We only spent one day in this area when I was studying abroad in Florence. One day. But I assure you, we spent it well. Arriving early in the morning, we hiked a trail that connects all the Cinque Terre towns. We were close to the ocean, high up on the cliffs, and walking through vineyards, and the best part is, the trail winds through all five villages so you can experience those too. This place may be popular and crowded, but it is charming and gorgeous, and so worth a visit (I’d recommend more than one day). I’d love to get back there myself and do some serious photography.
