After her 100 yard walkabout down Castle Hill, Her Majesty officially opened The Queen's Walkway - a 6.3 km walking trail which connects 63 points of significance in the town of Windsor. It was designed by The Outdoor Trust to symbolically recognize the moment that The Queen became Britain's longest reigning monarch after more than 63 years on the throne.
