Enter start and destination and watch your route payed out.
The Transport for London Journey Planner shows you how to get from anywhere in London to anywhere else by public transport, on foot or by bike. Fancy a stroll from Trafalgar Square to Big Ben? Help yourself to a custom-built PDF route map. If you're travelling by road, you can use webcams to see exactly what the traffic's like. (But the best downloadable London maps are still on the BBC web site)
Aerial photos. Maps. Overlaid. Fantastic.
