This Massive Massachusetts Indoor Waterpark Resort Has Slides, Pools, And Endless Family Fun

Picture this: snow is falling outside, the wind is howling, and you’re floating in a tube through warm water in a swimsuit. That’s a perfectly normal winter day at one of the biggest indoor water parks in Massachusetts.

Behind a set of glass doors, you’ll find 65,000 square feet packed with water slides, splash pads, warm pools, and plenty of happy screams. Four- and five-story slide towers rise overhead, while a giant bucket dumps hundreds of gallons of water onto the play area every few minutes.

Little swimmers can watch movies on a huge sail screen while splashing in shallow water. Older kids can race across floating lily pads, play basketball in the pool, and explore a colorful coral reef-themed area.

Adults have their own quieter retreat with hot tubs that connect the indoor and outdoor areas.

When everyone needs a break from the water, there’s an arcade, a grille, and an attached hotel, so you can turn the visit into a full weekend without getting back in the car.

Danvers Hides A Water World Behind Glass Doors

Locals still call it Coco Key out of habit, even though the sign now reads Water Park of New England. Whatever name you grew up with, the address hasn’t moved.

Step through the doors and the scale hits first. Sixty-five thousand square feet, all of it indoors, all of it heated, with slide towers climbing four to five stories overhead until the ceiling barely seems real from the pool deck.

Hours shift by season, so it pays to check before you load the car. In summer, doors open at 11 AM Wednesday through Sunday and close at 7 PM.

The rest of the year, the schedule tightens to Friday 4 PM–9 PM and Saturday–Sunday 11 AM–7 PM.

Tourists often say mornings feel calmer, with shorter slide lines and easier seating. Afternoons fill up fast, especially on snowy weekends.

So, would you rather chase the quiet morning shift or jump into the busy afternoon energy?

Four Slides, One Tall Tower

Climb the stairs and your legs will tell you exactly how tall this tower is. Four to five stories of steps lead to four different slides, each with its own personality.

Two of them are tube slides. Barracuda Blast runs completely dark, so you have no idea which way you are turning.

Pelican Plunge glows with light, giving you a front row look at every dip.

Feeling braver? The body slides skip the tube entirely.

Shark Slam is pitch black from top to bottom. Gator Gush is semi translucent, letting a soft glow follow you down.

Both build real speed and push hard through the turns.

Here is a trick riders love. Tube slides can be taken backward, which scrambles your sense of direction in the best way.

First timers usually scream, then immediately climb back up.

Riders must be at least 48 inches tall for the main tube and body slides. Measure your kids before the trip so nobody gets disappointed at the top of the stairs.

Water shoes are a smart call for the walk between attractions, since pool decks stay wet all day long. Many visitors to this Massachusetts park pack a pair just for the stairs.

Which one calls your name first, the dark drop or the glowing one?

Parrot’s Perch Splash Playground

Every few minutes, a bell sound cuts through the noise and everyone under four feet tall starts running. That means the giant bucket at the top of Parrot’s Perch is about to tip.

Hundreds of gallons crash down all at once. Kids stand right underneath it on purpose, arms raised, grinning like they just won something.

The structure itself climbs several levels, painted bright and packed with things to pull, spray, and climb. Water cannons let kids aim at each other, at parents, at absolutely nobody in particular.

Smaller open topped slides twist off the sides, sized for shorter riders who cannot handle the big tower yet. No height rule locks them out here, which makes it a favorite for six and seven year olds.

Tourists often describe the whole thing as a jungle gym with plumbing, and that is a fair picture. Parents tend to claim a nearby seat, since chairs disappear quickly once the crowd builds.

Life jackets are provided free, and there is no shame in strapping one on a nervous swimmer. Lifeguards keep a close watch from the deck.

Bring a waterproof phone pouch if you want photos of the bucket drop. It is the shot everyone shares later.

Can your family stay put when that bucket finally lets go?

Movies While Toddlers Splash

Toddler parents, this corner was built for you. The Dip-In Theater is a dedicated zone for little swimmers under 48 inches tall, and it removes almost every worry from the day.

Water starts at zero depth, meaning the floor slopes in gently like a beach. No sudden drop, no scary edge, just a slow slide from dry to shallow.

Tiny slides sit low to the ground. Water spouts pop up from the floor.

Small dumping buckets sprinkle rather than crash, which suits kids who dislike surprises.

