Cities Along the River Thames: From Source to Sea

Major Cities the Thames Flows Through

The River Thames winds 346 km (215 miles) across southern England, connecting historic towns and the capital:

• Oxford: The "City of Dreaming Spires," where the Thames (locally called the Isis) passes iconic college boathouses.
• Reading: A major commercial hub at the confluence with the Kennet.
• Windsor: Home to Windsor Castle, the river here is broad and scenic, lined with royal parks.
• London: The tidal Thames defines the capital, flowing past the Houses of Parliament, Tower Bridge, and the Thames Barrier before reaching the North Sea.

Numerous smaller towns—Henley, Marlow, Kingston, Richmond—also grace its banks, each with a unique riverside character.
