Banking on the Thames Path
Actually the longest riverside walk in Europe. Go explore!
Now the Thames Path is a National Trail footpath running for 180 miles along the banks of the river Thames.
Starting at the Thames Flood Barrier at Woolwich in South East London it runs along the banks of the Thames to Kemble in Gloucestershire. As it follows the banks of the river, the path is flat, making for easy walking and with much of the river being a busy waterway, there is usually plenty of activity to watch.
And here's another thing...it's actually the longest riverside walk in Europe. Go explore!
