Described as a fashionable resort town, Porto Azzurro is the second port on the island of Elba; Portoferraio being the first. With good anchorage, a pretty square by the sea, pastel color houses and picturesque alleys, the town is a very popular summer destination.
Kudos to Girasoli for identifying the location of the header photo. A while back I had posted a photo of a sunset on Elba and linked it to my photo album on Slowphoto. The header photo is part of that album.
This is the picture I used before cropping.
