The main reason this region is considered a sex tourism destination are the striptease clubs in Valencia. They are not quite the Central European mega brothels or FKK clubs but close enough and have a wide variety of beautiful local and foreign chicas.
Sala Maxx (https://newsalamaxx.com/) at Camí del Port, 300 is a local icon. It comprises a brothel, a titty bar, and a respectable night club on its own. Club Paris (http://www.clubparis.es/) at Carretera V23 is a similar place, but with a pool area and delicious sandwiches. And last but not least: you got Burbujas (https://burbujasnightclub.es/) at Carrer d'Astúries, 42, an erotic nightclub with charming colonial interiors.
