Overview
Editorial note: The request specifies 'Kos, Cyprus (state).' No settlement, district, or locality named Kos exists within Cyprus. Kos is a well-known Greek island in the southeastern Aegean Sea, part of the Dodecanese island group and administratively part of the South Aegean region of Greece. This guide covers that destination. If you were looking for a specific village or locality in Cyprus, please verify the name and resubmit.
Kos is the third-largest island in the Dodecanese, covering roughly 290 square kilometres, and sits close to the Turkish coast near Bodrum. It is the birthplace of Hippocrates, the ancient physician often called the father of medicine, and this heritage is a defining thread through the island's identity.
The island combines a modest but well-preserved medieval old town—shaped significantly by the Knights of St John—with long sandy beaches, a flat interior that makes cycling practical, and a lively resort scene centred on Kos Town and Kardamena. It draws a broad mix of travellers: history enthusiasts, beach holiday visitors, cyclists, and day-trippers from Turkey.
Beyond the main town, the island rewards exploration. Villages such as Zia in the Dikeos mountain range offer cooler temperatures and views across to neighbouring islands, while quieter beaches on the south coast contrast with the busier northern strips.
Before You Go
Visas
Kos is part of Greece, which is a member of the European Union and the Schengen Area. Visa requirements vary by nationality. Check TravelerPulse's Visas section and the official Greek Ministry of Foreign Affairs website for current, authoritative requirements before travelling.
Health
No specific vaccinations are required for most travellers, but standard up-to-date immunisations are advisable. Tap water is generally considered safe in Kos Town; in rural areas, bottled water is widely available. The summer sun is intense—sunscreen, hats, and hydration are practical necessities from June through August. Verify any health advisories with your national health authority before departure.
What to pack
- Light, breathable clothing for summer; a layer for evenings in spring and autumn
- Comfortable walking shoes for archaeological sites (uneven terrain is common)
- Sunscreen and a reusable water bottle
- Cycling gear if you plan to use the island's bike paths
- EU residents should carry their European Health Insurance Card (EHIC) or equivalent; all travellers should arrange adequate travel insurance
Getting There
By Air
Kos Island International Airport 'Hippocrates' (IATA: KGS) is located approximately 25 kilometres southwest of Kos Town, near the village of Antimachia. It receives scheduled and charter flights from Athens (operated by Olympic Air and Aegean Airlines) as well as seasonal direct international flights from a number of European cities, particularly during the April–October tourism season. Verify current routes and schedules directly with airlines or booking platforms, as services change seasonally.
By Sea
Kos is connected to Piraeus (Athens' main port) and other Dodecanese islands by ferry services. Journey times and frequencies vary by operator and season. The main operators on Aegean routes include Blue Star Ferries and Dodekanisos Seaways for inter-island connections; verify timetables on their official websites or through the Greek port authority. There is also a regular passenger/vehicle ferry link between Kos Town and Bodrum, Turkey—check current schedules and any border crossing requirements locally.
Getting from the Airport
Taxis are available at the airport. A public bus (KTEL) connects the airport to Kos Town, though frequency is limited; verify the current timetable locally or at the airport. Car hire desks are present at the airport if you prefer to drive from arrival.
Getting Around
Cycling
Kos is famously flat in its northern and central areas, and the island has dedicated cycle paths, particularly the well-maintained route running along the coast between the airport and Kos Town and beyond. Bicycle hire is widely available in Kos Town and resort areas; this is one of the most practical and popular ways to explore.
Bus
KTEL Kos operates public buses linking Kos Town with major villages and resort areas including Tigaki, Marmari, Mastichari, Kardamena, and Kefalos. Timetables are seasonal; verify current schedules at the bus station in Kos Town or on the KTEL website.
Taxis and Car Hire
Taxis are available in Kos Town and larger resort areas. Car hire is plentiful and can be a good option for reaching more remote beaches and the mountain villages. Scooter and quad hire is also common, though caution is warranted—road conditions and traffic behaviour can be unpredictable on narrower routes.
Boat Trips
Day trip boats operate from Kos Town harbour to nearby islands including Nisyros (with its active volcano), Kalymnos, and others. These are popular excursions; availability is seasonal, so check locally.
Things to See & Do
Archaeology and History
- Asklepion: One of the most important ancient healing sanctuaries in the Greek world, set on a hillside with tiered terraces and views toward Turkey. This was where Hippocratic medicine was practised and taught. Verify current opening hours and admission fees with the local archaeological service before visiting.
- Kos Town Archaeological Museum: Houses finds from various excavation sites across the island, including Roman and Hellenistic pieces.
- Ancient Agora and Roman Odeon: Substantial ruins are accessible in and around Kos Town itself, some in the middle of the modern town.
- Neratzia Castle (Castle of the Knights): A medieval fortification built by the Knights Hospitaller, situated at the harbour entrance. The Plane Tree of Hippocrates nearby—claimed (with some poetic licence) to be where Hippocrates taught—is a popular landmark.
