A cape is a geographical feature that usually refers to a headland of large size extending into a body of water, often marking a change in coastline direction. Capes can be significant for maritime navigation and are often well-known for their natural beauty. For example, the Cape of Good Hope is a notable cape that serves as a landmark at the southern tip of Africa. In general, capes can be crucial for understanding coastal ecosystems and for their historical significance in maritime exploration and trade routes.
