Some of the most famous lochs include Loch Ness, renowned for its mythical creature, and Loch Lomond, celebrated for its picturesque landscapes. Many lochs are surrounded by mountains and forests, making them popular destinations for outdoor activities such as hiking, fishing, and boating. The diverse ecosystems within these lochs support various wildlife, including birds and fish, contributing to Scotland's rich biodiversity.
