Overview
Kos is the third-largest island in the Dodecanese archipelago, sitting in the southeastern Aegean Sea close to the Turkish coast. It is an island of genuine contrasts: flat, cycling-friendly terrain in the centre gives way to the forested hills of Mount Dikeos in the east, while busy harbour-front bars and restaurants coexist with quiet Byzantine chapels and Hellenistic street grids.
The island has been inhabited and contested for millennia — Minoans, Mycenaeans, Dorians, Persians, Romans, Knights of St John, Ottomans, Italians, and finally Greeks have all left visible marks. That layered history gives Kos Town an unusually rich streetscape for a medium-sized Aegean resort island.
Tourism is the primary economic driver today. Package holidays concentrate around Kos Town, Kardamena, and Tigaki, but the island is large enough that quieter corners — Kefalos in the southwest, the villages of the Asfendiou massif — remain genuinely off the resort circuit.
Before You Go
Visas
Kos is part of Greece and therefore the Schengen Area. Visa requirements vary significantly by nationality and are subject to change. Check TravelerPulse's Visas section and the official Greek immigration authority website for current, nationality-specific rules before booking.
Health
No vaccinations are specifically required for Greece, but standard travel health precautions apply. EU/EEA citizens should carry a valid European Health Insurance Card (EHIC) for access to public healthcare on the same terms as Greek nationals. Non-EU travellers should arrange comprehensive travel insurance covering medical evacuation, as the island has limited specialist facilities; serious cases are sometimes transferred to Rhodes or the Greek mainland.
What to pack
- Comfortable walking shoes for ancient-site cobblestones and uneven terrain
- High-SPF sunscreen — summer UV levels are intense
- A light layer for evenings in spring and autumn
- Modest clothing (covered shoulders and knees) for churches and monasteries
- A padlock if staying in hostel accommodation
Money
ATMs are available in Kos Town and larger resort areas. Cards are accepted at most hotels and restaurants in tourist zones, but carry some cash for village tavernas, markets, and bus tickets. Verify ATM availability and fees with your bank before travelling.
Getting There
By Air
Kos International Airport (IATA: KGS), also known as Hippocrates Airport, is located on the northeastern coast of the island roughly 26 km from Kos Town. It receives direct charter and scheduled flights from many European cities during the summer season (roughly April–October). Year-round connectivity is more limited; some travellers route via Athens during the off-season. Verify current routes and schedules with airlines or booking platforms, as they change each season.
By Ferry
Kos is well connected to Piraeus (Athens' main port), Rhodes, Patmos, Leros, Kalymnos, and several other Dodecanese islands. Journey times and frequencies vary considerably by season and operator. The main ferry port is in Kos Town. Check current schedules on the Greek ferry booking aggregators (e.g., Ferryhopper, OpenSeas) or directly with operators such as Blue Star Ferries and Dodekanisos Seaways — schedules shift seasonally.
From Turkey
Day-trip boats and small ferries operate between Kos Town and Bodrum, Turkey, when conditions and bilateral agreements allow. Crossing times are short (around 20–30 minutes), but immigration formalities apply in both directions. Confirm current operational status and entry requirements before assuming this route is available.
Getting Around
Bicycle
Kos Town and the flat central plain are genuinely cycling-friendly by Greek island standards. A well-used cycle path runs along the northern coast toward Tigaki. Bicycle rental shops are plentiful in Kos Town; verify current rates locally.
Bus (KTEL)
Kos has a public bus network (KTEL Kos) covering the main settlements including Tigaki, Marmari, Kardamena, Kefalos, and Mastichari. Services are more frequent in summer. Check the current timetable at the KTEL office in Kos Town or on their official site, as schedules change seasonally.
Taxi and Ride-Hail
Taxis are available from the main rank near the port in Kos Town and can be flagged on main roads. Agree the fare or confirm the meter is running before departing. Ride-hail apps have limited penetration on the island; verify locally.
