All the cold winter days of January mean the manatees flock to the warmer waters of Blue Springs. On the day I went there were over 300 manatees in the springs. There was also a 30+ minute wait time just to get in the park to see them! It was well worth the wait as the manatees were actively playing in the water, and just beneath the docks, right under your feet. You could not ask for better viewing.
