We just got home from a week at Wekiwa Springs State Park, FL and had a Wonderful trip.
The sites are all generously sized and well spaced, most of the sites have "full" hookups which include sewer.
There is a huge Natural fresh water Spring where you can go swimming to cool off. The park also has lots of wildlife and great trails for hiking or biking. We spotted a deer and several wild turkeys as well as a split-tailed hawk.
If you are looking for a great camping experience in the Central Florida/Orlando area we highly recommend this State Park.
Reservations can be made through Reserve America .com.
Beginning in August 2016 the park will be upgrading the electric system to 50 amp service, consequently, reservations will not be available through Reserve America until completion. However, the park Rangers told me they would keep the camping sites open and available on a First Come, First Served basis during construction.
