An "isle" is a small island, often found in rivers, lakes, or coastal areas. It can be a natural landform or a man-made structure. Isles are typically characterized by their isolation from larger land masses, making them unique ecosystems that can host various plants and animals. Isles can vary in size and shape, ranging from tiny patches of land to larger, more developed areas. They are often popular destinations for recreation and tourism, attracting visitors who enjoy activities like hiking, fishing, and birdwatching. Some famous isles include Ellis Island and Treasure Island.
