Just outside of Jackson, Mississippi, this 10-year-old water park reopened in 2011 after receiving a major facelift, making it worth the drive. Older kids can get turned around on the Backsplash while tots squeal and giggle in Lil' Squirt's Hollow. Parents will enjoy relaxing in cabanas by the white sands of Clearwater Key. Admission: $35/adults, $25/under 48", Free/3 and under. Season pass: $90/adults, $75/ages 4-11 (plus tax and fees). Group rates and birthday packages available.
