Day 3: Coastal Relaxation & Kefalos Exploration
Head to the eastern coast for Kefalos Beach, known for its golden sands and the ruins of the ancient city of Kefalos. Rent a bike to explore nearby villages or take a boat tour to nearby islets. In the evening, return to Kos Town for a leisurely meal at a rooftop restaurant with views of the Aegean.
Day 4: Agios Stefanos & Cultural Highlights
Spend the morning at Agios Stefanos, a serene beach with clear waters and windsurfing opportunities. Later, visit the Asklepieion's Museum to delve deeper into its medical history. The afternoon is free for shopping in Kos Town or visiting the Archaeological Museum, which houses artifacts from the island's ancient past.
Day 5: Volcanic Adventure to Nisyros
Book a day trip to Nisyros, a volcanic island just 20 km away. Arrive via boat and hike up to the caldera for dramatic views of the active volcano. Explore the village of Pyli, with its colorful houses and thermal springs. Return to Kos in the evening, tired but invigorated by the day's natural wonders.
Day 6: Leisure & Local Culture
Take it easy today. Visit a local winery or olive oil producer for a tasting session. Alternatively, take a boat trip to the nearby island of Kalymnos for snorkeling. In the evening, enjoy a traditional Greek night out with live music and dancing at a taverna in Kos Town.
Day 7: Departure & Last-Minute Exploration
Use your final day to revisit any missed spots or simply relax by the sea. If time permits, take a short hike to the Mavroneri Waterfall, a hidden gem near the island's northern coast. Pack up and depart with memories of ancient ruins, volcanic landscapes, and sunsets over the Aegean.
