12 Underrated Places to Visit in Kos, Greece

Kos makes a beach holiday wonderfully easy. There are sandy bays, waterfront tavernas and enough sunshine to make an afternoon swim feel like the most sensible thing on your itinerary.

But venture beyond the familiar resort routes and the island becomes more varied. Medieval settlements cling to rocky hillsides, peacocks wander through pine forests, and ancient churches stand just metres from the sea. Even the landscape changes: the gentle northern coastline gives way to mountain paths and exposed headlands around Kefalos.

These 12 places reveal a different side of Kos. Some are genuinely overlooked; others are familiar names that deserve more than a quick photograph or a visit at the busiest time of day.

1. Palio Pyli: A Medieval Village Above the Island

Also known as Palea Pyli or Old Pyli, this abandoned settlement is one of the most atmospheric historical sites on Kos.

Stone walls, ruined houses and old churches are scattered across a wooded hillside beneath a castle. As you follow the uneven paths, the village gradually reveals itself: a doorway here, a stretch of old paving there, another building almost absorbed by the vegetation.

The castle has Byzantine origins and was later repaired by the Knights Hospitaller. From its elevated position, the views reach towards the northern coast and, on clear days, neighbouring islands.

Give yourself time to explore the settlement as well as the upper ruins. The climb is part of the experience, but the terrain requires proper footwear.

Plan your visit: Go early or in the cooler part of the afternoon, carry water and leave enough daylight for the descent.

2. Cavo Paradiso: A Beach at the End of the Road

Cavo Paradiso feels far removed from the island’s organised resort beaches. On the remote southwestern edge of the Kefalos peninsula, pale sand meets open sea beneath steep, rugged hills.

Getting there takes some planning. The approach includes an unpaved road, and its condition can make the journey considerably slower than the distance suggests.

Once you arrive, the appeal is obvious: a broad shoreline, turquoise water and a landscape with very little to distract from the sea. Limited seasonal facilities may be available, but it is sensible to bring your own essentials.

The exposed location also means wind and waves can change the character of the beach. Choose a calm day if swimming is your priority.

Plan your visit: Check the access route and your car hire agreement before driving onto an unpaved road. Cavo Paradiso is a different beach from the better-known Paradise Beach near Kefalos.

3. Plaka Forest: Pine Trees and Free-Roaming Peacocks

A short detour near Antimachia brings you into Plaka Forest, where the shade offers a welcome change from the bright, open coastline.

Peacocks roam freely beneath the pines, sharing the woodland with a resident population of cats. Their presence makes this an especially enjoyable stop for families, although the forest works just as well as a quiet break between sightseeing visits.

There is no need for a complicated itinerary. Wander the shaded paths, pause on a bench and watch the birds moving between the trees.

Plaka is particularly appealing on a warm day, when a little time away from the beach can be surprisingly refreshing.

Plan your visit: Give the animals space, avoid chasing them for photographs and take any picnic rubbish away with you.

4. Antimachia Castle: A Fortress Worth Taking Your Time Over

Antimachia Castle makes an impression before you even enter. Its substantial walls rise above a plateau, with views towards the southern coast.

Built by the Knights Hospitaller during the medieval period and strengthened over time, the fortress once sheltered a settlement within its defences.

Inside, the open space helps you appreciate its scale. Ruined buildings, cisterns and the churches of Agios Nikolaos and Agia Paraskevi survive among the remains.

This is a place to explore slowly, looking at how the fortifications follow the terrain and imagining the community that once lived behind them.

Plan your visit: Bring sun protection and water. Much of the site is exposed, and you should stay clear of unstable masonry and unprotected edges.

5. Agios Theologos: A Sunset Stop on the Wilder Coast

Beyond Kefalos, Agios Theologos offers a more rugged coastal scene: shingle, rocky coves and waves rolling in from the open Aegean.

It is an excellent place to end a day exploring the western part of Kos. Arrive while there is still plenty of light, take a walk along the shore and settle in as the colours begin to change.

The seaside taverna adds another reason to linger when it is open. A leisurely meal here can be a lovely way to watch the sunset without rushing straight back to your hotel.

On windy days, the sea becomes the main spectacle. Swimming is best considered according to the conditions rather than treated as an essential part of the visit.

Plan your visit: Check seasonal opening times if you are planning dinner, and bring a light layer for the evening breeze.

6. Alykes Salt Lake: A Different Side of Tigaki

Between Tigaki and Marmari, Alykes introduces a quieter landscape of salt flats, reeds and wetland habitat.

Once used for salt production, the area now provides shelter for resident and migratory birds. Flamingos are among its best-known visitors, although sightings depend on the season, water levels and migration patterns.

The wetland can look dramatically different throughout the year. Following rainfall, water brings more birdwatching opportunities; in summer, much of the landscape may be dry.

A slow walk around the accessible edges offers a welcome contrast to a day on the nearby beaches. Bring binoculars if you have them, and allow yourself time to observe rather than simply pass through.

Plan your visit: Keep to existing paths and observe birds from a distance. Flamingos are a possible highlight, rather than a guaranteed attraction.

7. Agios Ioannis Thymianos: A Peaceful Detour Near Kefalos

In the hills south of Kefalos, Agios Ioannis Thymianos is a small monastery site with a white-and-blue church, a shaded courtyard and views towards the sea.

