Charco Azul is a creatively designed combination of moulded concrete with natural volcanic rocks. The effect is stunning: a series of natural-looking saltwater pools with sunbathing platforms and a walkway between them. Charco Azul is located 6km northwest of San Andrés on the LP-104 highway. Alternatively, bus 104 from Los Sauces passes by here three times daily (€1.50, 10 minutes).
