Playalinda beach on the space coast, near Titusville and next to the launch pads. Last parking lot is clothing optional. Really clean and natural beach. Also great for watching rocket launches, if they keep the beach open for it.
(The structures in the distance are rocket launch towers, it’s legitimately the closest you can get.)
Yes, however the nude section is the furthest parking lot, which is 4 miles north of where this was taken. Still a spectacle and much closer than most people will see a rocket launch, but if you came to see a launch then you probably want to be as close as possible
