Town of Kos

The vibrant capital and main port of Kos island, is a captivating open-air museum where many layers of  history blends with modern Mediterranean charm. The imposing 14th-century Neratzia Castle, the town’s landscape is a unique tapestry of Hellenistic, Roman, Byzantine and Ottoman architecture, seamlessly integrate with recent Italian-era style and leafy palm-lined avenues. Visitors can wander through the cobblestone streets of the Old Town, visit the legendary Plane Tree of Hippocrates, or enjoy the bustling atmosphere of the harbor’s waterfront cafes. With its flat terrain making it bicycle friendly and its proximity to organized beaches, Town of Kos offers a perfect blend of cultural depth and modern island living.

Historical Sites

  • Neratzia Castle (Castle of the Knights) This 14th-century fortress stands guard at the entrance of the harbor. Built by the Knights of St. John, it features massive walls and bastions. Even if some interior sections are occasionally closed for restoration, the exterior and the stone bridge connecting it to the city are iconic photo spots.
  • The Ancient Agora Once the commercial and social heart of the city, this open-air archaeological site is free to enter. You can wander through the ruins of ancient temples (dedicated to Hercules and Aphrodite), columns, and early Christian basilicas.
  • Casa Romana A beautifully restored Roman mansion that gives you a glimpse into the luxury of the 2nd century AD. It features intricate floor mosaics, internal courtyards (atriums), and impressive frescoes.
  • Roman Odeon of Kos A remarkably well-preserved ancient theater from the 2nd century. It still has its original marble seats and underground galleries. It’s a peaceful spot, often used for cultural events during the summer.
  • Western Archaeological Zone Across from the Odeon, this area contains the ruins of the Ancient Gymnasium, the Nymphaeum, and some of the best-preserved floor mosaics in the city (look for the “Judgment of Paris”).

City Culture

  • Tree of Hippocrates Located right outside the Castle and the Agora, legend says Hippocrates taught his students under this plane tree. While the current tree is a “mere” 500 years old (a descendant of the original), its massive, hollowed trunk and the surrounding Ottoman fountains make it a central landmark.
  • Eleftherias Square (Freedom Square) The city’s main hub, surrounded by Italian-era buildings. Here you’ll find the Defterdar Mosque and the Municipal Market, where you can buy local honey, spices, and “gliko tou koutaliou” (spoon sweets).
  • Archaeological Museum of Kos Situated right on Eleftherias Square, this museum houses a stunning collection of Hellenistic and Roman statues, including a famous statue of Hippocrates and elaborate mosaics found in the city’s excavations.
  • The “White Stairs” For those looking for the perfect “Greek Island” aesthetic, this narrow, bougainvillea-lined alleyway in the Old Town is the most photographed street in the city.

Waterfront & Relaxation

  • Mandraki Harbor The picturesque waterfront is lined with palm trees and excursion boats. It’s the perfect place for a sunset stroll or to book a “3-Island Cruise” to nearby Kalymnos, Pserimos, and Plati.
  • Lambi Beach The closest high-quality beach to the city center. It’s a long, sandy stretch with plenty of beach bars and crystal-clear water, easily reachable by bike (Kos is famously the “island of the bicycle”).
  • Kos Marina A bit further down the coast from the main port, the marina is a modern area with great cafes and a more local, upscale vibe for evening drinks.
  • East Coast: Near Kos Town and Psalidi, the landscape becomes more pebbly and rugged, leading to the Empros Therme, a natural sea pool fed by hot volcanic springs.

Rest of Kos Island

Landscape & Nature

  • The Flatlands: Much of the island, particularly in the north and central regions, consists of low-lying, fertile plains. This flat profile makes it famously bike-friendly, earning it the nickname “The Island of Cyclists.”
  • The Mountain Spine: A mountain range dominates the southeastern coast. Mount Dikeos is the highest point at 2,780 ft. Its northern slopes are lush and forested, while the southern side falls away more steeply toward the sea.
  • The Peninsula: To the far west lies the Kefalos Peninsula, a more rugged and pristine area characterized by rocky hills and some of the island’s most secluded coastal scenery.
  • Lush Forests: You’ll find significant pine and cypress groves, particularly in the Plaka Forest near Antimachia (famous for its wild peacocks).
  • Agriculture: The landscape is dotted with olive groves, vineyards, and fields of figs and tomatoes.
  • Coastal Ecosystems: The island hosts vital wetlands like the Alyki Salt Lake (near Tigaki) and the Psalidi Wetlands. These are Natura 2000 protected sites where you can often spot flamingos and sea turtles.

Nature 

  • Therma (Hot Springs): On the eastern tip of the island, hot volcanic sulfur springs bubble up into a natural sea pool walled off by rocks. It’s like a free, natural spa—just be prepared for the “hardboiled egg” scent of the sulfur!
  • Plaka Forest: A cool, shaded pine forest near the airport that is famously inhabited by dozens of wild peacocks and a colony of friendly cats. It’s a surreal, peaceful spot for a picnic.
  • The Interior: Mount Dikeos (2,780 ft) offers hiking trails and the picturesque mountain village of Zia, famous for its sunset views.

