Datça is located 70-80 km west of Marmaris. The road from Marmaris (road number: D400) is the only way to arrive overland.
Although it’s possible to find direct bus services from main centres of the country, such as Istanbul during summer months; in the rest of the year your best bet is to arrive at Marmaris first, then transfer to another bus bound for Datça there.
There are ferries from Bodrum, arriving at the port on the northern coast of the peninsula. From there, Datça -which is on the southern coast of the peninsula- is a 10-15 minutes drive away.
Ancient city of Knidos is located on the tip of the peninsula (about 30 km west of Datça, near the village of Yazıköy). Although not impressive as it used to be at ancient times, this city had the famous naked Aphrodite, chipped by Praksiteles of Athens. Long missing (only its pedestal is still on the site), this statue once generated one of the earliest forms of tourism: People from all over Mediterranean world flocked to Knidos with the only intention of seeing it. There are two amphitheatres in Knidos, one of the facing Aegean Sea, while other has a view of Mediterranean proper.
The town (and the peninsula) is famous for its almond trees, and a local dessert made of almond and dried figs is remarkably tasty, so you may consider buying a few packages.
