Lisbon=hills and stairs

 So Lisbon is extremely hilly. There are two large flat areas (Baixa and Belem) and everything else is uphill or downhill. There are many staircases, and many steep streets. The beautiful paving stones can be slippery when wet. Lisbon is a town for sensible walking shoes. Here are some random street scenes that may help. The bottom three are Sintra, about which more later.
