Camogli is certainly one of the most beautiful places of the Ligurian coast, where the houses grows in height;  and legend says that fishermens add floors every time the money would permit, ensuring that their wives could see their return from far away :-)
If you can go within one of the doors of the houses and walk up the stairs you'll be amazed by the slope of the stairs ... .
Wander quietly through the narrow streets and do not miss the cheese " focaccia " and the delights of the place. In the evening have a drinks on the square near the small harbour, the fishermen boats gently movement will take you to the magic of this unique place. 

Do not miss Camogli; this place which is reacheable by train (recommended) or by boat from San Fruttuoso (beautiful) or by car (not recommended). An idea for your day could be: Bus to Rapallo and Portofino, there you reach by boat / walk San Fruttuoso; on foot it takes  2.5 hours (bring water and a hat and swimsuit). In San Fruttuoso packed lunch, or in one of the restaurants on the beach and then , by boat to Camogli, which is about 10/15 minutes. boat timetables
