The Costa de la Luz in the Huelva Province runs from the Guadiana River to the Guadalquivir River in the east. The months of July and August are the peak holiday season and resorts are packed. If you are looking for a lively vacation, come during this time and make sure to book your Self catering Costa de la Luz or Huelva Spain holiday rentals in advance. Fortunately, even during this time, you can find some secluded spots on the beach. During other months, Costa de la Luz in Huelva dies down drastically and transforms into a very quiet and empty area.
