe don't look down before you jump off the cliff.
