We've shown the line starting from South Quay station on the DLR line, and from there it's an easy stroll beneath the modern towers of Canary Wharf to the north-east corner of the Isle of Dogs, from where you'll have an excellent view of the famous O2 Arena (formerly known as the somewhat-controversial Millennium Dome). Follow the riverside path as it winds south past Kelson Beach and Newcastle Draw Dock down to Island Gardens. Wave goodbye - temporarily - to the Thames and then head north to Mudchute farm.

The farm is quite extraordinary and a visit there grants you the unusual sight of sheep happily grazing open fields with huge, towering glass buildings behind. The middle park of the farm is amazingly peaceful, and at times you'll barely be able to tell that you're in one of the world's most famous cities.

Leave the tranquility of the farm behind and return to the city and then cross the Glengall Bridge and head due west to rejoin the Thames at the Sir John McDougall Gardens. Wander north along the river and then either cut back onto the northern section of the Isle of Dogs to get back to South Quay (which is the option drawn here) or continue strolling along the north bank of the river to whatever takes your interest!
