Tucked into the hills of Southern Indiana, Big Splash Adventure was built around one simple idea: family time should never depend on the forecast. Under our roof you'll find 40,000 square feet of slides, rivers, lagoons and pools, warm and ready whether it's July or January. Attached to the park is our 153-room hotel, so the fun is only an elevator ride away. From the first plunge down Pirate's Plunder to the last lap around the Lost River, we're here to help your family make memories worth talking about on the drive home.
