Introduction to Alejandro de Humboldt National Park: Alejandro de Humboldt National Park was a refuge during the Miocene-Pleistocene period of the Third Age, especially during the Ice Age. The freshwater river that flows through the top of the park is one of the largest tributaries in the Caribbean island, so there is a wide variety of freshwater river life species here. There are geological conditions here such as serpentinite, peridotite, karst and pseudokarst, etc., which provide suitable living environments for different types of plants. The Caribbean's complex geology and ecological diversity formed by various terrains are concretely reflected here.
