• You can take the boat to Sifnos from Piraeus Port. It is easy to get there; from Athens’ Airport you take the suburban railway that connects the airport directly to Piraeus. Then, ask your travel agent or an agency in the port for your boat’s location.
• If you’d like you can buy your boat tickets in advance through an agent or online. If you choose not to, there are many ticket agencies in Piraeus to assist you but if you’re traveling on a weekend in July or August it would be preferable to book in advance.
• The boats usually take you to Sifnos in two to five hours, depending on the boat type and speed. Generally they stop at Kythnos and Serifos islands before getting to Sifnos, and if you want you can find boats that get directly to Sifnos to get there faster.
