This weekend, thousands of Balearic Islanders protested against overcrowding and mass tourism by taking to the streets.

On Saturday, protesters marched through the Spanish island provinces of Menorca and Mallorca in an effort to voice their opposition to the "massification" of tourists.

Despite the fact that, according to figures from industry organization Exceltur, tourism contributes roughly 45% of the Balearic Islands' GDP, protestors claim vacation rentals are driving away residents.

Carme Reines, from a collective which organised the protest in Palma de Mallorca, said: "We want the authorities to stop people who have not lived here more than five years from buying properties and to put more controls on holiday accommodation."

Javier Carbonell, a real estate agent in Mallorca, added: "We want less mass tourism and more sustainable tourism."

A Spanish National police spokesperson said around 10,000 people took part in the protest in Mallorca, while a few hundred marched in Menorca.

The Balearic Group of Ornithology and Nature Protection of Menorca (GOB Menorca) said on its website that it was protesting "the massification of tourism, the problem of access to housing, water management and the economic diversification of the island".

In a post on social media, the group added the demonstrators turned Menorca's Plaza de la Biosfera into a mock beachfront by turning up with deckchairs, towels and sunglasses.

It's the latest in a string of protests on Spain's islands against mass tourism.

The Menorca and Mallorca protests came at the same time as an anti-tourist march in Barcelona, and just a day after around 1,000 demonstrated in Ibiza.
