There are 2 daily ferries (2.5-4 hours) and 6 daily flights (40 minutes) from Athens to Milos. If you have the time (or hate small planes) we recommend you take the ferry at least one way.
Option 1 -- 7:40 am departure from Piraeus port in Athens, 11:00 am arrival at Adamas port in Milos via SEAJETS
Option 2 -- 9am departure from Piraeus port in Athens, 12:20 arrival at Adamas port in Milos via SEAJETS
There is a small domestic airport in Milos (MLO) with flights from and to Athens (ATH). If you book early enough, flights can often be cheaper than the ferries and it is certainly quicker (40 minutes). The scenery as you fly over the island is quite wonderful so make sure to book a window seat!
AEGEAN/OLYMPIC has 4 flights/day
SKY EXPRESS has 2 flights/day
Transportation will be provided to/from all events; however, we highly recommend renting a car if you want to explore the island (cabs can be expensive).
Car rentals companies
You can also rent ATVs and motorcycles. One good thing about them is that you can park easily at popular beaches which sometimes have limited parking.
