Kids will fall for the Tahiti Tree House with tipping bucket and Pirate’s Pool & Lagoon featuring cannons, slides, and volcanoes at Water Country in Portsmouth, New Hampshire. The littlest ones will go gaga splashing around Bubble Bay’s geysers and climbing Ollie Octopus in a shallow, zero-entry pool. The New England water park’s 26 acres also include bigger thrills for bigger kids, such as a whirlpool, activity pool, and 700,000-gallon wave pool. The lazy river boasts caves, waterfalls, and fountains. A whitewater rafting group tube slide; a two-lane, head-first racing slide; and an extreme 58-foot body slide are also favorites. Water Country opens full-time on June 15. For more water park ideas, check out our New England Water Parks Guide.
