Get a well-earned respite from the summer heat at one of the water parks in and around New Hampshire. Here’s everything you need to know, from prices to dates.
This summer, we’re having fun and cooling down any way we can—bonus points if limited driving is involved, considering this year’s soaring gas prices. We’re eating ice cream, enjoying iced tea with our neighbors, and, yes, going for a dip. Thankfully, there are many ways to do the latter even if you don’t own a pool (or know a loved one who does). For example, you could enjoy some time at Canobie Lake Park, or you could beat the heat at one of New Hampshire’s best water parks.
New Hampshire is lucky to have several stunning water parks, each with its own crisp pools, roaring water slides, and refreshing treats to keep your fun summer day going. Here, we’re breaking down when they’re opening for the season, as well as how much they cost and what you can expect from them. That way, you can make the best decision for you and your loved ones.

The price of Kahuna Laguna Indoor Water Park might sound steep, but this aquatic attraction has a lot to offer. It’s open year-round thanks to being an indoor water park, which means you don’t need to wait for summer to officially start to dip your toes in warm, refreshing water. Kahuna Laguna Indoor Water Park is located at the Birchmont Resort and Spa, so you can make a full trip out of visiting it, but you don’t have to stay at the resort to purchase entry to the water park.
This water park has plenty of swimming space and several huge water slides. Plus, this park offers a few great discounts for entry. Tuesdays are BOGO day, meaning two people can gain entry for the price of one, and staying at some hotels in the area qualifies you for a 20% discount at entry.

Water Country Water Park has your usual suspects—pools and slides—and so much more. Here, you’ll find innovative and unique attractions like Hyperlight, a tube ride surrounded by galaxy-evoking colors and sounds, and Dragon’s Den, another tube ride that sees you coming face to face with a dragon in its circular lair, sloshing around before being dropped into total darkness.

Folks around Salem, rejoice: Castaway Island at Canobie Lake Park is set to open on May 23 this year. However, don’t plan any weekday outings just yet. Until June 19, the water park will be weekend-only, but once Juneteenth arrives, you can swim every day to your heart’s content. There are several water slides here, as well as the Rain Fortress for kids, which is as big and fun as it sounds.
One of the highlights of Castaway Island is its Tidal River. This unique attraction combines the typical wave pool and lazy river, giving you the best of both worlds. The waves gently usher you through the starting pool and subsequent river, letting you relax but also experience everyone’s favorite water-park thrill. If that weren’t enough, you can indulge in Dole Whip here without having to travel all the way to Disney World!
