The Lake District, England’s largest national park, is home to the most famous, and biggest, lakes in the country. While generally referred to as “lakes,” many of them are officially classed as “meres”, “waters” or even reservoirs. These bodies of water vary in size, depth, and character, from the vast waters of Windermere to the remote and dramatic Wast Water. Each lake has its own unique charm, attracting visitors for boating, walking, wildlife spotting, and simply enjoying the scenery.
