Locals in Majorca have called for residents to storm the island's beaches in protest against mass tourism.
Around 10,000 people marched through the capital, Palma, demanding limits on the number of visitors last weekend.
They voiced concerns over Airbnb-style rentals undermining affordable housing, scarce water supplies being used to fill swimming pools and roads congested with holidaymakers' cars.
The protest group Mallorca Platja Tour took to social media, posting on X: “We urge residents to fill the beaches of Mallorca as a demonstration against overcrowding.”
The group, which announced plans for a mobilisation in the middle of next month, added: "We invite all residents who live near the beaches to go there to reclaim our beaches and enjoy them as before."
Describing itself as "a civic, peaceful, and family response" to mass tourism, the group added: "We will simply go swimming to show that the beaches belong to everyone, they are a public asset, and we are not going to resign ourselves."
Tourism accounts for 12 to 13 per cent of GDP in Spain, but there is growing opposition to the industry's impact on the lives of locals.
Thousands of residents in the Canary Islands protested at the end of last month against the surge of tourist flats and overcrowding in many destinations. They called for measures to boost residents' access to housing.
It comes as holiday operator TUI announced that the Balearic Islands have "reached capacity" and urged holidaymakers to consider other destinations for their sunny getaways, following recent anti-tourism protests across Spain.
The CEO of TUI, Sebastian Ebel, 61, stated that the company had reached its 'capacity limits' in the Balearics and is now looking to other Mediterranean destinations for growth.
According to the Majorca Daily Bulletin, less crowded destinations include Egypt and Turkey, with Algeria also being a potential option.
The travel company acknowledged that the Spanish archipelago cannot host an increasing number of holidaymakers.
TUI is already expecting to bring around two million tourists to the Balearics this summer, five per cent more than last year.
Despite the pause on the Balearics, the TUI boss revealed he had recently discussed the possibility of opening up Algeria for beach holidays.

Between 2010 and 2018 tourist accommodation on the islands increased by 80 per cent. There has been a 30 per cent decline in ordinary rental properties and a 12 per cent increase in price.
In the centre of Madrid, almost a tenth of properties are dedicated to tourism. In the centre of Malaga, the proportion is a quarter.
An editorial this week in El Pais, the daily newspaper, urged that "the different authorities must now seek joint solutions in accordance with the urgency of the problem".
Movements against mass tourism on the island are gaining influence and threatening further action.
Jaime Martínez, the mayor of Palma, announced on Monday his intention to limit the influx of tourists by restricting cruise ships, rental cars and setting quotas for group visits.
On Tuesday, the regional government of the Balearic Islands issued a decree granting local authorities the power to act against illegal tourist accommodation, enabling tourism inspectors to seal off such properties.
