If you prefer to travel by car, a recommended option for car parking in Greenwich is to use the ‘park and glide’ facility at The O2. Until the end of July, you can park at The O2 for up to 4 hours absolutely free between 10am and 6pm when visiting ICON Outlet. Combine this with a river rip on board Uber Boat by Thames Clippers and you can visit The O2 and Greenwich in one fell swoop!
