Best Water Parks in Massachusetts (2026)
People don't fly to Massachusetts for water parks, and I get why. This is a beach and history state first. But it has a genuinely interesting mix of them, and after years of visiting parks all over the country, I've learned the small states often hide the most character. Massachusetts is one of those.
You've got two year-round indoor parks near Boston and on Cape Cod, a couple of old-school seasonal outdoor parks that locals grew up on, a Six Flags water park with a pricing catch you need to know about, and a Cape Cod newcomer. I started out working the wave pool at Oceans of Fun in Kansas City, so I have a soft spot for the family-run places on this list, and Massachusetts has a few of those left.
Here's the quick table, then my straight take on each. Every price is what I could verify for the 2026 season.
| Park | City | Type | Adult price |
|---|---|---|---|
| Wicked Waves Water Park | West Yarmouth | Outdoor | ~$45 |
| Great Wolf Lodge New England | Fitchburg | Resort | From $40 |
| Water Wizz | East Wareham | Outdoor | $39.99 online |
| Breezy Picnic Grounds Waterslides | Douglas | Outdoor | $20 weekday |
| Fins Up! Water Park at Margaritaville Cape Cod | Hyannis | Resort | Varies |
| Six Flags Hurricane Harbor | Agawam | Outdoor | Varies |
| Water Park of New England | Danvers | Indoor | Varies |
Water Wizz, East Wareham
Water Wizz on the Cape Cod Canal in East Wareham is the classic seasonal outdoor park in this part of the state, and it's the one I'd point a family to first for a straightforward slide day. The pricing is honest and it rewards planning. General admission is $39.99 online versus $54 at the gate, guests under 48 inches and seniors are $37.99 online versus $44 at the gate, and there's an after-3 p.m. rate of $37.99 online.
:::tip{title="The online gap is the whole game"}
At most seasonal Massachusetts parks, the gate price and the online price are far apart. Water Wizz is the clearest example, but the same habit pays off elsewhere. Buy before you arrive at waterwizz.com and skip the gate premium entirely.

It's a summer-only park, so plan it for the warm stretch. On the Cape, this is the standby that families come back to year after year.
Great Wolf Lodge New England, Fitchburg
Great Wolf Lodge New England in Fitchburg is the year-round indoor option within reach of Boston, and the indoor part is the entire point. The water park is kept at 84 degrees, so a February visit feels the same as a July one. It's included free with a resort stay, which is how most families do it.
If you're not staying over, public day passes start at $40. They're priced dynamically by date and they can sell out, so a busy Saturday will cost more and may close to day guests entirely. It's one per-person price for ages 3 and up, and under 2 is free. Book and check live rates at greatwolf.com/new-england. For a winter-break trip with younger kids, this is the most reliable pick in the state, since weather never enters the equation.
Six Flags Hurricane Harbor, Agawam
Six Flags Hurricane Harbor is the water park attached to Six Flags New England, and it has the most important pricing catch on this entire list. Read this part carefully.
:::warning
In 2026 Hurricane Harbor is not included with standard Six Flags New England admission. Your daily park ticket is not valid for the water park. Getting in requires a water-park add-on starting around $10 on top of park admission, which starts around $39 online, or a 2-day combo priced around $25 per day, or a season pass. There is no standalone single-day water-park price, which is why the table above reads varies. Confirm the current add-on before you buy anything.
:::
Season runs late May through early September. If you're going to Six Flags New England anyway and the kids want slides, budget for the add-on up front so it isn't a surprise at the gate. Current details are at sixflags.com/newengland/hurricane-harbor.
Wicked Waves Water Park, West Yarmouth
Wicked Waves Water Park in West Yarmouth is the Cape Cod outdoor park, and it's structured a little differently from the others. Its passes are sold by type rather than by age. The published tiers run roughly $45 for the water park, around $30 for the inflatable park only, and about $60 for a combo. Those are sold through a ticket portal that shifts by date, so treat them as approximate rather than fixed, and there's no separate age-based child rate posted.
It's a summer seasonal park, and the split between the water park and the inflatable-aqua-park side means you should decide up front what your crew actually wants so you're not overpaying for a combo you won't use. On a hot Cape day, the water-park tier alone is usually the right call.
Fins Up! Water Park at Margaritaville Cape Cod, Hyannis
This one comes with a name change. The old Cape Codder Resort in Hyannis is now the Margaritaville Resort Cape Cod, and its indoor water park, formerly the Cape Codder Water Park, now operates as Fins Up! Water Park at 1225 Iyannough Rd. Our directory still carries the older Cape Codder listing, so that's the same place under its previous name.
It offers both daily and annual passes, but the resort doesn't publish prices on its site, so I've left the adult rate as varies rather than guess at a number I can't verify. For a Cape Cod trip where the weather turns, an indoor park in Hyannis is a useful backup. Check current rates directly with the Margaritaville Resort Cape Cod before you plan around it.
Water Park of New England, Danvers
Water Park of New England in Danvers is the indoor park north of Boston, and it's another rename. Longtime North Shore families knew it as CoCo Key. It now operates as Water Park of New England at the DoubleTree by Hilton Boston North Shore at 50 Ferncroft Rd, open year-round.
Day-pass prices are sold through an external booking system and aren't published on the site, so the adult rate is listed as varies. As an indoor, year-round option close to Boston, it fills the same role as Great Wolf for North Shore families who want a shorter drive, just at a smaller scale.
Breezy Picnic Grounds Waterslides, Douglas
I'm ending on this one because it needs the most context, and it's a story I find kind of moving. Breezy Picnic Grounds Waterslides in Douglas ran its three main waterslides for 42 years, and after all that time those slides have been retired. What's there now is lake swimming, a kiddie slide, and the picnic grounds. It is no longer a full waterslide park, and I'd feel bad sending a family expecting the old setup.
As it stands, admission is $20 on weekdays for ages 5 and up and $15 for ages 2 to 4, seniors, and military, rising to $22 and $17 on weekends. It's open daily 9 to 5 in summer. If you want a relaxed lake-swimming and picnic day rather than a slide day, it still delivers exactly that, and it's a good value for it. Just go in knowing what it is in 2026.
Picking your Massachusetts park
Here's how I'd sort it out:
- Best straightforward slide day: Water Wizz in East Wareham. Buy online.
- Year-round or bad weather: Great Wolf Lodge in Fitchburg, or Water Park of New England in Danvers for the North Shore.
- Cape Cod trip: Wicked Waves for outdoor slides, or Fins Up! in Hyannis if the weather turns.
- Already going to Six Flags: Hurricane Harbor, but budget the add-on in advance.
- Relaxed lake and picnic day: Breezy in Douglas, now that the big slides are gone.
:::key
Massachusetts is a small water park state that rewards knowing the details. Water Wizz is the cleanest outdoor value, Great Wolf covers the whole calendar indoors, and Six Flags Hurricane Harbor now needs a paid add-on that catches families off guard. Two parks changed names and one retired its slides, so this list reflects what's actually true on the ground. Prices were verified for the 2026 season.
