The nearest airport is Dalaman (about 60 km north), with seasonal flights from across northern Europe and year-round services from Istanbul. Airport transfers to Hisaronu take just over an hour by private car or shuttle bus; a dolmus via Fethiye is cheaper but slower.
From Fethiye, 8 km away, dolmuses to Hisaronu and Oludeniz leave every fifteen minutes from the harbour station and the journey costs almost nothing. By rental car, follow the signs to Oludeniz out of Fethiye and Hisaronu sits at the top of the hill, just before the road drops down to the lagoon.
