Marmari is the long, open, dune backed beach on the north coast of Kos, and it works best when you match it to the hour. This is not a tight postcard cove but a broad sandy sweep several kilometres long, low natural dunes behind it and a modest resort strip set back from the water. The pleasure is space and an easy sandy entry that shelves gently into shallow water, so on a still morning it is one of the more relaxed swimming and paddling beaches on this side of the island, with room to spread out well away from the next towel.
The character changes with the wind, and that is the honest key to the place. Marmari sits where the breeze funnels down between the islands to the north, so it catches a reliable summer meltemi that tends to build through the afternoon. For swimmers that means the calm window is often the morning, before the chop comes up, while for windsurfers and kitesurfers the same wind is the whole point, and the Marmari Windsurfing Center on the shore runs lessons and rents boards and stand up paddle gear for it. Read the beach as a morning swim and an afternoon sail and it rarely lets you down.
The notes to keep in mind are about exposure. Because it is long and open, cover is patchy, so bring shade if you want a quiet stretch away from the organised sunbeds, and be ready for the wind to strengthen and cool the water later in the day. There is no lifeguard along the whole beach, the shallow chop can nudge you down the shore, and the sunbed sections fill in high summer, so come early for the calm and the space. Use reef safe products, mind the wind with children and inflatables, and take your rubbish back out.
Come to Marmari for the long sands, the gentle entry and the wind, then vary your Kos days. For another shallow family beach along this coast go to Tigaki Beach, for the harbour village stretch with the boats try Mastichari Beach, and for the lively volcanic hot spring shore see Paradise Beach.

Sunbeds, tavernas and a windsurf centre
Marmari is a long public beach rather than a single built club, so the service is spread along the organised sections. Those have sunbeds and umbrellas to rent, with tavernas and beach bars behind the sand, and the Marmari Windsurfing Center runs lessons and rents boards and stand up paddle gear on the shore. For a wider choice of loungers and beachfront venues across the island, use the Kos beach clubs directory.

The service here is a rented sunbed and a taverna lunch in the organised sections, plus a windsurf and stand up paddle centre for the afternoon breeze, rather than one gated beach club. Take a serviced spot for shade and drinks, or walk along to open dune backed sand for quiet, and treat the wind as the beach's main event once it builds.

Marmari Beach, Kos
Marmari is on the north coast of Kos, between Tigaki and Mastichari and a drive of roughly fifteen minutes from Kos Town. It is served by the island buses and easy to reach by car, with parking near the organised sections, and the long shore has several access points so you can pick a serviced stretch or walk to a quieter one. A hired car or scooter gives you the most freedom to move along the coast.
Because the beach is long and open, bring shade and water if you want a quiet natural stretch, and be ready for the wind to build and cool the sea through the afternoon. Come in the morning for the calmest swimming, use reef safe products, mind children and inflatables when the meltemi is up, swim within your depth as there is no lifeguard along the whole beach, and take your rubbish back out. Conditions are typical rather than guaranteed.

Marmari Beach FAQ
How do you get to Marmari Beach in Kos?
By road along the north coast of Kos. Marmari sits between Tigaki and Mastichari, a drive of roughly fifteen minutes from Kos Town, and it is served by the island buses as well as by car, with parking near the organised sections. The long shore has several access points, so you can pick a busier serviced stretch or walk along to a quieter patch of dune backed sand.
Is Marmari Beach good for swimming?
Yes, on calm days it is one of the friendlier north coast beaches for it. The entry is sandy and shelves gently, so it suits easy swimming, paddling and families when the sea is still. The same coast catches the summer meltemi wind, though, so on breezy afternoons the water turns choppy and cooler, which is why the windsurfers arrive. Read the wind, and swim within your depth as cover is limited.
Is Marmari Beach good for windsurfing?
Yes, it is one of the better spots on Kos for it. The bay sits where wind funnels between the islands to the north, so it picks up a reliable summer breeze, and the Marmari Windsurfing Center on the shore runs lessons and rents boards and stand up paddle gear. Mornings are often calmer for swimming, with the wind building through the afternoon for riders.
Are there sunbeds and tavernas at Marmari Beach?
Yes, in the organised sections. Parts of the long beach have sunbeds and umbrellas to rent along with tavernas and beach bars behind the sand, while the stretches between them stay natural and open. That mix lets you choose a serviced day or a quiet towel on the dunes, so walk a little to find the balance you want.
When is the best time to visit Marmari Beach?
From May to October, with July and August warmest and busiest. If you want calm water for swimming, come in the morning before the meltemi builds, or visit in the shoulder months of May, June, September and October when the wind is often lighter and the beach quieter.
