The demonstration, led by the group ‘Canary Islands have a limit’, drew attention to growing concerns over rising housing costs, pressure on infrastructure, and environmental harm caused by the high number of visitors.
Organisers say the current tourism model benefits few locals despite welcoming nearly 18 million tourists in 2024.
Protesters are urging authorities to introduce an eco-tax, suspend new tourist accommodation permits, and regulate property purchases by non-residents.
It follows an earlier mass protest in April, signalling deepening frustration among island residents over the long-term viability of tourism-led development.
