DS is public transport mad and we have explored London by tube, bus, ferry, DLR, overground (we live an hour away by train). Clearly there is a tram-shaped hole here, which we plan to fill next month.
We'll get on the tram in Wimbledon and do the whole length of the network. It's not a part of London I know and, other than Croydon Museum, I am short of ideas of places to visit on the way. Recommendations of nice parks, cafes, anything really, would be really welcome!
