The Belvedere dello Schiaccone is the best view spot along the Amalfi coastline. It is about 600 to 700 feet up the hill (above the water) and the lookout is accessible from SS163 (this is the main road along the coast.) It is just west of Positano so if you are arriving from that direction it is before you get to the Positano turnoff. It is a great view of the three small isles that make up the archipelago of LiGalli. And a great view of Positano. If you missed it on the way it is worth getting in the car to go back to.
