Once at Bodrum airport there are 2 ways to get to Horizon Sky Beach Resort depending on what time you arrive.

1) By Boat
This is by far the nicest way to arrive at the resort. At Bodrum airport get a taxi to Gulluk which is 20 minutes away and costs approximately 40 TL ( £18 ). At Gulluk ask to be shown to the Horizon Sky boat which will take you across the bay to the resort. The view across this bay is stunning and a great way to meet other holidaymakers. Full boat timetable can be obtained from the owner but in peak season runs from 08:15 to 00:30. Once at the Horizon Sky jetty cars will be waiting to take you up to key security/ your apartment.

2) By Car
If you are arriving outside the boat timetable or you prefer direct transfer from Bodrum airport to the resort, the journey time by car is approximately 45 minutes. Taxis can be easily obtained at the airport- ask to go to Horizon Sky, Iasos. Transfers can also be booked in advance ( approximately £35- £45 ):
