Portuguese beaches are clean, safe and most have nice white sand. There is a national safety system in place that uses flags to communicate conditions:

  • Red flags = NO Swimming
  • Yellow flags = Use Caution
  • Green flags = All Clear for Swimming

Portugal: list of Blue Flag beaches and marinas - www.Bandeira Azul - This voluntary organization works towards sustainable development at beaches and marinas worldwide by awarding Blue Flags when strict criteria for safety,  water quality, and environmental education and management are met.