A large plane tree provides a natural place to pause. Beyond the grounds, the surrounding hills give this corner of Kos an open, rural feel.

The attraction is its modest scale. Spend a little time looking at the church, enjoying the view and appreciating the setting before continuing your journey.

It makes a rewarding addition to a day around the Kefalos peninsula, particularly if you enjoy small religious sites and scenic drives.

Plan your visit: Dress respectfully and keep noise low. Access to the church interior may vary, so approach the visit as a chance to enjoy the setting rather than a guaranteed tour.

8. Asfendiou: Traditional Lanes Beyond Zia

Zia draws plenty of visitors for its views and sunsets, but the nearby traditional neighbourhoods of Asfendiou deserve attention too.

On the slopes of Mount Dikaios, the old areas of Evangelistria and Asomatos retain stone houses, narrow lanes and historic village architecture.

Explore on foot and look at the details: the proportions of an old doorway, a church tucked into the neighbourhood, the way buildings fit into the hillside. These are places best appreciated at walking pace.

Asfendiou is still a living community, even where older buildings stand empty. Its appeal lies in the chance to see a different rhythm of island life.

Plan your visit: Combine it with Zia, but leave time for a separate wander. Respect private homes and park without blocking the village lanes.

9. Agios Stefanos: Ancient Basilicas Beside the Beach

Agios Stefanos is hardly unknown, yet its archaeological remains can be overshadowed by the famous view across the water.

Beside the beach stand the remains of two early Christian basilicas dating from the fifth and sixth centuries. Columns, foundations and surviving mosaic sections reveal the layout of buildings that once occupied this remarkable seaside position.

Offshore, the little island of Kastri and its chapel complete the scene.

Take a few minutes to look beyond the postcard composition. Following the outlines of the basilicas gives the beach a historical dimension that is easy to miss during a swimming stop.

Plan your visit: An early visit offers softer light and often a calmer atmosphere. Respect barriers and avoid stepping on mosaics or climbing the remains.

10. Therma Beach: Hot Springs with a Sea View

On the southeastern coast, Therma — also known as Empros Therma — combines a rocky beach with natural hot springs.

Thermal water flows into the sea, where stones form a bathing area in which warmer spring water mixes with cooler seawater. The temperature varies within the pool, so there is no single temperature that describes the whole experience.

The setting is striking: dark stones, steep slopes and open sea. The sulphurous smell is another reminder that this is a natural spring rather than a conventional spa.

Therma is a popular attraction, but visiting early can give you a better chance of enjoying it without the busiest daytime crowds.

Plan your visit: Expect a downhill walk and an uphill return. Enter the water gradually, avoid the hottest inflow and check the sea conditions before bathing.

11. Mount Dikaios: Kos from Its Highest Point

For a complete change of perspective, head into the mountains.

Mount Dikaios, also written as Dikeos, reaches 846 metres and is the highest point on Kos. A hiking route from Zia climbs towards a summit marked by a cross and a small chapel dedicated to Christ.

On a clear day, the views stretch across the island and towards the surrounding Aegean islands.

The walk deserves its own place in your itinerary. Rocky ground, sustained uphill sections and exposure to the weather make it a proper hike rather than an extension of a stroll around Zia.

Plan your visit: Start early, carry sufficient water, wear walking shoes and take an offline map. Choose suitable weather and allow plenty of time to return before dark.

12. The Tomb of Harmylos: A Small Site with a Long History

In modern Pyli, the Tomb of Harmylos offers a quieter encounter with the island’s ancient past.

Known as the Harmylion, this Hellenistic funerary monument dates to the third century BC and is associated with the Harmylos family. The Church of the Holy Cross was later built above it.

The site has a very different scale from a sprawling archaeological complex. Its interest comes from the layers of history preserved in one place, where an ancient burial monument and a later church occupy the same location.

Combine the visit with a walk through Pyli and a stop in the village square. It is a good reminder that worthwhile discoveries on Kos do not always require a long excursion.

Plan your visit: Check local access arrangements if you want to see inside. Modern Pyli and the abandoned settlement of Palio Pyli are separate places.

How to Fit These Places into Your Kos Holiday

Spread these visits across a few days rather than trying to cover the entire island in one outing.

For medieval history and village life, combine Palio Pyli, modern Pyli and Asfendiou. Add Zia if you have time, but keep the Mount Dikaios hike for a separate morning.

For a day around Kefalos, choose Agios Stefanos, Agios Ioannis Thymianos and an evening at Agios Theologos. Give Cavo Paradiso its own generous time slot, especially if you plan to spend several hours on the beach.

For an easy inland excursion, pair Antimachia Castle with Plaka Forest.

For nature, visit Alykes when water levels and migration conditions are favourable, or plan a morning hike on Mount Dikaios.

A hire car gives you flexibility for many of these stops. For remote routes, check road conditions and rental restrictions before setting off. An SUV does not automatically mean that unpaved-road driving is permitted.

Make Room for a Different Kos

A beach holiday and a more adventurous visit fit comfortably into the same trip.

You might spend one morning among the ruins of an abandoned village, another watching birds at a salt lake, and an evening beside the waves on the Kefalos coast. There is still plenty of time left for swimming and a long lunch.

At Only Blue, we think those small changes of scene are often what make a holiday memorable. Choose a few places that interest you, leave room to linger and discover how much Kos has to offer beyond its familiar beaches.
