An unconventional and fun way to get to know the city. This is a tour where history meets sexy, but not only that: unlike other free walking tours, your guide puts emphasis on interaction, so you're free to express ideas and ask questions, and (maybe) even question beliefs. All in all, it's an erotico-philosophical-educational two-hour tour for any open-minded and curious visitors looking to explore parts of Barcelona in a new way.
The tour is free/donation-based, though you will pay €5 entry fee into the Erotic Museum (regular price €12), and that includes a glass of cava in the museum's garden. Book your spot in advance. Tour in English.
