Cuban topography is characterized by a mix of flat plains, rolling hills, and mountain ranges. The island's highest point is Pico Turquino, located in the Sierra Maestra mountains, which rise to about 2,005 meters (6,578 feet). The central region features fertile valleys, while the northern and southern coasts are lined with beautiful beaches and coral reefs. The western part of Cuba is home to the Viñales Valley, known for its unique limestone formations called mogotes. The eastern region includes the Sierra de los Órganos and the Sierra del Cristal, which contribute to the island's diverse ecosystems and rich biodiversity.
