Greenwich Foot Tunnel: Walk Under the Thames

A curious piece of engineering links Greenwich to the Isle of Dogs beneath the river. It’s free, open daily, and gives a different perspective on the city’s maritime past.

What to Know

• Entrances: Round red‑brick domes by the river at Cutty Sark and Island Gardens.
• Access: Lifts and spiral staircases; bikes must be pushed.
• Safety: Well‑lit with CCTV; avoid cycling and keep to the left.

Pairings

Do the tunnel, take the DLR back, and finish with views from Greenwich Park hill.
