Cayes are small, low-lying islands or reefs, often found in tropical regions. They are typically formed from coral and are surrounded by shallow waters. The term "caye" is commonly used in places like the Caribbean, where they can serve as beautiful vacation spots and habitats for various marine life. Many cayes are part of larger ecosystems, such as coral reefs, which provide essential services like protecting coastlines and supporting biodiversity. Popular examples of cayes include Ambergris Caye and Caye Caulker in Belize, known for their stunning beaches and vibrant underwater activities.
