We just got back from Orlando.
We always hit one of the springs that the Manatees winter in, super cool. Silver Springs is fun if you guys want to do a glass bottom boat tour.
A bit of a drive but Crystal River you can actually get in the water with them.
Blue Springs is near but very crowded.
Also, no manatees here but renting a canoe and paddling down the Wekiva River is really fun. Always see gators and I took my fishing pole this last time and hooked into a couple bass and sunfish.
If it’s warm out Wekiwa Springs is a fun swim too. Crystal clear water and you can swim right over the actual spring.
