Castaway Island at Canobie Lake

Castaway Island at Canobie Lake brings pirate-themed water fun to New Hampshire's classic amusement park. This outdoor water park sits adjacent to the main Canobie Lake Park, making it easy to hop between dry rides and water attractions during your visit. The pirate theming runs throughout, from treasure chest decorations to nautical playground structures that make kids feel like they're exploring a real shipwreck. The centerpiece is a multi-level water playground complete with tipping buckets, smaller slides perfect for younger kids, and interactive water features. You'll find a good selection of body slides and tube slides that provide thrills without being too intense for families. The lazy river winds around the park and gives you a chance to float and relax between more active attractions. For the littlest pirates, there's a dedicated splash area with mini slides and gentle fountains. What sets Castaway Island apart is its integration with Canobie Lake Park. You can buy combination tickets and move freely between both parks, which is perfect for families with mixed interests. Some want roller coasters, others want to cool off in the water, and here you can do both. The park gets busy on hot summer weekends, so arrive early if you want to claim chairs near the action. The food options are typical amusement park fare, but you can also grab something from the main park if you want more variety. Bring reef-safe sunscreen since you'll be in the sun most of the day, and water shoes help on the hot concrete. The park operates seasonally from late spring through early fall, and it's really designed with families in mind. Teens might want more extreme slides, but for families with elementary-age kids, the scale feels just right. The combination of manageable crowds, reasonable prices, and the bonus of having a full amusement park next door makes this a solid choice for a New Hampshire summer day.