Car and Scooter Rental
Rental agencies are numerous in and around the airport and Kos Town. A car is practical for reaching the mountain villages and the Kefalos peninsula. An international driving permit is recommended for non-EU licence holders, though requirements should be confirmed with the rental company. Scooter rental is popular but carries higher risk — helmets are legally required.
Local Boat
Excursion boats from Kos Town harbour serve neighbouring islands and beaches not easily accessible by road. Schedules are posted at the harbour.
Things to See & Do
History and Archaeology
- Asklepion: The most significant ancient site on the island, this sanctuary and medical school is closely associated with Hippocrates, the ancient physician. It sits on a hillside about 4 km from Kos Town with views toward Turkey. Opening hours and admission fees — verify on-site or via the Greek Ministry of Culture website.
- Archaeological Museum of Kos: Housed in an Italian-era building on Eleftherias Square in Kos Town, the collection includes Hellenistic and Roman sculpture, mosaics, and artefacts from the Asklepion and wider island. Verify hours and fees before visiting.
- Ancient Agora and Harbour Quarter: Roman-era ruins, including a colonnade street (the Cardo), temple remains, and the Casa Romana (a reconstructed Roman villa with mosaics), are scattered across Kos Town and walkable from the centre.
- Neratzia Castle (Castle of the Knights): The 14th–15th century fortress of the Knights of St John guards the harbour mouth. It incorporates ancient spolia — columns and inscriptions recycled from earlier structures.
- The Hippocrates Plane Tree: A very large Oriental plane tree in the town centre, traditionally — though not literally accurately — said to have been planted by Hippocrates himself. Worth seeing; the tree is genuinely ancient and very large.
Beaches
Kos has beaches along much of its northern and southwestern coastline. Tigaki and Marmari offer long sandy stretches on the northern coast. Paradise Beach and Camel Beach (Polemi) near Kefalos are popular with younger visitors. Agios Stefanos near Kefalos has the added interest of Early Christian basilica ruins visible in the shallows. Water quality varies by season — look for Blue Flag designations as a quality indicator.
Villages and Nature
The villages of the Asfendiou area on the slopes of Mount Dikeos — Zia, Asomatos, Evangelistria — offer traditional architecture, cooler temperatures, and island views. Zia is the most visited and most developed for tourism; others are quieter. The summit of Mount Dikeos (846 m) can be hiked; trail conditions vary, so ask locally before attempting in summer heat.
Food & Drink
What to Eat
Kos shares the culinary vocabulary of the broader Greek and Dodecanese tradition. Fresh fish and seafood — caught locally or from regional waters — are a mainstay of the better tavernas. Look for grilled octopus, fried courgette flowers, local olives, and fresh cheese. Lamb and goat dishes feature inland. The island produces honey that locals regard highly.
Where to Eat
Kos Town has the widest restaurant choice, ranging from harbour-front tourist tavernas to small neighbourhood places serving a more local clientele. For the latter, explore streets away from the waterfront. The villages of Zia and Platani (the latter with a Turkish-Greek cultural influence from the island's Muslim community) have tavernas worth the short trip. Kardamena and Tigaki have resort-oriented restaurant strips.
Drinking
Greek coffee, frappé, and the ubiquitous cold-brew freddo espresso are the daytime staples. Ouzo and tsipouro remain the traditional spirits. Local wine is produced in small quantities; imported Greek wines from Santorini, Crete, and Nemea are commonly available. Kos Town's bar scene is concentrated around the old town and harbour area and can be lively in summer — those seeking quiet should choose accommodation away from these streets.
Dietary Needs
Vegetarians and vegans can eat reasonably well — Greek cuisine has a strong tradition of legume and vegetable dishes (mezedes, fava, gigantes). Gluten-free options are less consistently labelled outside higher-end establishments; communicate needs clearly to staff.