Then look up. A huge sail shaped screen plays movies right above the pool, so a toddler can sit in two inches of warm water and watch a film.

Plenty of grown ups admit they get pulled into the plot too.

Families with a one year old have reported a full afternoon of fun here, which says a lot about the design. Warm water helps, since chilly kids leave early.

Handy note. Children 24 months and older need their own admission, while babies 23 months and under come in free.

Pack a swim diaper, a hooded towel, and snacks for the ride home. Toddlers crash hard after a day like this in Massachusetts.

Lily Pads And Hoops

Older kids need a challenge, and Coral Reef Canyon delivers one. A line of floating lily pads stretches across the water, dangling rope overhead for balance.

The goal sounds simple. Cross without falling.

Almost nobody does it on the first attempt, and the splash is half the entertainment for everyone watching from the deck.

Water basketball takes over the other end. Hoops sit at pool level, so games turn into wet, laughing chaos rather than serious competition.

Strangers end up on teams together within minutes.

Behind it all, an animated coral reef backdrop covers the wall with fish and bright color. It gives the whole pool a tropical feel that is welcome in the middle of a Massachusetts winter.

Depth runs about three to four feet, deep enough for real swimming but manageable for confident kids. Weaker swimmers should grab a free life jacket before jumping in.

A tip from experienced visitors. Try the lily pads early in the day, before the line stretches and the pads get slick with traffic.

Goggles help too, since chlorine can sting sensitive eyes after a few hours of play.

Float The Adventure River

Not everything here demands courage. Coconut Grove Adventure River is the slow lane, and it is easily the most talked about attraction in the building.

Grab a tube, sit back, and let the current carry you in a loop around Parrot’s Perch. The ride takes you past the play structure, so you get a front row view of the action without doing any work.

Do not get too comfortable though. Splashy surprises wait along the route, and they arrive without warning.

Kids learn where they are and start dodging on purpose.

Grandparents love this ride. So do parents who spent the morning climbing five stories of stairs.

Warm water and a steady drift make it a genuine break.

Tubes go fast during busy hours, so keep an eye out when someone steps off. Arriving near the 11 AM opening usually means an easier grab.

Hold the tube handles and stay seated to avoid tipping, especially in spots where the current picks up. Lifeguards are stationed along the way if anyone needs a hand.

Riders often circle five or six times before they lose interest, which makes it the best value per dollar in the park.

Grown Ups Get Palm Grotto

Somebody in the family always plays lifeguard for the day. Palm Grotto is the reward for that person.

Reserved for guests 15 and older, this spa area holds oversized hot tubs and one clever feature. A swim through passage links the indoor section to the outdoor section, so you can glide from a warm room into open air without leaving the water.

Picture steam rising while snow lands on the deck around you. That contrast is the whole reason people talk about this spot at 50 Ferncroft Rd in Danvers, Massachusetts, long after they leave.

The age rule keeps things peaceful, which is exactly the point. Older teens can join, younger kids cannot, and the noise level drops noticeably compared to the main deck.

Timing helps. Late afternoon, after a few hours of slides and stairs, is when hot water feels best on tired shoulders.

Practical advice. Bring a towel to the edge so you are not walking far while wet, and step carefully, since the surrounding deck stays damp.

Parents often trade off, one adult watching the kids while the other soaks, then swapping halfway through. It works surprisingly well.

Would you spend your soak indoors, or float outside and let the cold air hit your face?

Arcade, Food, And Hotel

Wrinkled fingers eventually need a break, and the park has a plan for that. Key Quest Arcade sits just steps from the water, packed with games for every age group.

Claw machines, racing seats, ticket games. Visitors generally find the game prices reasonable, which is a nice change of pace.

Give each kid a set budget and the whole thing runs smoothly.

Hungry? The Breezeway Grille handles lunch inside the park with pizza, chicken fingers, and other quick options.

Outside food and beverages are not allowed in, so plan on eating on site or heading back out to your car, since re-entry is permitted.

Now the best part of the whole setup. The park connects directly to the DoubleTree by Hilton Boston North Shore, so a weekend stay means no driving, no parking, no cold walk in a wet swimsuit.

Changing rooms with showers are available, plus security lockers for daily rental. Complimentary towels come from Rusty’s Dive Shop, and life jackets are free too.

Twilight tickets cost less for shorter evening hours, a smart choice for families who want a couple of hours instead of a full day in Massachusetts.
