Four km southwest of Platanos is Lakki, the main port of Leros. It is secure and safe and is the largest natural harbour in the Mediterranean. It has modern port facilities and two units for servicing yachts. It looks like a huge lake, with an open space of only 400 meters towards the sea. This natural characteristic was the reason why it was called Porto Lago (port - lake) by the Italians and was chosen as a naval base.Agia Marina is one of the island’s two ports. It’s a small coastal village that has grown over time to be united with Platanos, the island’s oldest inhabited area and capital. Presently, this unified town is the island’s administrative and commercial centre. From a distance it would appear that this small town has spread out over the slopes of two mountains, with homes stretching from the coast to the foothills of Kastro. However, as you approach, the true beauty of this jewel in the Aegean is unravelled before your very eyes. The acquaintance to Agia Marina starts at the port, with the fortress of Bouzi or Bourtzi at its entrance and the towering lighthouse on its edge, to the side pier and the quaint dry dock and the well-preserved historical windmill.
Crithoni Paradise is the biggest hotel in Leros and is constructed in complete accordance with the environment, the tradition and the history of Leros island in Greece,