Kos has some incredible rugged landscapes, ancient healing grounds, and “ghost” villages waiting for you, outside the city of Kos.

Scenic Villages

  • Zia: This is the highest village on the island and the place to be for sunset. While it can get touristy, the views from the slopes of Mount Dikaios are unbeatable. Grab a glass of kanelada (cinnamon drink) and wander the colorful craft shops.
  • Pyli: The “Pyli House” museum, a 6-pipe stone fountain, and the nearby ghost town of Paleo Pyli.
  • Asfendiou: Traditional stone houses, the church of Evangelistria, and a quiet, authentic vibe.
  • Agios Dimitrios:  Also known as Haihoutes, this is a semi-abandoned “ghost village.”
  • Kefalos Village: Perched on a cliff at the far west end of the island, the old village maintains a traditional feel far removed from the resort zones. Visit the traditional windmill and look down over the sweeping Kamari Bay.
  • Mastichari: A laid-back fishing village on the north coast. It’s the best place to find fresh seafood tavernas and catch a local ferry for a quick day trip to the sponge-diver island of Kalymnos.
  • Kefalos: Located at the far western tip. It is split between the traditional hilltop village and the seaside area of Kamari. It’s home to the famous Agios Stefanos beach, where you can swim out to a tiny islet with a blue-domed church.
  • Mastichari: A charming fishing village turned resort. It retains a laid-back feel and is the main port for ferries to the nearby island of Kalymnos. It’s famous for its fresh seafood tavernas.
  • Kardamena: The island’s primary nightlife hub. Once a simple fishing village, it is now packed with bars, clubs, and large hotel complexes.
  • Tigaki & Marmari: Located on the north coast, these are the “windy” resorts popular for windsurfing and long, flat, sandy beaches.

Historical & Ancient Sites

  • The Asklepieion: Located just a few kilometers outside the main town, this is the island’s crown jewel. It was an ancient medical center dedicated to the god of healing, Asclepius. Walking through the tiered terraces, you can almost hear the ghost of Hippocrates giving a lecture.
  • Paleo Pyli (Old Pyli): Often called the “Mystras of the Dodecanese,” this abandoned medieval village is tucked into the mountainside. Hike up to the ruined Byzantine castle for a view that stretches all the way to Turkey and the neighboring islands.
  • Antimachia Castle: A massive 14th-century Venetian fortress built by the Knights of St. John. It’s surprisingly well-preserved and offers a stark, windy atmosphere with panoramic views of the southern coastline.
  • Basilica of Agios Stefanos: Located right on the sand in Kefalos,  are the ruins of two 5th-century Christian churches. It’s one of the most photographed spots on the island, where the white pillars of the church ruins frame the tiny islet of Kastri, next to the turquoise sea. 

Beaches & Nature

With a coast line of 70 miles, Kos offers very  diverse beaches, ranging from volcanic black pebbles to soft golden sands:

  • Tigaki & Mastihari: Popular, well-organized sandy beaches on the northern coast, ideal for families and windsurfing.Known for long, sweeping stretches of fine white sand (Marmari, Tigaki, Mastichari) and shallow, turquoise waters.
  • Therma Beach: Known for its natural hot springs that flow into the sea, creating a warm, therapeutic “sea-pool.” Located on the eastern tip, this beach features natural hot volcanic springs that flow directly into a sea-walled pool, mixing with the cool seawater for a therapeutic soak.
  • Agios Stefanos: A picturesque spot where you can see the ruins of a 5th-century basilica right on the sand, with the tiny islet of Kastri just a short swim away.
  • Kefalos Beach: a stunning stretch of coastline renowned for its crystal-clear, refreshing waters right after Agios Steganos.
  • Agios Theologos Beach: If you want wild and rugged, head to the westernmost point. It’s not a “sunbed and umbrella” kind of place; it’s a spot for watching dramatic waves crash against the rocky shore during sunset.
  • Paradise Beach (and “Bubble Beach”): Famous for its fine sand and shallow water. If you swim near the shoreline, you’ll see tiny volcanic bubbles rising from the seabed, nature’s version of a jacuzzi.

Activities & Experiences

  • The “Bicycle Island”: Unlike many mountainous Greek islands, Kos is remarkably flat in the north and east. It features an extensive network of dedicated bike paths, making it the most bike-friendly island in Greece.

  • Zia Sunset: The mountain village of Zia is the highest inhabited point and is the go-to spot for watching the sunset over the neighboring islands and the Turkish coast.

  • Plaka Forest: A peaceful pine forest near the airport where hundreds of wild peacocks and cats roam freely.

  • Island Hopping & Day Trips: Its central location makes it a perfect base for day trips to Nisyros, where you can actually walk down into the steaming, sulfur-crusted crater of a dormant volcano. Bodrum, Turkey, is only a 20-minute boat ride away. Most boats leave from Kardamena or Kefalos.

  • Kitesurfing and Windsurfing: Kohilari Beach, located on the island’s northern shore near Kefalos, is a premier destination for these sports.

  • Hiking:  most exciting trail starts from the village of Zia,  it is a well-marked and takes about 1.5 to 2 hours to reach the summit of Mount Dikeos.
