Hike up the hill from Turó del Pollo and get an eyeful of an ancient (6th century B.C.) Iberian settlement at Puig Castellar. This is best saved for a cool fall or spring day as at this height the sun can be fierce. Take a picnic lunch, or at least a bottle of water, so that you can relax and take in the sweeping views of Barcelona for as long as you like.
