The topography of Belize is characterized by rugged terrain with steep hills and valleys, deep and narrow gorges, and numerous stream channels.
The country is dominated by the Maya Mountains, which run from north to south and have several peaks over 3,000 feet.
To the east of the Maya Mountains lies a narrow coastal plain, which is about 15 miles wide and includes many small cayes and islands.
Lastly, the western part of Belize is marked by a series of low-lying, swampy areas, which are referred to locally as savannas.
The highest point in Belize is Doyle's Delight, which stands at 3,688 feet. It is located in the Maya Mountains near the Guatemalan border.
The lowest point in Belize is the Caribbean Sea, which has an elevation of 0 feet.
Belize’s topography is unique compared to other Central American countries because of the presence of the Maya Mountains. Its coastal lowlands are less extensive than neighboring countries.
