The Thames River starts in a place called Thames Head, located in the Cotswolds, an area in England known for its beautiful hills 🏞️. It flows through many famous cities, including Oxford and London! The river passes through a mixture of countryside, towns, and cities, making it a fascinating journey. There are many tributaries, which are smaller rivers that flow into the Thames. The river eventually flows into the North Sea 🌊 at a place called Estuary, where it meets huge waves and tides! The Thames is tidal, so sometimes the water level goes up and down!
