The port of Adamantas was founded in 1835 and is considered one of the largest and safest natural ports in the Mediterranean. The position of Milos among the islands of the Cyclades allows passenger ships to connect with other popular destinations. Also, with the piers and moorings it has, it has the ability to serve other vessels.

In recent years, the island has been developing rapidly in the cruise sector as Milos is an intermediate stop for popular destinations in the Cyclades. At the same time the number of yachts is constantly increasing, especially during the summer months.
