I'm pretty sure they charged me 60 or 65 euros as a newbie tourist visiting on Sunday. Perhaps the special is new or the web site is dated or I'm rememembing incorrectly, but I don't think so. I do know for certain that the receptionist told me they had 8 girls working that Sunday when there were only 5, a number I confirmed when I spoke with the girls inside. You may want to call to check the price in advance just in case.
Despite the price hiccup and much smaller facilities than most, I had a good time here and would return in the future (after calling to confirm entrance fee).
If you come here by navigation system, something I very highly recommend (see my driving suggestions at https://www.clubhombre.com/discus/messages/1360/52952.html) you may approach from the west. Once you've reached Franziusstrasse, continue until you reach the T-intersection where it meets Intzestrasse and Beach will be right there at the base of the T.

This FKK is small with an unusual layout I can't reconstruct from memory. If you're looking for a large comfortable FKK to lounge about in or one with a vast selection of girls, The Beach may not be for you. But if you want something small, cozy, and different with girls you can see in advance and have a photo memento of, then The Beach stands out. (Photo memento from website below, like most FKKs photography is not allowed inside)
Many if not all of the girls working here can be seen on the Starlight Ladies website: http://www.starlight-ladies.de
The following four girls were there that Sunday: Anita, Justin, Carolina, Nathalie.
The fifth may have been Victoria, but I'm not sure because she looked bad in person, or at least that night.
I had an excellent session with Anita and could easily return for Maria, Nathalie, and maybe Justin.
I'd recommend Oase, World, Palace, and Atlantis (now closed again) before The Beach, but if you don't mind the negatives or like the positives I described, I'd so go ahead and make a visit.
