AROUND the corner from Nazareth’s Old City market, in the shadow of 200-year-old Ottoman mansions, there’s a cobblestone street so narrow you can almost touch the houses on either side. An arrow pointing up some stairs is painted on one rough wall, along with the words “Jesus Trail.” It’s the de facto trailhead for a 40-mile hike through the Galilee region of Israel in the footsteps, more or less, of the man who made Galilee famous.
