This walk enables those walkers who did not want to walk the whole 14 miles of Section 15 to have an opportunity to complete the London Loop. 

This section of the London Loop is largely level. Starting at Upminster Bridge we  follow the valley of the River Ingrebourne. On reaching the River Thames at Rainham we will meet any walkers who wish to walk only the Rainham to Purfleet section along the Thames.

After Rainham, there follows a fascinating final section of the London Loop which is full of history and atmosphere along the estuarial Thames. These include an ancient river ferry crossing point, extensive Thames side marshland and several  Second World War concrete barges. Lastly there is the RSPB bird reserve at Rainham Marshes formed on reclaimed land which we pass alongside.

We will finish the walk, and the London Loop, at Purfleet, which lies almost opposite Erith across the Thames, from where we started our epic circumnavigation of the London Loop back in May 2021.
