The village of Portovenere occupies the suggestive promontory of Cape San Pietro, originated from the Mount Muzzerone, and closes westwards the big Gulf of La Spezia. The coast stretches very jagged creating various well defended creek, like the bay of Portovenere itself, and the inlets of Varignano and of the Graces. In front of Cape San Pietro there are Palmaria island and the islands of Tino and Tinetto, originally linked to the mainland. They present a sharper slope with falesias leaning on the sea, while on the opposite side the land is covered with a thick vegetation.
