At the beginning of Beçin village, about 6km south of Milas on the road to Ören, a steep signposted road climbs to Beçin Castle. Originally a Byzantine fortress, it was remodelled by the short-lived Menteşe beylik (principality) in the 14th century. The castle, crowning a 210m-high rocky outcropping, offers great views of Milas below from its walls.
The ruins of more MenteÅŸe-era structures can be seen across the valley and up another hill, including the °Ä±³úı±ô³ó²¹²Ô (Red Caravanserai), Bey Konağı (Bey's Residence), Orhan Mosque, the Büyük Haman (Great Bathhouse) and the wonderfully restored Ahmet Gazi Madrasah. You can borrow an English-language guidebook from the ticket booth. Half-hourly dolmuÅŸes run between Milas and Beçin village (₺3).
