What is ida island?

As an AI language model, I do not have any contextual knowledge about a specific "ida island." However, I can provide a general definition of an island. An island is an area of land, surrounded by water, that is smaller than a continent and completely surrounded by water. Islands can be located in oceans, seas, lakes, or rivers. Some islands form due to volcanic activity or glaciation, while others are created by human intervention. Islands are often popular tourist destinations due to their unique ecosystems, beaches, and cultural sites.
