Mesudiye Bays, which I described in detail in the list of places to visit in Datça, is located in the part of the peninsula facing the Mediterranean.
Preserving their naturalness with the support of the locals, the bays have become popular thanks to their calm structures. Even if you do not have your own vehicle, there are many points where you can watch the scenery on the curved road leading to the beaches, which you can easily reach via minibuses.
