Crystal clear waters with a year-round temperature of 72 degrees attracts thousands of visitors each year to Blue Spring State Park, just west of Orange City in Volusia County. The spring is best known for attracting manatees during the colder months, as they seek warmer waters than the St. Johns River can offer. When the river warms up and the manatees leave the spring, it is open for swimming, canoeing and kayaking. The spring also is popular with SCUBA divers and snorkelers. This is truly a beautiful spot and worth the short drive. One of Florida's natural treasures.
