Ometepe is a fascinating island located in Lake Nicaragua, boasting two majestic volcanoes, Volcán Concepción and Volcán Maderas, which rise out of the lake. With an area of 276 square kilometers, Ometepe is situated in the Rivas Department of the Republic of Nicaragua. The name 'Ometepetl' comes from the Nahuatl words 'ome' (two) and 'tepetl' (mountain), which means 'two mountains'. Ometepe is the largest island in Lake Nicaragua. The two volcanoes, Volcán Concepción and Volcán Maderas, are connected by a narrow isthmus, creating an island shaped like an hourglass, dumbbell, or peanut. The island spans an impressive 31 kilometers in length and 5 to 10 kilometers in width. Its diverse economy relies on a combination of livestock, agriculture, and tourism, which all contribute to the island's prosperity. Ometepe Island is home to significant populations of the White-Faced Capuchin Monkey, also known as the White-Headed Capuchin, and to significant populations of the Mantled Howler Monkey. Exciting efforts are underway to study and protect these amazing animals. The Ometepe Biological Field School, located on the Maderas side of the island, attracts enthusiastic students and scientists from around the world who come to study the unique and fascinating flora and fauna of the region. The lake around Ometepe is home to many species of aquatic animals, most notably the Nicaragua Shark, which until recently was believed to be a unique species of freshwater shark, but has since been proven to be connected to marine populations. Furthermore, there are small populations of Spider Monkeys living on very small islands in Lake Nicaragua.
