Hi
What I can say with certainty is that since the beds started to appear in 2014 the beach started to get cleaner.
My first visit to Arrillas in 2010 found a very untidy beach.
My second visit in 2011 and working with Clive (an English guy) who was chairman of the Keep Arillas Tidy Committee, we cleared 25 sacks of rubbish, 4 fridge compressors and a moped frame over a two week period.
In 2012 the beach was very tidy from day one. In 2013 I cleared 14 sacks of rubbish in two weeks.
As said, in 2014 the beds started and the beach has since been tidier.
I posted beach clean reviews on this forum in my early years of visiting and received lots of support.
Perhaps the majority of bed users keep the beach tidy rather the minority of non bed users making a mess?
Christina the current bed operator certainly does her bit.
9. 30 and off to the beach.
