🏆 Family Action Verdict

Best for families with kids aged 4 and up who meet height requirements—42" for the tidal river with a complimentary life jacket, 48" for the tower tube slides. The Rain Fortress has a lower 40" threshold for its tallest slides, making it accessible to younger kids.

ℹ️ What to Know Before You Go

💡Arrive early on hot summer days—guest volume can trigger wait times at the park entrance

⏰Complimentary life jackets are available for riders under 42" on the tidal river

🎟️Check the Canobie Lake Park website for the seasonal operating calendar before planning a visit

🚗Proper swimwear is required for all Castaway Island attractions—no cutoffs or street clothes

Overview

Castaway Island is the water park section of Canobie Lake Park in Salem, NH. Its centerpiece Tidal River is one of only a few tidal rivers built in the US—a zero-entry wave pool feeds into a current-driven river that pushes riders past themed scenery. Slide Island's 62-foot tower offers three tube slides: an open-top sun ride, a fully enclosed dark tunnel, and a variable-width whip slide.
