A medieval stronghold built by the Benedictines of Monte Cassino protects a minuscule fishing village that can be reached only on foot or by water—a 20-minute boat ride from Portofino and also reachable from Camogli, Santa Margherita Ligure, and Rapallo. The restored abbey is now the property of a national conservation fund (FAI) and occasionally hosts temporary exhibitions and contains the tombs of some illustrious members of the Doria family. Plan on spending a few hours enjoying the abbey and grounds, and perhaps lunching at one of the modest beachfront trattorias nearby (open only in summer). Boatloads of visitors can make this place very crowded very fast; you might appreciate it most off-season.
