After the eruptions in 1730, the crater of the volcano has been flooded and so the green lagoon was formed. Even today the lagoon is connected to the sea by underground tunnels and is separated from the sea by a sandy beach; its green color comes from the presence of a large number of plant organisms in suspension. The green color of the lagoon is in great contrast with the deep blue of the ocean and the entire landscape, with the volcanic rocks in the background, providing a very unique sight. El Golfo has been declared a nature reserve and so now it's forbidden to swim in the lake, which is why it's surrounded by a wooden fence. From the parking lot, there's a dirt pathway that takes you to the viewpoint from where you can admire the lake and take the best photos. Since Lago Verde is situated on the west side of the island, it is a great place to come and watch the sunset, especially because the area becomes very quiet and the bus tours are gone, so you're likely to be pretty much alone.
