But even if it’s a cold day, as it so often is in the Granite State, that’s okay! There are several indoor water parks in New Hampshire as well. No matter whether it’s snowing or there are frigid winter temps, you can still enjoy good times on a water slide!
New Hampshire is home to the largest water park in New England — that would be Water Country — as well as several small niche outdoor and indoor water parks, from southern New Hampshire all the way into the White Mountains. There are even two indoor water park resorts.
Here are the best outdoor and indoor New Hampshire water parks.
Water Country is the largest water park in New Hampshire – and all of New England!

Outdoor Water Parks in New Hampshire
Water Country is not only the largest water park in New Hampshire, it’s the largest water park in New England! Its convenient location right off the highway in Portsmouth makes it popular with kids and adults of all ages (and easy day trip from neighboring states). Here you have enough thrill rides and easygoing rides that there’s something for everyone.
Water Country is known for its wide variety of water rides. Some thrill rides include Dr. Von Dark’s Tunnel of Terror, and a 58-foot slide called the Patriot; you’ll also find more moderate rides like the Adventure River, a lazy river flowing around the park, New England’s largest wave pool, and Thunder Falls and Wild Canyon, a fun and easygoing slide for groups of up to four.
Have young kids? Water Country has stuff for them, too, including kid-friendly areas like Olly Octopus and Pirate’s Pool and Lagoon.
Opening season: Water Country is open from late June through early September.

Castaway Island at Canobie Lake Park
Castaway Island is the water park within Canobie Lake Park in Salem, a fun theme park for the entire family. While it might not get as much attention as Canobie’s roller coasters like the Yankee Cannonball, Castaway Island is perfect on a warm summer day!
Head to the amusement park for a few hours, then cool off in the water park or spend a day in each for the ultimate experience. We recommend hitting up the Boston Tea Party flume ride as the perfect transition between dry and wet!
The most popular ride at Castaway Island is the tidal river, a lazy river with waves. There are also three slides at the top of a 60-foot tower. Children will enjoy the Lil’ Squirts Lagoon and the Rain Fortress, where you can shoot water cannons and stand under a tipping bucket.
Opening season: Castaway Island generally opens in June and closes after Labor Day weekend.
Whale’s Tale Water Park
Whale’s Tale Waterpark is a small water park with a lot of personality. This water park is located in Lincoln, a stone’s throw from Franconia Notch and what feels like a million fun family activities! We also think Whale’s Tale has one of the most scenic settings, surrounded by glorious mountains.
Fun rides here include Akua Beach, which provides waves for riders to surf or body surf. The Eye of the Storm takes you through a dark tunnel before you’re shot out into a swimming pool.
There are also several slides, pools, and other rides to enjoy. On Poseidon’s Voyage, the floor falls out from under you and you slide until you reach the water!
Opening season: Whale’s Tale opens in mid-June and closes in early September.

You don’t have to wait until December to get into the holiday spirit in New Hampshire! Santa’s Village is a delightful Christmas-themed park in Northern New Hampshire, and part of the park is home to Santa’s Water Park.
While Santa’s Village is often compared to Story Land, a lovely kids’ theme park in Glen, Santa’s Village is the only one to feature a water park. Water rides include Ho Ho H2O, where you can climb, slide, and splash in hopes of avoiding the bucket of water that dumps out every few minutes. Joy Ride Slides has three twisting and turning slides you can speed down.
Polar Paradise has pools, slides, and spray zones for the whole family to enjoy. Poogee’s Splash Pad is perfect for young kids to jump around and enjoy the gentle water splashes.
Of course, the water park is only part of Santa’s Village, so make time for the dry activities, too! And hit up the gift shop for a Christmasy souvenir you’ll treasure.
Opening season: The water park area at Santa’s Village opens in late May and closes in early October, though other parts of the park are open through the Christmas season.
