Ferries between Naxos and Milos don’t start until June 7th (one each way, every day after that). Ferries between Santorini and Milos start April 28th and there is one every day in each direction. And there are always ferries between Naxos and Santorini. So if the dates work I would fly to Santorini (the longest leg) then ferry to Milos then Naxos and back to Athens. But if you need to travel between Naxos and Milos before the 7th then ferry Athens to Milos to Santorini to Naxos and back to Athens.

This island is perfect for people looking for a quiet and less touristy Caribbean experience. At the same time, you can find some interesting nightlife here to stimulate you after a day relaxing on the beach.
