Looking for naturist places

Hello,
I am a vlogger on Youtube about unusual destinations on my channel GROSvoyage @isidorevivant https://www.youtube.com/channel/UCidrtzFkfM8y5qcHJF29QNg
and I will be filming in Lithuania between August 12 and 17.
I would like to do a video sequence on socila meeting places for naturists.
Can you advise me some (apart from nude beaches) ?
Thanks for your help.
