Kos in 5 Days: Beaches, Villages and What We Actually Thought

Five days on Kos gave us time to explore beyond the beach near our hotel. We stayed in Marmari and visited Mastihari, Kos Town, Zia, Kardamaina and the beaches around the isdland. Each outing felt a little different, and this itinerary follows the route we actually took in September 2026, including the places we enjoyed and the ones we would skip next time.

☀️ When to Visit Kos

For beach and swimming, late June through September is the best window. July and August bring the hottest days and warm sea, but they are also the peak holiday months. June is a good choice if you want plenty of sunshine for exploring as well as beach time, though the water can still feel cool early in the month.

September is my pick for the best balance. The sea has had all summer to warm up, and the days are usually still hot enough for the beach. We visited in September 2026 and saw plenty of tour buses, yet the island did not feel overwhelmingly busy to us. Typical sea temperatures are around 24–25°C at that time of year.

October can still be warm enough to swim, especially earlier in the month, but beach weather becomes less dependable. The sea averages around 22–23°C, while the air cools and rain becomes more likely. May is better suited to sightseeing and exploring than to a trip built around long swims.

If spending hours in the water is your priority, I would choose July, August or September.

✈️ How to Get to Kos

Kos International Airport (KGS) has more connections than you might expect from a Greek island. Flying Aegean Airlines via Athens is one option, but seasonal direct flights also link Kos with cities in Germany, Italy, Switzerland, the UK and elsewhere in Europe. One of my favourite sites for checking the possibilities is the FlightConnections map for Kos.

🚗 How to Get Around Kos

A car is the easiest way to follow this itinerary. It lets you combine places such as Zia and Kardamaina and change beaches if the wind or waves are not what you hoped for. We rented one during our trip, and that flexibility was especially useful during our stay.

Kos is possible without a car, but I would stay in Kos Town if you plan to rely on buses. KTEL lists routes from town to Marmari, Mastihari, Zia, Kardamaina and Kefalos. Check the return timetable before leaving for a beach, as services change. The airport also has direct buses to several destinations, so you do not necessarily have to travel through Kos Town on arrival.

🏨 Where We Stayed: Hotel Esperia, Marmari

We stayed at Hotel Esperia in Marmari on a half-board deal, and it was great value for our trip. Breakfast had a large selection. Dinner varied each evening, usually with vegetarian options, chicken or turkey, pork and beef, and something from the local cuisine.

We also really enjoyed the pool and the beach was less than a ten-minute walk for us, so it was easy to spend time there between outings. Marmari worked well as a beach base with a car; if you are travelling mainly by bus, I would compare hotels in Kos Town first.

🗺️ Our Five Days in Kos

Day 1: Arrival and Mastihari

We kept our first day close to our base and went to Mastihari. It is a cute little village with a broad sandy beachfront, places to eat and a port for ferries to Kalymnos. It was an easy way to start the trip without planning a long drive immediately after arriving.

The beach beside the centre had a lot of seaweed when we visited. However, the sunbeds were good value: we paid €12 for the first row and €10 for the rows behind in September 2026.

Day 2: Kos Town and Marmari Beach

We spent the morning exploring Kos Town. I had expected more white houses, perhaps because I had the Cyclades in mind. It was still nice to walk around, with plenty of restaurants where you could sit outside, but it has a different vibe from Paros.

We then tried Psalidi Beach. It was windy and did not appeal to us, so I would not recommend making it your main beach stop based on our visit. We went back towards our hotel and spent time at Marmari Beach instead. There, we found a mix of paid sunbeds and places offering beds when you ordered something, without a minimum spend at the spots we checked. Ask each beach bar about its terms before sitting down.

Day 3: Magic Beach

For a quieter beach day, we drove towards Kefalos and stopped at Magic Beach, also known as Polemi or Exotic Beach. We had heard it was the best bay on Kos, and it lived up to that recommendation. It felt peaceful and a little remote, and we were happy to spend the afternoon there. Sunbeds cost us €15 in first row.

The different names used for this stretch can be confusing, so check the exact location before driving out. Some parts of the wider beach are described as naturist areas, which is also worth knowing when choosing where to settle.

Day 4: Zia and Kardamaina

In the morning qw visited Zia, a lovely little village with amazing views. It could be a particularly nice place to plan sunset and dinner.

Kardamaina was much busier, with lots of tourists and a shopping street. Its town beach was less windy as usual. The cheapest sunbeds we found without a required purchase were €15 outside the first row. Several other places had a minimum consumption requirement, so ask around rather than taking the first available beds.

Day 5: Agios Stefanos Beach and Petra Marinou Winery

We spent another day in the bay at Agios Stefanos Beach, one of the most memorable settings of our trip. There are ruins beside the beach and a little church on the island of Kastri, which you can swim towards easily.

Much of the beachfront appeared to belong to a luxury hotel, with a smaller area of public sunbeds. It was €20 for the first row and €15 for the others. It felt thw quietest in terms of wind and waves than several other beaches we tried, although we also noticed more children here. The ruins and view towards the little island make it worth visiting even if you do not plan a full day on a lounger.

We also visited Petra Marinou Winery for a wine tasting. The setting was lovely, and we really enjoyed the wines. You can buy bottles there too, so it is worth leaving a little room in your suitcase if you find a favourite. Our tasting cost €18, which I’ve included in the trip budget below.

⛴️ If You Have More Than Five Days in Kos

Take a Day Trip to Bodrum, Turkey

From Kos, you can see the Turkish coast across the water, and Bodrum is close enough for a day trip. Ferries leave from Kos Town, so you can stay at your hotel on Kos and spend a few hours exploring Bodrum’s harbour and centre, having lunch or visiting the castle. We did not make the crossing ourselves, but it would be my first choice for an extra day away from the beaches. If you are travelling without a car, compare ferry tickets with organised trips that include a transfer from your hotel.

Greek Island Day Trips from Kos

If you would rather spend your extra day on another Greek island, Kalymnos is the simplest independent trip. Ferries leave from Mastihari and take around 30 minutes to reach Kalymnos; check the ANEM Ferries timetable before choosing your day.

For something different, head to Nisyros to explore its volcanic landscape and the harbour village of Mandraki. There are scheduled ferries between Kos Town and Nisyros, but check both directions carefully before planning a same-day return.

🤿 Diving in Kos

If you would like an activity beyond beach days, you can look at introductory scuba trips and dive boat excursions from Kos, including trips around nearby Pserimos. Unfortunately, we only had five days on Kos, so I did not have time to dive.

These are my recorded costs from September 2026 for six nights per person.
