20-min ferry from Bodrum to Kos (Greece). Passport + Schengen-valid visa required. Cheaper to do as a day-trip than to stay overnight.
The Bodrum–Kos ferry is one of the quickest international crossings in the world: just 20 minutes from the marina in central Bodrum to the Greek island of Kos. What most visitors get wrong is assuming they can just show up and hop on. In reality, you need a valid passport and a Schengen visa (or a Greek-issued visa-on-arrival, which is limited and not guaranteed). The day-trip is far cheaper than an overnight stay, and it lets you experience a different country—and a different vibe—in a single morning or afternoon. Kos Town is walkable from the ferry terminal, with its harbourfront cafés, ancient ruins, and the famous Plane Tree of Hippocrates. Beyond town, the island offers the Asklepion (Hippocrates' medical school) and long sandy beaches like Tigaki. But the real draw is the contrast: stepping from Bodrum's lively Turkish resort into Kos's quieter, more laid-back Greek island atmosphere.
Kos has been inhabited since the Bronze Age and was a major centre of the Hellenistic period. It is best known as the birthplace of Hippocrates, the father of modern medicine, who taught at the Asklepion around the 5th century BC. The island was ruled by the Knights of St John from 1309 to 1522, who built the Neratzia Castle at the harbour entrance. After a brief Venetian period, Kos fell under Ottoman rule from 1523 until 1912, when it was annexed by Italy. The Italians left a mark with neoclassical buildings in Kos Town. The island was unified with Greece in 1947. Today, Kos is a popular tourist destination, and its proximity to Bodrum makes it a natural day-trip for visitors to Türkiye. The ferry crossing itself is a reminder of the close ties—and the border—between the two countries.
Arrive at Bodrum Ferry Port at least 45 minutes before departure. You'll go through Turkish passport control before boarding. The ferry crossing is 20 minutes, and on arrival in Kos you'll clear Greek passport control. The whole process is efficient but can have queues in summer. A day-trip gives you roughly 6-8 hours on the island, depending on the ferry schedule. Wear comfortable shoes for walking in Kos Town; bring sunscreen and a hat. If you plan to visit the Asklepion or Tigaki beach, take the early ferry to maximise time. The return ferry is the same short crossing. No special dress code, but remember you're entering a different country—respect local customs. The best months are May to October; in winter, ferry schedules are reduced.
A day-return ferry ticket with Bodrum Ferryboat Association or Yeşil Marmaris Lines costs around €35 (about 1,200 TL in 2026). Asklepion entry is €8 (approx. 280 TL). Bus from Kos Town to Tigaki is about €2.50 each way. Taxi to Tigaki costs €20-25. Sunbeds at Tigaki beach around €10. Budget roughly €60-80 per person for the day, including lunch and a drink.
Skip the overpriced tourist-trap restaurants right on Kos Town harbour—they charge double for mediocre food. Instead, walk one street back for better value. The Castle of the Knights is interesting but small; if you're short on time, prioritise the Asklepion or beach. Don't bother with the 'Hippocrates Tree' as a major attraction—it's just a tree in the square, often crowded.
Yes, you need a valid passport and a Schengen visa to enter Greece. Turkish nationals may apply for a Greek-issued visa-on-arrival, but this is limited and must be arranged in advance. EU citizens can enter freely. Without the correct visa, you will not be allowed to board.
The crossing takes just 20 minutes. It's a passenger-only catamaran that departs from Bodrum Ferry Port and arrives at Kos Town port. The short duration makes it ideal for a day-trip.
The main operators are Bodrum Ferryboat Association (BFA) and Yeşil Marmaris Lines. Both charge around €35 for a day-return and have similar schedules. BFA is slightly more popular, but both are reliable. Book ahead in summer.
Yes, it's only 4 km from Kos Town. You can walk (20 min), take a bus, or taxi. The site takes about 1-2 hours to explore. If you take an early ferry, you can easily fit it in along with some time in Kos Town.
Yes, if you want a proper beach day. It's a long sandy beach with clear water, about 12 km from Kos Town. Take a bus (€2.50) or taxi (€20-25). Sunbeds cost around €10. It's quieter than town beaches and perfect for swimming.
