However, the joke is reserved for locals, or those who can read the part of the sign written in Catalan.
It’s this part of the sign that reveals the messages are fake.
“Open beach, neither sea urchins nor jellyfish,” reads one sign, right below a symbol of a swimmer being stung by jellyfish and the words “Beware of dangerous jellyfish”.
On another sign that reads “Caution falling rocks”, with a symbol for rock fall, the Catalan wording translates as “the danger is not of a landslide but of overcrowding”.
Anti-capitalist group Caterva is behind the signs, posting photos on its Twitter account on August 12.
“We have carried out a denunciation action against the #tourist overcrowding in the coves of #Manacor,” read a translation of the post.
The group said it had put up the posters at beaches between Cala Morlanda and Cala Bota “with a bit of humour”.
It said overcrowded beaches were an expression of how capitalism used tourism to get as much value as possible out of destinations or local workers.
Caterva isn’t the first group to push back against the surge of summer tourists in Europe.
In other instances, restaurants have added charges for simple requests such as an extra spoon and locals have rented beach chairs for $128 an hour.
