While the signs warn holidaymakers to stay away - messages in Catalan underneath make clear there is no danger.

One sign has the words "Beach Closed" in English, with a no swimming sign - but just underneath a message tells Catalan speakers the opposite, "Platja Oberta" - or "Beach Open".

Another poster claims it is a near three-hour walk to the beach when it is a few metres away.

Under an image of a swimmer surrounded by jellyfish, one sign reads, "Beach Open. Not to jelly fish or foreigners".

Another sign warns of the "danger" of " falling rocks" and "landslides".

Anti-capitalist group Manacor Caterva are behind the unofficial signs, which it says are "charged with humour".

In a post on X, formerly known as Twitter, the group wrote: "If you want to use the images and print posters you just have to ask us and we will send them to you in good quality. Let's continue the fight!"

The protest group criticised the "overcrowding" of beaches and "mass tourism" in a news release to local media.

It has put up the signs in Cala Morlanda, Es Calo, Cala Petita, Porto Cristo, Cala Murta, Cala Magraner and Cala Bota.
