One cannot cruise for very long on the Andalucían coast without encountering the string of yacht marinas and sport fishing harbours financed, built and run by the Agencia Pública de Puertos de Andalucía.
The APPA website developed in recent years is at: https://www.puertosdeandalucia.es/en/ and contains a wealth of useful information for yachtsmen. One of the most exciting developments has been provision of current bathymetric charts for the entrances to marinas and harbours to help with navigation in areas where shifting sands and bars are a worry. On the web page at https://www.puertosdeandalucia.es/en/documentation-en/batimetrias the Batimetría del Río Piedras (Febrero 2018), for example, showing depths and buoy positions can be downloaded for the entrance to the Rio de las Piédras (El Rompido).
