Regent's Canal stretches all the way from Paddington to Limehouse, and a wander down the length of it reveals all of London's diversity. Take a guided meander along the water to see awesome architecture, two popular markets and some tourist hotspots, too. The tour will end at The Proud Archivist, a unique space with a coffee shop, restaurant, art gallery and library. Nice, huh? Please arrive on time or the tour will leave without you. The tour lasts around three hours.
