Thames Path : British Walking Guide: Thames Head to London - Includes 89 Large-Scale Walking Maps (1:20,000) and Guides to 99 Towns and Villages - Planning, Places to Stay, Places to Eat

Barrier in London. Officially 184 miles (294km) in length (although the actual distance you walk will depend on a number of decisions you make en route), the path meanders, accompanied by its watery muse, through pristine and tranquil countryside, past historic sites and buildings, via pub, lock, weir, and the occasional scattering of waterfowl, to a city, once the fulcrum of an empire, and now the heart of modern day England. The river, responsible for the metropolis' very being, tells tales, inspires artists, accommodates swans, geese, and water voles, reflects the silhouettes of red kites and kingfishers, provides employment, entices adventure, and allows time for carefree pilgrims to procrastinate and think. Following its banks is a grand way to go for a ramble.

The path begins, as the river does, in a meadow in the Cotswolds; its upper reaches lonely and wild, the meadows and banks the domain of waterfowl and willows; a collage of wild flowers, otters, fishermen and farmers. As the waters deepen and spread the settlements along its banks gradually begin to grow in both size and grandeur, and reaching Oxford, the solitude of the river slowly subsides and the trail becomes as much about historic towns, churches, abbeys and castles as it does the river. Lechlade, Abingdon, Wallingford, Henley ... they all owe their location to the Thames, and different eras, when the river was a life source, a place of conflict, a boundary, a mode of transport and the provider of leisure, which, thankfully—for us, at least—it remains to this day. Squeezing through the ancient Goring Gap, loomed over by the Chiltern Hills, you pass Runnymede—the site of the signing of Magna Carta—and Windsor Castle; where the aeroplanes overhead hint at the ominous size of the city to come.

Walking in London is not as blighted by sound, fury and concrete as many may imagine, as the river—and especially the route along the south bank in London—remains relatively countrified, at least as far as Putney, from which the approaching sights of Westminster and Tower Bridge offer comparably fine vistas to anywhere along the Thames' green and scenic upper reaches. Leaving central London, the regenerated dockland areas of East London (ideas of what constitutes 'wild' in the modern world are of course open to debate) lure you to your journey's end and the conclusion of a most enjoyable and magnificently-varied riparian ramble, quite like no other in Britain.

Yet the Thames Path is more than just a trek, more than a long walk, more than just a national trail; the river acts as a postgraduate course in the history of a nation, a counselor to the modern world, a reminder of the importance of protecting the natural habitats which gave us what we have....

But most importantly—at least, for those wishing to spend some time in the river's company, and indeed planning on doing so with the help of this book—the Thames Path is a fluvial escapade of the finest kind.
