Running for 180 miles (288 km) from the river's source in rural Gloucestershire to the Thames barrier, the Thames Path is England's newest National Trail and one of the most varied and accessible of the country's long-distance paths. The Countryside Agency's acorn waymarks lead the walker through tranquil water meadows, past the dreaming spires of Oxford and the pageantry of Windsor and Hampton Court, through the heart of the capital, to London's Docklands and beyond. This is the official guide to the Path and will be invaluable to the long-distance walker and weekend stroller alike.
