"There's one just the other side of Palafrugel which has a beautiful stretch of beach. Its through Palafrugel from Girona and a left turn. Not Callela, but something similar. If I remember the name I'll post it."
Could it have been Tamariu? Excellent campsite. Shaded. Short walk into resort so no need to drive. Lovely bay with a couple of laid back bars. Great place.
Can highly recommend https://www.campinglasiesta.com in Calella de Palafrugell.
Been there three times.
