The Bay of Moudros is one of the largest natural harbors of the Mediterranean. While it is in general safe, it is large enough to develop an uncomfortable swell during strong winds. This fact, coupled with murky water, makes it not very attractive for yachts.
A quay has been constructed at Moudros itself, which offers alongside mooring for 6-8 yachts and (on the south side) reasonable shelter from the meltemi (the Etesians). Water and electricity is available on the quay. Good taverns ashore.
If you wish to anchor, there are many coves in the bay, but during the meltemi (the Etesians), which blows here in violent gusts from the NE, it is best to anchor just to the S of the town, located on the E side of the bay, if no space is available on the quay.
