A "loch" is a Scottish term for a lake or a sea inlet. It is commonly found in Scotland and can vary in size and depth. Lochs are often characterized by their scenic beauty, surrounded by hills and forests, making them popular destinations for outdoor activities like hiking and fishing. There are two main types of lochs: freshwater and saltwater. Freshwater lochs, such as Loch Ness, are known for their unique ecosystems and sometimes mythical creatures. Saltwater lochs, like Loch Fyne, serve as important harbors and support local fishing industries.
