Yes, you can absolutely walk on the Long Walk in Windsor Great Park, and it is one of the most iconic strolls in the United Kingdom. This straight, tree-lined avenue stretches for approximately 2.6 miles (4.2 kilometers) from George IV Gateway at Windsor Castle to the Copper Horse statue (depicting King George III) atop Snow Hill. The path is paved and generally accessible, providing a majestic, unobstructed view of the castle's silhouette. While the castle itself is a private royal residence and requires a ticket for entry, the Long Walk is public land and is free to access. It is a favorite spot for locals and tourists for walking, jogging, and photography. However, it is important to note that cycling is generally prohibited on the main path of the Long Walk to preserve the experience for pedestrians. Also, because the walk is quite long and offers very little shade or seating, visitors are advised to bring water and wear comfortable shoes. Standing at the Copper Horse and looking back toward the Castle provides one of the most famous vistas in British history.
