Discover more about Mount Karthala

Mount Karthala, or Karthola, is a majestic and active shield volcano that forms the heart of Grande Comore, the largest island in the Comoros archipelago. Rising to 2,361 meters (7,746 feet), it is the highest point in the nation and a dominant feature of the island's landscape. Its broad, gentle slopes are covered in moist evergreen forests up to 1,800 meters, giving way to stunted trees and heathland at higher elevations.Karthala is one of the world's most active volcanoes, with over 20 recorded eruptions since the 19th century. These eruptions have shaped its massive 3 km by 4 km summit caldera, one of the largest active volcanic craters in the world. While eruptions are frequent, the island has largely been spared major destruction, though past events have caused evacuations and ashfall.Hiking Mount Karthala is a challenging but unforgettable experience. Treks typically start from villages near Moroni and can take 6-10 hours to reach the summit, passing through diverse ecosystems from tropical rainforests to volcanic rock. The best time to hike is during the dry season, from April to November. Reaching the summit rewards hikers with breathtaking views of the vast crater and the surrounding Indian Ocean. The mountain is also home to unique flora and fauna, including endemic bird species like the Karthala Scops Owl.Mount Karthala National Park, established in 2010, protects 262.14 km2 of the mountain's diverse environment. However, the mountain's forests face threats from logging and agricultural expansion, highlighting the need for continued conservation efforts.
