The following is a list of many favorites within a few hours of Orlando, but my personal best is pretty close by at Blue Spring State Park. Claiming the title of the biggest spring found on the St. John’s River, this stop on the list is manatee heaven from the middle of November until the end of March. Any in-water activity is put to a halt during this time, but once the park fully reopens, attendees can enjoy some snorkeling, boating, fishing, tubing and, if you’re certified, scuba diving.
