Growing up in Massachusetts, summer always meant fun in or near the water. I spent many happy days splashing around at Breezy Picnic Grounds, a relaxed picnic area and beach on a reservoir in Douglas. My cousins and I wore ourselves out swimming and going down the waterslides again and again and again… our parents had done the same thing growing up and knew that a day at the beach there would result in a happy, quiet ride home.

In addition to many of the oceanside options, the Boston area has a fantastic selection of indoor and outdoor water parks with slides, rivers, pools, beaches, and more. Most locations have a selection of rides from slow and kid-friendly to speed slides or enclosed slides with hairpin turns, so everyone in your family will find something they enjoy.

And if you’re in Boston with small kids, there’s nothing like cooling off in the Boston Common Frog Pond Spray Pool!

Outdoor Water Parks in Massachusetts

Water Wizz

East Wareham, MA


In the 1980s, water parks were all the rage. Established in 1982, Water Wizz of Cape Cod, Inc. was the first company of its kind in New England, with four serpentine slides and two speed slides.

In 1984, Water Wizz grew by adding a mini golf course with 18 holes and bumper boats. In 1989, the longest tube ride in southern New England, known as “The Canal,” with a lazy river and food stands, opened to the public. Since then, many more attractions have been opened at Water Wizz, including fan favorites like Thunder Falls, with three thrilling tube rides. There are several beaches and playgrounds suitable for small children to play on.

Water Wizz was featured in the movie The Grown Ups. If it seems familiar, that’s probably where you know it from! Reviewers LOVE this water park, giving it overwhelmingly five-star ratings. Some reviewer tips: wear water shoes because the concrete can get hot, and rent a cabana so you and your group always know where to meet.

Opening Season: Water Wizz is open in July and August. Check the website or Facebook page for updates!

Six Flags New England (Hurricane Harbor)

Agawam, MA


Hurricane Harbor claims to be New England’s largest water park. They might be right since the water park has at least 15 attractions, a shop, cabanas, lockers, and more. There are multiple pools and slides for people of all ages, including several aimed at the younger crowd.

Reviewers say the Adventure River – a slow-moving 1,000-foot river best enjoyed from atop a tube – is a fun way to relax between the more exhilarating slides like the Tornado and Typhoon. The Big Kahuna offers four enclosed tube slides with unpredictable twists and turns. And for your little ones, Hook’s Lagoon offers lots of family-friendly splashing fun.

A word to the wise: a Six Flags New England ticket doesn’t automatically include admission to Hurricane Harbor. Buying your tickets online may result in a lower ticket price. The water park is an extra charge. Reviewers advise lines can be long on busy days, but if you attend on a weekday, you will see shorter lines for the rides.

Opening Season: The Hurricane Harbor Waterpark’s first day is Saturday, May 27, and the park opens at 11:30 a.m.

Cape Cod Inflatable Park

West Yarmouth, MA


Cape Cod Inflatable Park and Wicked Waves Water Park, located an hour and a half south of Boston, are more than just bounce houses and some slides. The biggest inflatable park in the United States features nearly two dozen attractions, and the water park boasts more than a dozen attractions for people of all ages. There’s also an arcade, food options, cabana rentals, and a temporary tattoo stand.

The Cape Cod parks contain too much to do in one day, according to the attraction’s website, and they have a solution for you: the Cape Cod Family Resort. If you book a stay at the resort, you’ll get free passes to the inflatable park – up to six passes as long as you book by phone or on their website.

Reviewers say younger children will love the entire experience at this “hidden gem” and will enjoy coming back again and again. Cabana rental offers some additional perks like chargers for your devices and extra space; reviewers also advise you should plan to bring your own towels and expect a long wait for food.

Opening Season: Cape Cod Inflatable Park opens Jun 10, 2023.

The waterslides suitable for smaller children are close to the beach and do not cost extra. Rates for entry are cheaper after 3 p.m. Kids can have hours of fun on the slides and beach while their parents relax on the grassy picnic area.

The beach and slides are always clean, and there are many shady spots to set up.

Umbrellas and the like are allowed at the Breezy Picnic Grounds – it’s a relaxed experience with plenty of staff and free parking.
