Muğla is a pleasant city on the side of a mountain, with a population of 61,000. Despite having the charm of a typical inland Aegean town, and being fairly close to (and, indeed the administrative centre of) the resort towns popular with international travellers (Bodrum, Marmaris, Fethiye to name a few), travellers often overlook Muğla.
Muğla lies on an elevation of 670 metres, and as such its significantly cooler climate is a welcome retreat from hot and sticky conditions of the coast.
Nearest airports are in Bodrum to west, and Dalaman to south, both of which are around an hour away from Muğla. Both welcomes domestic as well as international flights, especially from Europe.
From Izmir, take the motorway south to Aydın, then hit D550 there.
