Adamas or Port Milos is the only harbor in Milos. It is near the end of Milos Bay, one of the largest natural harbors in the Mediterranean, which is the volcano`s caldera. Because of the size of the bay there can be a rather uncomfortable ground swell and also the ferry wash can be substantial.

The harbor provides quite good, if not always comfortable, shelter from the meltemi (the Etesians) (the Etesians), but it is exposed to southerlies. Visiting yachts moor stern-to the small yacht quay, where there is space for around ten boats (although the depth shallows at the western end) or along the outside arm of the tripper boat harbor, where there is space for a further 10-12 yachts on an anchor moor.

An alternative is to anchor off in the bay to the east, clear of the small craft moorings. Here the holding in the mud and weed bottom is good.
