Seasonal Considerations

The shoulder seasons of late spring and early autumn offer a good balance of reliable service with fewer crowds.

Winter schedules typically maintain the essential connections but with potentially reduced frequency. We recommend checking the latest timetables when planning your trip, especially if travelling outside the main tourist season.

Navigating the Ports

Departure Port (Kalymnos)

The main port of Kalymnos is located in Pothia, the island's capital. This bustling harbour is well-equipped to handle ferry traffic and provides essential services for travellers. The port area is conveniently situated near the town centre, making it easily accessible from most accommodations on the island.

To reach the port, you can use local buses that connect various parts of the island to Pothia, or take a taxi for more direct service. If you're staying in Pothia itself, the port is likely within walking distance. For those arriving by car, there is parking available near the port area, though spaces can be limited during peak season.

The port facilities include a waiting area, ticket offices where you can purchase or collect pre-booked tickets, and some small cafés and shops where you can grab refreshments before your journey. We recommend arriving at least 30-45 minutes before your scheduled departure to allow time for boarding procedures.

Arrival Port (Kos)

The main port of Kos is located in Kos Town, the island's capital and main commercial centre. Upon arrival, you'll find yourself conveniently positioned to explore the island or reach your accommodation. The port is integrated into the town's waterfront area, with many amenities within easy walking distance.

From the port, you have several transportation options to reach other parts of the island. Local buses connect Kos Town with major beaches and villages across the island, with the main bus station located about 10 minutes' walk from the harbour. Taxis are readily available at the port exit and can take you directly to your destination. For more independence, car and scooter rental agencies can be found near the port area.

The port area itself offers tourist information points, ATMs, cafés, restaurants, and shops. Many hotels and accommodations in Kos Town are within walking distance or a short taxi ride from the port, making for a smooth transition after your ferry journey.

Day Trip Possibilities

A day trip from Kalymnos to Kos is entirely feasible and offers a wonderful opportunity to experience another Dodecanese island without changing your base accommodation. With an average crossing time of just 37 minutes, you can maximise your time exploring Kos rather than spending it in transit.

For an ideal day trip, we recommend catching one of the morning departures from Kalymnos, which would get you to Kos by mid-morning. This gives you approximately 8-10 hours to explore the island before catching an evening ferry back to Kalymnos. The last departure from Kos at 23:05 allows for a full day of exploration or even dinner on Kos before returning.

A practical itinerary might include exploring Kos Town's historical sites in the morning, enjoying lunch at a waterfront taverna, spending the afternoon at one of the nearby beaches, and perhaps having an early dinner before catching your return ferry.

If you prefer a more relaxed pace or want to explore beyond Kos Town, consider extending your stay overnight. However, for those with limited time, a day trip provides a satisfying taste of what Kos has to offer while maintaining your base on Kalymnos.
