Just a stone's throw from the heart of Portoferraio, you'll discover Spiaggia delle Ghiaie, a stunning expanse of smooth white pebbles that give the sea an incredible turquoise hue. The water here is crystal-clear, and since it's a protected marine area, the fish are so friendly they'll swim right up to you, making it a snorkeler's paradise. After a refreshing dip, you can relax on the shore or wander over to the nearby promenade for a bite to eat at one of the local cafes.
