The island of Hippocrates — beaches, bikes and ancient healing
Weed in Kos: the law, the CBD shops, and how the medical route works
Kos wears its history lightly: the sanctuary where Hippocrates taught medicine overlooks a modern island of long sandy beaches, flat cycle paths, hot springs and lively resort towns. It's also a place where visitors increasingly ask about cannabis laws — so this guide answers that clearly, alongside everything else worth knowing.
Why Visit Kos
Kos blends easy beach holidays with real history and a layout that's unusually simple to explore. It suits almost every kind of traveller.
The Birthplace of Modern Medicine
The Asklepion — a terraced healing sanctuary just outside Kos Town — is where Hippocrates practised and taught. Few places connect ancient and modern wellness so directly.
Flat, Bike-Friendly and Compact
Kos is one of the few Greek islands with proper cycle paths. Kos Town and the northern beach resorts are genuinely explorable by bike.
Long Sandy Beaches
From Tigaki and Marmari in the north to the sweeping Kefalos Bay in the southwest, Kos has some of the Dodecanese's best sand — much of it shallow and family-friendly.
Natural Hot Springs
At Therma, near Agios Fokas, hot mineral water pours into a rock pool right on the beach — a natural spa session with the Aegean lapping beside you.
Easy Day Trips
The volcanic island of Nisyros, with its walkable caldera, is a short boat ride away, and Bodrum in Turkey is visible across the strait with regular ferry connections.
Best Things to Do in Kos
Kos rewards a mix of lazy beach days and short, easy excursions — nothing on the island is far away.
The Asklepion
The island's headline site: three terraces of temples and treatment halls where medicine was taught in antiquity, with cypress-framed views back to Kos Town and the Turkish coast.
Tip: Go early or late in the day — there's little shade — and combine it with the plane tree of Hippocrates in town.
Kos Town Old Quarter
Neratzia Castle guards the harbour, the ancient agora sprawls beside the main square, and Ottoman mosques and Italian-era buildings mix along streets draped in bougainvillea.
Therma Hot Springs
A natural thermal pool where volcanically heated spring water meets the sea. Best in the shoulder months when the contrast is at its most pleasant.
Tip: Water shoes help — the entry is over pebbles.
Nisyros Volcano Day Trip
Boats from Kardamena and Kos Town cross to Nisyros, where you can walk on the floor of the Stefanos crater — one of Greece's most accessible volcanic landscapes.
Zia Village at Sunset
A mountain village on the slopes of Mount Dikeos famous for its sunset views across the island and the Aegean. Touristy, but for good reason.
Kefalos Bay & Kastri Islet
The island's most photogenic swim: a long curve of sand facing the tiny chapel-topped Kastri islet, which confident swimmers can reach from Agios Stefanos beach.
Cycle the North Coast
Flat, dedicated paths link Kos Town with Lambi, Tigaki and Marmari — hire a bike and beach-hop the way locals do.

Where to Stay in Kos
Kos's resorts are spread around the coast, each with a clear character — and distances are short enough that no choice locks you in.
Kos Town
The all-rounder: harbour restaurants, history on every corner, nightlife and bike access to nearby beaches. Best base without a car.
€50–€140/nightKardamena
The party resort, long popular with young British visitors — bars, clubs and a big sandy beach, plus the Nisyros boats.
€45–€120/nightTigaki & Marmari
Quieter northern beach resorts with long shallow sands — a family favourite within cycling distance of town.
€50–€130/nightKefalos & Agios Stefanos
The scenic southwest: a huge sheltered bay, relaxed pace and the island's prettiest views. Further from the airport buzz.
€55–€150/nightWhere to Eat in Kos
Kos cooking is Dodecanese comfort food — local cheeses, slow bakes and seafood — with the best value found away from the harbourfront.
Kos Town Side Streets
A block or two behind the harbour, family tavernas serve grilled fish, stuffed vegetables and local wine at everyday prices.
Kos TownZia's Sunset Tavernas
The mountain village pairs its famous views with tavernas grilling over charcoal — book a terrace table before sunset in summer.
ZiaKefalos Fish Tavernas
The fishing-village end of Kefalos Bay keeps a working-harbour feel, with the day's catch driving the menu.
KefalosLocal Specialities
Try krasotyri — the island's wine-washed cheese, also called posa — along with pitaridia (handmade pasta), local honey and sweet tomato preserves.
Island-wideBest Time to Visit Kos
Kos runs on a classic Aegean season — May to October — with the meltemi breeze taking the edge off midsummer heat on the north coast.
Late Spring (May–June)
Warm, green and open for business without peak crowds. Sea temperatures become properly swimmable by June.
Summer (July–August)
Hot, busy and breezy — the meltemi wind keeps the north coast fresher than the sheltered south. Peak prices in the resorts.
Early Autumn (September–October)
The best all-round window: warm seas, softer light, and space on the beaches. The hot springs at Therma feel even better as the air cools.
Winter (November–April)
Charter flights stop and resorts largely close; Kos Town stays pleasantly alive as a local island capital reachable via Athens or Rhodes.
Getting Around Kos
Kos is one of the easiest Greek islands to get around — flat in the north, compact overall, and well served by buses in season.
Bicycle
The island's signature transport. Dedicated paths run along the north coast, hire is cheap, and Kos Town to Tigaki is an easy, flat ride.
Hire Car or Scooter
Needed for Zia, Kefalos and the southwest beaches. Roads are good and distances short — the whole island is under an hour's drive.
KTEL Buses
Seasonal routes link Kos Town with Tigaki, Marmari, Kardamena, Kefalos and Zia — more useful here than on most islands, but check evening return times.
Boats & Ferries
Day boats run to Nisyros, Kalymnos and Pserimos, and ferries connect to Bodrum (Turkey), Rhodes and the wider Dodecanese from Kos Town harbour.

Practical Tips for Kos
- Kos International Airport 'Hippocrates' (KGS) sits mid-island — around 25 minutes from both Kos Town and Kefalos, with seasonal direct flights from most UK and German airports.
- The 'cannabis shops' you'll see in Kos Town and the resorts sell legal CBD and low-THC hemp products — they are not dispensaries and cannot sell medical cannabis.
- Recreational cannabis is illegal throughout Greece, including Kos — possession is a criminal offence.
- Crossing to Bodrum for a day trip means leaving the EU — carry your passport and check visa requirements for your nationality.
- The meltemi wind can be strong in July and August — north-coast watersports thrive, but pack a light layer for evenings.
- Book Nisyros boats a day ahead in peak season; morning departures give the most crater time.
- Pharmacies are plentiful in Kos Town and the larger resorts — Greece dispenses prescribed medication, including medical cannabis products, through pharmacies only.
