Andros to Mykonos is one of the easier crossings in the northern Cyclades to plan. Ferryhopper lists a sailing every day of the year, three companies share the route, and in the warmer months you can choose between a quick high-speed run of just over an hour and a slower, cheaper ship that takes a little over two.
The two islands could hardly feel more different. Andros is green, walkable and low-key, with river valleys, stone-walled paths, sea captains' mansions in Chora and beaches you often share with a handful of Greek families. Mykonos is the opposite pole: Little Venice at sunset, the windmills, packed beach clubs and a nightlife scene that runs until morning. Many travellers do exactly this pairing on purpose, starting slow on Andros and finishing with a few loud nights on Mykonos.
The crossing times vary a lot, from 1 hr 10 min to around 2 hr 25 min, and the price gap follows the speed: on our 12 August 2026 sample the slower sailings cost €21 and the Seajets boats €32 to €36.80. For most people the choice comes down to whether you would rather save money or save an hour, and whether you want an open deck or an air-conditioned cabin seat.
Before booking, check which Mykonos harbour your ticket names, since Mykonos has an old port by town and a new port further north. Also think about Andros itself: the ferry harbour is at Gavrio on the west coast, and if you are staying in Chora or on the east side, getting to the boat is part of the journey.
