The cost of island hopping in Greece in 2026 varies wildly depending on the distance, the type of vessel, and the time of year. Short hops between neighboring islands in the Cyclades (like Naxos to Paros) can cost as little as €15 to €25 on a standard slow ferry. For longer routes on high-speed catamarans (like Athens to Mykonos or Santorini), prices typically range from €60 to €90 for a one-way economy ticket. If you are traveling with a car, expect to pay significantly more, often between €80 and €150 just for the vehicle. Overnight ferries to distant islands like Rhodes or Crete offer "cabin" options that can exceed €200. During the peak summer months (July and August), prices are at their highest and tickets often sell out weeks in advance. To save money, many travelers use the "Greek Island Pass" offered by Eurail/Interrail or book the "slow" car ferries (like those operated by Blue Star Ferries), which are much cheaper and offer a more scenic, stable ride than the faster, bumpy Seajets. Booking online in advance is essential to secure the best "early bird" rates.
