Get ready for a truly surreal sight at Charco Verde, a stunning emerald-green lagoon nestled within a volcanic crater right by the sea. The contrast of the vibrant green water against the black sand beach and reddish cliffs is something you won't forget. It’s an easy and quick visit; a short, five-minute walk from the free car park leads you straight to a viewpoint for the best panoramic photos. For the most dramatic colors, try to visit at sunset.
