Using the Greenwich Foot Tunnel (South lift out of order) the walk goes through the Royal Naval College and Greenwich Park then climbs up to Point Hill for views across London before returning to Greenwich Park for more views of London. After crossing the Park there is some urban walking to reach Charlton House for lunch. There are two cafes and a pub (no food served but you are welcome to eat your own lunch there). The walk continues through Charlton Park, descends through the Maryon Parks to the Thames Barrier and then along the Thames Path to North Greenwich.