Beaches
The island has a wide variety of beaches. Tigaki and Marmari on the north coast are long sandy stretches popular with families and windsurfers. The south coast around Agios Stefanos and near Kefalos tends to be quieter, with clearer water; the ruined Early Christian basilicas at Agios Stefanos add historical interest. Paradise Beach is a well-known party-oriented beach.
Villages and Nature
Zia, in the foothills of Mount Dikeos, is the most visited inland village and known for sunset views. The Dikeos massif itself offers walking trails; the summit reaches around 846 metres. The landscape in the island's interior is largely agricultural and peaceful compared to the coastal resorts.
Day Trips
Nisyros, a neighbouring volcanic island with a dramatic caldera, is one of the most worthwhile excursions from Kos. Boats run seasonally from the harbour.
Food & Drink
What to Eat
Kos shares the culinary traditions of the broader Dodecanese and Greek Aegean cuisine. Fresh seafood is central—grilled fish, octopus, and shellfish are widely available at harbour-side tavernas. Mezedes (small shared dishes) are a good way to explore local flavours: expect tzatziki, taramasalata, grilled halloumi-style cheeses, stuffed vine leaves, and seasonal vegetables. Lamb and goat dishes are common inland.
Local specialities worth seeking out include pitaroudia (chickpea fritters, a Kos and Rhodes specialty), fresh grilled swordfish when in season, and the island's honey, which has a good local reputation.
Where to Eat
Kos Town has a wide range of restaurants from tourist-oriented establishments along the harbour to more local-feeling tavernas a few streets back. Kardamena is more resort-focused in character. For a quieter, more traditional meal, the villages in the interior—Pyli, Asfendiou, Zia—have small family-run tavernas, though hours and availability vary and calling ahead is sensible outside peak season.
Drinks
Greek coffee (filtered or 'ellinikos'), freddo espresso and cappuccino, and fresh orange juice are café staples. Local wine is available; Kos does not have a large wine-producing reputation compared to some other Aegean islands, but Greek wines from the mainland and other islands are widely poured. Ouzo and local spirits are standard taverna offerings.
Practical Information
Money
The currency is the Euro. ATMs are widely available in Kos Town and larger resorts. Card payment is accepted in most hotels and many restaurants and shops, though smaller tavernas and markets may be cash-preferred; carry some cash for these situations.
Connectivity
Mobile coverage is generally good in populated areas. EU visitors benefit from roaming rules that allow use of home-country allowances within Greece; non-EU visitors should check roaming charges with their provider or consider purchasing a local SIM. Wi-Fi is widely available in hotels, cafés, and restaurants.
Emergency Numbers
In Greece, the general emergency number is 112 (EU-wide). For police, 100; ambulance, 166; fire, 199. Kos has a general hospital (Kos General Hospital); for anything serious, verify its current location and contact information locally on arrival.
Electricity
Greece uses 230V/50Hz with Type C and F plugs (two round pins). Adaptors may be needed depending on your home country.
Tipping
Tipping is customary but not mandatory. Rounding up a bill or leaving small change in cafés and tavernas is appreciated; in restaurants a tip of around 5–10% for good service is common.
Safety
Kos is generally a safe destination for travellers. Petty theft—pickpocketing in crowded tourist areas and at the harbour—is the most commonly reported concern, particularly in high season. Standard precautions apply: keep valuables secure and be aware of your surroundings in busy market and nightlife areas.
Scooter and quad bike accidents are a recurring issue on the island, as they are across many Greek resort destinations. If hiring motorised two-wheelers, wear a helmet and ride cautiously, particularly on gravel roads or in areas unfamiliar to you. Check whether your travel insurance covers motorised vehicle accidents.
Sea conditions can change quickly, particularly on the south coast and around headlands. Observe local flags and advice at beaches, and be cautious of strong winds—Kos can experience the Meltemi wind in summer, which affects sea conditions.
Consult your government's travel advisory page for any current guidance before departure.
Local Culture & Etiquette
Kos shares the cultural norms of Greece broadly. Orthodox Christianity is central to local tradition; churches and monasteries are active places of worship, and modest dress (covered shoulders and knees) is expected when entering them.
The island's identity is closely tied to Hippocrates and the history of medicine—this is a point of genuine local pride rather than just a marketing angle. The Hippocrates Foundation organises cultural events, and the figure of Hippocrates appears widely in public art, street names, and civic life.
Due to its popularity with package tourists and proximity to Bodrum, parts of Kos Town and resort areas like Kardamena have a noticeably international character in summer. The local Greek character is more evident in the inland villages and during the shoulder and off seasons, when the island is quieter and local rhythms are easier to observe.
Greek meal times run later than northern European norms: lunch is typically from around 1:30 pm–3:30 pm; dinner rarely starts before 8:30–9 pm in local establishments. Many smaller businesses close during early afternoon.
