5 /5 Robert McClellan: If you have a rainy weekend and are looking for something to do, the Calusa Nature Center and Planetarium is an inexpensive and enjoyable visit where the kids might even learn a little something. The newly renovated Planetarium has super comfortable seating and the new projection system is truly remarkable. In between Planetarium shows they offer animal experience shows where the kids can get up close and personal with anything from a turtle, snake, or even a baby gator. The rustic trails are short but can provide some quiet time in between programs. Pretty easy to spend the day.. they dont offer any food, but there is a large covered area with plenty of tables for sack lunches or snack time. Always enjoyable.
