Lichtbund Karlsruhe

What a fantastic naturist campsite. Everything you could possibly want is there: a swimming pool, tennis courts, archery ranges, and pétanque courts. There's an indoor area where you can buy drinks and ice cream. The restrooms have been completely renovated. The managers are super friendly. Email in advance to let them know you're coming, and they'll give you a phone number to call when you arrive at the gate. I say absolutely fantastic. One minor point: you can hear the autobahn.
