Along the old N-340 coast road from Nerja to Almuñécar there are a number of secluded, and undeveloped little coves and sandy beaches. Ideal if you want to get away from the crowds.
This one is Las Alberquillas beach. It is 400 metres long, 20 metres wide and there no facilities whatsoever. It is just past km 299 and you park at the top then walk down to the beach.
