Algete, looking over to La Sierra de La Cabrera.
Because everyone lives in high-rise flats, Madrid occupies a relatively limited ground area and the countryside starts very soon after leaving the City.
This is 20 miles from the city centre. Impossible to compare with other main capitals!
Madrilenos enjoy the vibrancy of living cheek by jowl! But they also like to escape to the country at weekends (which means a short walk of 20 minutes followed by a blow out feast of suckling pig or milk-reared lamb and mucho vino tinto).
