Canary Wharf to Greenwich via foot tunnel
Through the new financial city, under the Thames, and up to the Observatory. Walked and written by the editor.

1. Crossrail Place Roof Garden
On top of Canary Wharf Crossrail station. Free tropical planting, five storeys above the street, in a space almost nobody knows exists. Open until 9pm.

2. West India Docks
The original 1802 dock is now a marina; the warehouses around it are offices and restaurants. The Museum of London Docklands in the north quay warehouse is free.

3. Mudchute Park & Farm
A city farm on a twenty-two-acre site of naturally formed land, created when the docks were dug out. Pigs, horses, and the best view of Canary Wharf from a field that has sheep in it.

4. Greenwich Foot Tunnel
Built in 1902, the tunnel runs 50 metres under the Thames and comes up in Greenwich Park. The Victorian lifts are the way to go.

5. Royal Observatory Greenwich
The prime meridian, the camera obscura, and the view back across the Thames to Canary Wharf. The hill is steep; the view from the top justifies it.
