Bodrum - Milas Airport Transfers

This modern airport, built during the late 1990s, is 36 km (21 miles) northeast of Bodrum, 16 km (10 miles) south of Milas, just north of the Güllük intersection

The International Terminal (Dis Hatlar) and Domestic Terminal (Iç Hatlar) are about 1 km apart, separated by grassy fields. It's about a 15-minute walk across the fields between the terminals, longer if you walk on the roads.
Unless you are part of an organized tour being met by a bus or minibus, you'll probably have to take an expensive airport taxi. Find other travelers with whom to split the cost.
