Blue Spring State Park is a state park located west of Orange City, Florida in the United States. The park is a popular tourist destination; available activities include canoeing, SCUBA diving, kayaking, fishing, camping, hiking, wildlife watching, and swimming. The spring is the largest on the St. Johns River and with a relatively warm temperature of 73 °F (23 °C), the spring attracts many Florida manatees during the winter months. 102 million US gallons (390,000 m) of water flow out of Blue Spring into the St. Johns River every day.[1]
