Secure RV parking Anhinga Trail and Shark Valley (Florida)

Mornings would certainly be better than the afternoons at that time of year.

As to the security of the parking areas, I think it's fine. Just lock your doors and don't leave valuables out where they can be seen through the windows.

We just made a trip to that area a few weeks ago, and I posted a trip report in the Truck Camper section of this forum if you're interested.
