Alcalá seems to be very close here. However, it was a two hours walk from the place where I am staying as you cannot cross the river at the barrage of the Henares to access the hill/mountain. That’s my suggestion for city development: Build a bridge and an escalator from New Alcalá and the place will be teeming with people. Well, maybe not. There weren’t many people at the enchanting water front or the meadows of the flood plain. Oh, if you look carefully, you’ll notice the high-rise buildings on the horizon. This is Madrid.
