FIJI Water has linked up with le cool London to launch a series of interactive self-guided walking tours tracing the routes of London's subterranean rivers.
Curated by le cool London editor Mat Osman, the Winter edition launches this week and focuses on the River Neckinger which flowed into the Thames at what is now St Saviour's Dock.
Walkers are invited to follow an audio podcast featuring actor Philip McGinley, local historians and experts such as skyscraper specialist Herbert Wright and others.
The Artesian Wanders podcast, Google map for smartphones and a printable map are all downloadable free via the le cool London blog from Thursday.
Before hitting the SE1 streets, would-be walkers are welcome to learn more and meet the team behind the tours at the Artesian Wanders launch party where there will be complimentary drinks from Palm Breweries and music from DJs Fear of Theydon and Oliver Keens.
