Spain doesn’t have any specific federal bans on getting naked on its beaches, though some cities may designate certain areas where it’s prohibited. If you want to be sure, head to one of the 300 official nude beaches.
Smoking is banned in all enclosed public places, including on public transportation. You are also not allowed to smoke outside healthcare facilities, schools and playgrounds. Hotels may have smoking rooms available if requested.
