At the beginning of Beçin village, 1km south of the Bodrum–Muğla highway on the road to Ören, a signposted road climbs to Beçin Kalesi, on a rocky outcropping. Originally a Byzantine fortress, it was remodelled by the short-lived,14th-century Menteşe Empirate.
The high castle walls, topped by a giant Turkish flag, offer great views of Milas below. More Menteşe-era structures can be seen across the valley, including the Kızılhan (Red Caravanserai), the Ahmet Gazi tomb and the restored medrese . You can borrow a guidebook from the castle ticket booth.
Half-hourly dolmuşes run between Milas and Beçin village (₺2.25).
