Dodecanese
Kos
A first trip to Kos for UK travellers: which resort to base in, the flat island you can cycle end to end, real airport-transfer and daily costs, and whether the package deal is the smart buy.
In short
Kos at a glance
Kos is the easy Greek island: a 4–4.5 hour direct charter from most UK airports, a 27km strip of mostly flat land you can genuinely cycle from town to beach, and a castle-and-ruins old town that gives you more history than the average package island. Most people buy it as a TUI or Jet2 package and stay put in one resort. That works — but knowing which of the four main bases suits you (and that the island is small enough to mix them) is what separates a good week from a bored one.
Kos is the Greek island the charter machine was built for: a flat 27km strip in the Dodecanese with a long-haul history (this is Hippocrates’ island), beaches on every coast, and direct flights of around four hours from most UK airports. TUI and Jet2 sell it hard as a package, and for a lot of people that’s the right call — fly, transfer, drop into one resort, repeat for a week. The trap is treating the four main bases as interchangeable. Kos Town gives you castle ruins, ferries and the widest choice of tavernas; Tigaki is the flat-beach family pick; Kardamena is the nightlife strip; and Kefalos, out at the south-west tip, has the best beach and the quietest week. Pick wrong for your group and you’ll spend the holiday on the bus.
What sets Kos apart from the steeper Greek islands is how easy it is to move under your own steam. The land is genuinely flat, there’s a seafront cycle path running out of Kos Town in both directions, and a hire bike costs a few pounds a day — so you can mix a beach resort with the history without renting a car. The big-ticket sight is the Asklepion, the terraced ancient healing sanctuary a short ride above town, which costs €8 and rewards you with a view straight across to Turkey. The harbour-side Castle of the Knights of Saint John is free to admire from outside, though its interior has been closed since the 2017 earthquake.
The smart move on Kos is to lean on its position. Bodrum in Turkey is a 20–45 minute ferry from Kos Town harbour — leave around nine, back by five, passport in pocket — and gives you a complete change of scene for a day. The volcano island of Nisyros makes another easy hop. Go in May, June, September or early October and you’ll get 25–28°C days, a warm sea and resorts that aren’t yet at full July–August roar. The statutory entry, health and safety facts for Greece are covered on the Greece country guide; Kos itself asks little more of you than choosing the right base and a sun hat.
The route
A relaxed week built around one base with day trips, rather than constant moving — Kos is small (about 27km long) so you can reach most of it on a hire bike, a scooter or the cheap KTEL bus. This assumes you've based in or near Kos Town; adjust the order if you're down in Kefalos.

Days 1–2
Kos Town
Settle in and do the history on foot: the harbour-side Castle of the Knights (free, viewed from outside since the 2017 earthquake closed the interior), the ancient agora ruins scattered through the centre, and the much-photographed Plane Tree of Hippocrates. Hire a bike on day two and ride the flat seafront path east towards Psalidi.
-
Day 3
Asklepion & inland
Cycle or bus the 4km up to the Asklepion (€8), the ancient medical sanctuary tied to Hippocrates — the terraced ruins and the view back over the town to Turkey are the real draw. Afternoon at Tigaki's long, shallow, child-safe beach, 12km west.
-
Day 4
Bodrum, Turkey
Take the morning ferry from Kos Town harbour to Bodrum (20–45 min, leaves around 09:00, back 16:00–17:00) for a day in Turkey — the castle, the bazaar and a completely different feel. Bring your passport; it's a border crossing, not a beach hop.
-
Days 5–6
Kefalos & the south
Head to the south-west tip: Kamari Bay below Kefalos village has the island's best stretch of golden sand and turquoise water, plus the offshore Kastri islet chapel. Paradise Beach nearby is busier and better for facilities. A hire car or scooter earns its keep here.
-
Day 7
Slow last day
A final beach morning, last swim and a long taverna lunch — gyros and a Mythos for under £8 — before the transfer back. Kos Town's waterfront is the easy choice if you've a late flight.
Where to base yourself
Pick one or two bases rather than moving every night.
Kos Town
££ mid-rangeThe best all-round first base: the castle, the ancient agora and the harbour ferries are on your doorstep, the seafront cycle path starts here, and it has the island's widest choice of tavernas and bars. The beaches either side are pebbly-to-coarse rather than soft sand — fine for a dip, not a desert-island week.
Best for: History, nightlife, ferries, no car needed
Tigaki
££ mid-rangeA flat, low-key resort 12km west with a 3km+ shallow golden-sand beach that's about as child-safe as Greek beaches get. The salt-lake flamingos behind it and the dead-flat roads make it the cycling and family pick. Quiet in the evenings — that's the point.
Best for: Families, calm beaches, cycling
Kardamena
£ valueThe package island's liveliest resort and its main nightlife hub — a former fishing village turned bar-and-club strip on the south coast, closest to the airport. Tamer than its old reputation but still where the young-crowd charter deals land. Avoid if you want quiet.
Best for: Nightlife, lively package crowd, value
Kefalos (Kamari Bay)
££ mid-rangeThe south-west tip, 40km from town, with the island's prettiest beach — golden sand, clear water and the Kastri chapel islet offshore. A traditional hilltop village above a resort strip. Far from everything, so a hire car or scooter is close to essential, but it's the quietest, most scenic base.
Best for: Best beach, scenery, couples, quiet
Getting around Kos
Kos is flat and small, which makes it one of the easiest Greek islands to get around without a car. A hire bike costs a few pounds a day and there's a long seafront cycle path running out of Kos Town in both directions. The KTEL bus network links the airport, Kos Town and the main resorts cheaply (airport–town is €3.50) but runs only a handful of times a day, so check the timetable. A scooter or quad is the popular choice for reaching the south, and a hire car earns its keep only if you're based in Kefalos or want the whole island in one trip. Taxis are metered but limited in number — book ahead in peak season.
