Easy proximity to London made the Thames Valley enormously popular with the rich and powerful throughout the country's history. They built the lavish country estates and castles, including Windsor, that form the area's most popular tourist attractions today. Some of these, as well as Oxford and its university, are easy day trips from London. Consider exploring this stretch of the River Thames
by boat, either jumping aboard a cruiser or getting behind the oars. Windsor, Henley, and Marlow all make good starting points.
Once an aquatic highway connecting London to the rest of England and the world, the Thames was critical to the power of the city when the sun never set on the British Empire. By the 18th century the Thames was one of the world's busiest water systems, declining in commercial importance only when the 20th century brought other means of transportation to the forefront. Traditionally, the area west of London is known as the Thames Valley, and the area to the east is called the Thames Gateway.
Anyone who wants to understand the mystique of the British monarchy should visit Windsor, home to the medieval and massive Windsor Castle. Farther upstream, the green quadrangles and graceful spires of Oxford are the hallmarks of one of the world's most famous universities. Within 10 miles of Oxford the storybook village of Woodstock and gracious Blenheim Palace, one of the grandest houses in England, are both well worth your time.
The railroads and motorways carrying traffic to and from London have turned much of this area into commuter territory, but you can still find timeless villages and miles of relaxing countryside. The stretches of the Thames near Marlow and Henley-on-Thames are lovely, with rowing clubs, piers, and sturdy waterside cottages and villas. It all conspires to make the Thames Valley a wonderful find, even for experienced travelers.
