Last week, two beaches in Los Cristianos were targeted by protesters with sunbeds at Los Vistas and El Camison vandalised by a number of unknown individuals.
According to Arona City Council, it was a "coordinated attack", with the sunbeds sprayed with anti-tourism graffiti.
One slogan was "Canarias se defiende", which translates to "the Canary Islands defend themselves".
Another was "Canarias no se vende", which means "the Canary Islands are not for sale".
In a statement, Mayor Fatima Lemes said: "We are against all types of vandalism and the lack of civility of some people who attack Arona's heritage, which causes serious harm to both residents and visitors."
She also appealed for locals to help identify those responsible, reminding them that they will be punished by law.
Earlier this year, tens of thousands of protestors marched as they called for limits on uncontrolled development, which they say is damaging not only the environment, but also people's way of life.
Videos on social media showed people slashing the sunbeds with knives, with Las Vistas seeing 100 loungers defaced, while El Camison had 136 damaged.
A nearby shopping centre was also targeted with graffiti as part of the protest, while the cost of damages are thought to be around €5,000, according to the Canarian Weekly newspaper.
Other protests this year include people going on hunger strike to try and stop the construction of a new resort.
Activist Daniel Cabrera has told the Standard newspaper: “We want tourism. What we do not want is over-exploitation and garbage tourism that does not benefit the local economy.”
