Beware the "crocs" at Crocodile Run at Adventureland.
Adventureland — Farmingdale
2245 Broadhollow Road
Along with its thrilling roller coaster and Ferris wheel, this venerable Long Island amusement park boasts three exciting water rides—Adventure Falls, a popular flume ride for bigger kids with twists, curves and a high-speed drop; Little Dipper, a fun log flume ride for the younger set; and Crocodile Run, in which riders get to navigate the waters while keeping an eye out for the "crocs."
Bayville Adventure Park — Bayville
8 Bayville Avenue
Who ever would imagine the tiny North Shore community of Bayville would host one of the Island's most popular amusement attractions? Bayville Adventure Park is across the street from the Long Island Sound. In addition to its pirate-themed mini-golf course, rock climbing walls, arcade, and funhouse, the park features a bumper-boat safari course, and a spirited water balloon attraction. In the autumn, the park transitions into Bayville Scream Park.
Boomer's Family Fun Center — Medford
The bumper boats might not be the primary attraction at this multi-themed family center in the center of the Island. But after a few runs on the go-kart course and roller coaster, and some swings in the batting cage, who can resist cooling off on the bumper car-like water track? Note: The demolition-derby theme requires kids to be at least 44 inches tall.
Cantiague Park — Hicksville
480 West John Street
Hugely popular with Nassau County residents, the outdoor swimming facility at Cantiague Park features everything the serious and not-so-serious swimmer needs, including an Olympic-sized pool and a diving pool, a training pool and kiddie pool for little ones, and two water slides. What more does a family need?
North Woodmere Park — Valley Stream
750 Hungry Harbor Road
Another favorite spot to cool off in the summer, North Woodmere Park has not one, not two, but three water features for young swimmers: a wading pool, training pool, and an interactive water-play area. For the rest of the family, there is an Olympic-sized pool, a diving pool, and a huge water slide.
The Tunnel of Terror at Splish Splash.
Splish Splash — Calverton
2549 Splish Splash Drive
When most Long Islanders think water park they immediately think Splish Splash. And, why not? This 95-acre park has enough water-themed rides, slides, and attractions to keep an entire family happily saturated. Thrill-seekers can head to the Cliff Diver, an extreme body slide that drops guests eight stories in just three seconds and the Abyss, which takes guests on a twisting-turning adventure. A family of four can take a ride on Bootleggers Run, and, of course, there's a large kiddie area just for little ones.
Town of Brookhaven Pools — Centereach and Holtsville
286 Hawkins Road, Centereach
249 Buckley Road, Holtsville
Families have their choice of two public pools in the Town of Brookhaven. The main pool in Centereach has a 16-foot slide and a spray pad with water features for younger children, while the Holtsville complex includes the main pool, dive tank and a kiddie pool.
Wantagh Park — Wantagh
1 King Road
The whole family will have fun spending the day at this swimming complex, which has water amenities to suit all preferences and abilities, including an Olympic-sized pool, diving pool, kiddie pool, and training pool. There are two 30-foot water slides plus an interactive water-play area.
