The Lea Valley Walk is one of the finest and most varied walking routes around the capital, and an excellent way to get out of (and into) London. It offers 50 miles of traffic-free walking, tracing the route of the River Lea from its source at Leagrave near Luton to where it meets the Thames in east London. As the route follows the river it undergoes a fascinating metamorphosis from urban trail to rural pathway. So, whether you choose to walk for health, fresh air or views of wildlife and countryside, to visit friends, to explore heritage attractions, to escape or simply to explore your surroundings, the Lea Valley Walk offers it all. The Prince of Wales, making his maiden speech in the House of Lords in 1974, described the Lee Valley Park as 'a classic example of what could be done with derelict land if impetus and determination was there'. A quarter of a century later the Lea Valley, once London's market garden, is again recognised as a rich green lung running down the east side of the capital. This is a walk that can be enjoyed by everybody from the keen long-distance walker to those with young children or those new to taking exercise. Thanks to the many railway stations alongside the Park, between Ware and London, the Walk can be reached easily. Some of the sections are very short. Indeed, these stretches often contain much heritage and countryside to enjoy - such as the one mile between Cheshunt and Waltham Abbey.
