The Asklepion of Kos is one of the most important archaeological sites in Greece, a sacred healing center built on three terraces overlooking the Aegean where Hippocrates is believed to have taught and practiced medicine. Patients from across the ancient world traveled here seeking cures through a blend of medical treatment, thermal baths, and spiritual ritual. Wandering these atmospheric ruins with panoramic views stretching to the Turkish coast, you can feel why this place was considered a gateway between the human body and the divine. The Asklepion is the crown jewel among all the places to visit in Kos.
Nerantzia Castle stands guard at the entrance to Kos harbor, a formidable 14th-century fortress built by the Knights of St. John using stones recycled from the ancient Agora and other classical ruins. Its double ring of walls, connected by a bridge over a former moat, encloses a fascinating patchwork of Hellenistic columns, carved coats of arms, and Ottoman additions. Visitors who enjoy medieval fortifications will find a natural companion in the old town of Rhodes, the greatest stronghold the Knights ever built in the Dodecanese.
Kos Town preserves a rich layer of Ottoman heritage that adds depth and texture to the island's story. The Defterdar Mosque with its graceful minaret overlooks Eleftherias Square, while the Hadji Hassan Mosque near the ancient Agora stands as a quiet reminder of nearly four centuries of Ottoman rule. These well-maintained monuments sit comfortably alongside ancient Greek ruins and Italian-era buildings, making a stroll through Kos Town a journey through multiple civilizations in a single afternoon. See our Kos Island Guide for a suggested walking route through the town's historical layers.
The waters around Kos are dotted with smaller islands perfect for a day of exploration by boat. Pserimos, a tiny island with just a handful of residents, offers a pristine sandy beach and waterfront tavernas serving freshly grilled fish, while Nisyros — built inside a dormant volcanic crater — is one of the most dramatic landscapes in the Aegean. Daily excursion boats depart from Kos harbor throughout the summer season. If you are planning a wider island-hopping adventure, consider combining Kos with a ferry to Kastellorizo or a ferry to Samos for a truly memorable Aegean itinerary.

In the heart of Kos Town stands the legendary Plane Tree of Hippocrates, a massive ancient tree beneath which the father of medicine is said to have taught his students over two thousand years ago. While the current tree is estimated to be around 500 years old — likely a descendant of the original — its enormous canopy and gnarled trunk create an awe-inspiring atmosphere that draws visitors from around the world. A small stone bench and an Ottoman-era fountain sit beneath its shade, making it one of the most iconic spots on the island. Learn how to get to Kos and pay your own visit to this living monument to medical history.
The Roman Odeon of Kos, beautifully restored with its semicircular rows of marble seating, once hosted musical performances and public gatherings in the 2nd century AD. Just steps away, the sprawling Ancient Agora reveals the foundations of temples, stoas, and a Christian basilica layered one upon another across centuries. Together these sites form an open-air museum in the center of town that brings the classical world vividly to life. Archaeology lovers exploring the eastern Aegean will also enjoy the birthplace of Pythagoras on the island of Samos, another treasure of ancient Greek civilization.
Kos is blessed with some of the finest beaches in the Dodecanese, from the long golden sands of Tigaki and Marmari on the north coast to the sheltered turquoise cove of Paradise Beach in the south. For a truly unique experience, head to Therma Beach near Agios Fokas, where natural volcanic hot springs flow directly into the sea, creating a warm open-air spa surrounded by cool Aegean waters. It is the perfect place to unwind after a day of sightseeing — and proof that the island of Hippocrates still knows a thing or two about the healing power of water.

Perched on the green slopes of Mount Dikeos, the charming village of Zia is the most popular mountain retreat on Kos and famous across the Dodecanese for its spectacular sunsets. Narrow lanes wind past stone houses, artisan craft shops, and small tavernas serving traditional dishes made with local honey, herbs, and goat cheese. Arriving in the late afternoon to watch the sun sink behind the islands from Zia's hilltop viewpoint is an experience that captures the soul of Greek island life. Those who love picturesque villages may also be drawn to the mastiha villages of Chios, another Aegean island rich in traditional character.
No visit to Kos is complete without trying kolokytholoulouda gemista — stuffed zucchini flowers — a beloved Dodecanese delicacy that appears on taverna menus every summer. Delicate blossoms are filled with a mixture of local rice, fresh herbs, and soft cheese, then lightly fried or baked until golden and irresistible. This seasonal specialty embodies the island's farm-to-table spirit and is best enjoyed at a harbor-side table with a glass of chilled local wine.
