How many days in Kos? 4 days of beaches, the Asklepion and island hopping
By Tony Panopoulos · travel-agency planner in Greece · Updated
Kos is the third-largest island of the Dodecanese, close to the Turkish coast, and the birthplace of Hippocrates, the father of medicine. It combines long sandy beaches, flat cycling paths, ancient ruins in the middle of the town, and the mountain villages of Mount Dikeos. Four days covers Kos Town with its Roman ruins and Knights' castle, the Asklepion, the villages and sunset at Zia, the beaches of the south around Kefalos, and a boat trip to the volcano of Nisyros.
Short answer
Three days covers Kos Town, the Asklepion, Zia and the south's beaches. The fourth day goes to the Nisyros volcano.
The 4-day plan, day by day
Day 1: Kos Town
Morning. See the Tree of Hippocrates, a huge plane tree said to stand where Hippocrates taught (the tree itself is about 500 years old), and the Castle of the Knights of St John (Neratzia) at the harbour. Walk through the Ancient Agora, ruins in the middle of town.
Afternoon. Visit the Western Archaeological Site with Roman mosaics and the Casa Romana, a restored Roman villa with mosaics and courtyards, and the Archaeological Museum with a statue of Hippocrates.
Evening. Cycle or walk along the waterfront and have dinner in the old town lanes.
Kos Town has many bike lanes; rent a bike to get around.
Day 2: The Asklepion and Zia
Morning. Visit the Asklepion (about €8-10), 4 km from town, a healing sanctuary dedicated to Asclepius, where Hippocrates is said to have trained. It rises on three terraces with views to the Turkish coast.
Afternoon. Relax at the hot springs of Therma (Empros Therme), where hot water flows into the sea in a pool of rocks, then drive up to the traditional mountain villages of Asfendiou, Zia and Pyli, with the medieval castle of Old Pyli.
Evening. Watch the sunset from Zia, one of the island's highlights, and have dinner in a taverna with a view.
Zia is busy at sunset; arrive early for a table with a view.
Day 3: The south's beaches
Morning. Drive to the beaches of the south coast: Paradise Beach with bubbles rising from the seabed, Agios Stefanos with the ruins of an early Christian basilica facing the islet of Kastri, and Kefalos Bay.
Afternoon. Visit Kefalos village on the hill, the cave of Aspri Petra, and swim at Kampos or Agios Theologos, a wild beach on the west coast.
Evening. Watch the sunset over the sea at Agios Theologos, and have fish at the beach taverna.
Bring water shoes for pebbly beaches and to protect against sea urchins.
Day 4: Nisyros volcano
Morning. Take a boat from Kardamena or Kos Town to Nisyros (about 1-1.5 hours), then a bus up to the Stefanos crater, where you can walk on the floor of an active volcano, with steaming fumaroles and the smell of sulphur.
Afternoon. Visit the villages of Nikia, on the rim of the caldera, and Mandraki, with its monastery inside a cave and the Venetian castle.
Evening. Return to Kos and have a final dinner.
Wear closed shoes in the crater: the ground is hot and uneven.
