About
The town council's Education department runs Los Días sin Cole, an open-schools program for parents who work when schools are closed. On holidays and teacher days, a public primary school stays open from early morning to mid-afternoon, with crafts, stories, games, sports and the odd outing built around a theme. Families book single days or a whole break, with lunch optional.
