The Coatepeque Caldera is a majestic volcanic feature located in the Santa Ana Department, housing one of the most beautiful crater lakes in Central America. The caldera was formed by a series of massive rhyolitic eruptions between 72,000 and 57,000 years ago, leading to the collapse of the volcanic edifice and the creation of the current basin. Lake Coatepeque sits at an elevation of 745 meters above sea level and covers an area of approximately 26 square kilometers. A fascinating natural phenomenon occurs periodically when the lake's waters turn an intense turquoise color, attributed to algae blooms or hydrothermal activity. Within the caldera, several lava domes are present, including Teopán Island, which was once a sacred site for the Mayan civilization. Today, the area is a major tourist destination renowned for water sports and upscale developments, while also being under environmental protection to safeguard its water quality.
