Islands, La Spezia
I had the chance to visit the nearby islands with a local guy I had met at a club and found it simply enchanting. In a seculed beach he was able to ride the "baloney pony' until he could not stand it anymore! What a great place! I'm cuming back soon!
From Portovenere you can take a boat trip (half a day) to nearby Isola (Island) Palmaria and visit Grotta Azzurra (Cave). Hmm... I was looking at the island only :-).
