Carowinds’ waterpark, Carolina Harbor, typically opens for the summer season on Memorial Day weekend, with the 2025 opening day listed as Saturday, May 24, 2025.

Quick Scoop

  • For 2025, Carolina Harbor’s official event page and press materials state that the waterpark opens on Saturday, May 24 , kicking off the summer “Carolina Harbor Opening Day” event.
  • Hours on that event listing are 11 AM – 6 PM for opening day, though hours can vary on later dates, so checking the park’s calendar before you go is important.
  • Entry to Carolina Harbor is included with regular Carowinds admission, so you don’t need a separate waterpark ticket.

If you’re planning for 2026 or beyond, the main Carowinds ride park is set to open its season in mid‑March 2026, but specific waterpark dates for that year have not yet been published in the same detail as 2025; expect a similar late‑May/Memorial Day‑weekend pattern and confirm closer to your visit on the official site or event calendar.
