Desert islands are uninhabited land masses surrounded by water, often characterized by sandy beaches, palm trees, and limited vegetation. They can be found in oceans, seas, and even large lakes. These islands are typically small and remote, making them difficult to access. Many desert islands are formed through volcanic activity or erosion. They can serve as important habitats for various wildlife, including birds and marine life. Some famous desert islands include Easter Island and Castaway Cay, which attract tourists seeking adventure or solitude.
