From Source to Sea — A Journey Along England’s Most Famous River
Where meadows, towns, and the capital itself are united by one winding waterway.
The Thames Path is a 184-mile (294 km) National Trail following the River Thames from its source in the Cotswolds to the Thames Barrier in London. It’s one of England’s most varied long-distance walking routes, passing through peaceful countryside, historic towns, royal landmarks, and the heart of the capital before finishing at the Thames Barrier in Greenwich, London — where the river becomes tidal.
Walking holidays on the Thames Path offer something for everyone: easy riverside stages for day walks, multi-day self-guided adventures through the countryside, or a complete source-to-sea journey. With flat, well-marked paths, excellent transport links, and plenty of riverside stays, it’s one of the UK’s most accessible long-distance trails.