Shopping
Kos Town's central market area and streets around Eleftherias Square have the broadest range of shops. Genuine local products worth seeking out include locally produced honey, olive oil, dried herbs, and ceramics. Sponges — a traditional Dodecanese product — are sold widely, though verify origin if authenticity matters to you.
Beware of mass-produced 'souvenir' goods that are common throughout Greek tourist areas. For better-quality local crafts, smaller artisan shops or producers in the villages are a more reliable bet than the busiest tourist streets. Sunday markets (laiki agora) in Kos Town sell fresh produce and household goods and are worth visiting for a local atmosphere if your visit coincides.
Practical Information
Emergency Numbers
- European Emergency Number: 112 (police, fire, ambulance — works throughout the EU)
- Tourist Police: A separate branch of Greek police that can assist travellers; look for their office in Kos Town or ask at your accommodation.
Medical
Kos has a public hospital (verify current location and contact details locally or via your accommodation). Pharmacies (indicated by a green cross) are present in Kos Town and main resorts; pharmacists can advise on minor ailments. Travel insurance with medical coverage and repatriation is strongly recommended for all visitors.
Connectivity
Mobile coverage from major Greek networks is good in Kos Town and resort areas; it can be patchy on mountain trails and in some rural areas. EU travellers benefit from EU roaming rules (verify your plan's terms). SIM cards from Greek operators are available in the town. Free Wi-Fi is offered at many hotels, cafés, and some public spaces.
Opening Hours
A general pattern sees shops open mornings, close for a midday break (roughly 2–5 pm), and reopen in the evening — though tourist-area businesses often stay open continuously in peak season. Museums and archaeological sites typically close one day a week (often Monday or Tuesday); verify current hours before visiting as they change seasonally and with staffing.
Tipping
Tipping is appreciated but not obligatory. Rounding up the bill or leaving 5–10% at restaurants is conventional. It is common to leave small change at cafés.
Safety
Kos is generally a safe destination for travellers. Petty theft (bag snatching, pickpocketing) is the most commonly reported issue, particularly in crowded tourist areas and around the ferry port. Standard precautions — keeping valuables secure, not leaving bags unattended on beaches — are sufficient for most visitors.
Road safety deserves attention. Scooter and motorbike accidents involving tourists are a recurring problem across Greek islands, including Kos. If renting a two-wheeler, wear a helmet (legally required), drive cautiously on unfamiliar roads, and ensure your travel insurance covers motorised vehicles.
Sea safety: flag systems on organised beaches (blue/green = safe, yellow = caution, red = no swimming) should be respected. The northern coast can have strong winds — a factor for water sports participants. In summer, heat and sun exposure are genuine hazards; stay hydrated and limit midday outdoor exertion.
Kos is located in a seismically active region. Earthquakes occur; the island experienced a significant one in 2017. Familiarise yourself with basic earthquake safety procedures.
Local Culture & Etiquette
Kos has a more culturally layered identity than many Aegean resort islands. The presence of a small Muslim community, descendants of Ottoman-era settlers, centred around Platani village and the town mosque, gives the island a subtly different character from most other Greek islands. The coexistence of a working mosque and Ottoman fountain alongside Byzantine churches and ancient ruins reflects the island's long history of shifting sovereignties.
The legacy of Italian administration (1912–1943) is also visible in Kos Town's urban planning and architecture — wide boulevards, the market building, and the governor's palace all date from this period. The Italians also conducted significant archaeological excavations, partly explaining the extensive exposed ruins in the town centre.
Religious festivals (panigiri) tied to saints' days animate village life particularly in summer and early autumn. These are genuine community events rather than tourist performances; visitors who attend respectfully are generally welcome. Orthodox Easter is the most significant religious period in the Greek calendar and transforms the atmosphere of the island if your visit coincides.
Dress modestly when visiting churches and monasteries. Topless sunbathing is tolerated on many beaches but is generally not appropriate in town or village settings.
