9Kos – Kalymnos – Nisyros

This route is perfect for travelers who want variety and a touch of adventure. Begin in Kos, a vibrant island filled with beaches, nightlife, and ancient landmarks. Next, head to Kalymnos, famous for its dramatic cliffs and strong local traditions. 

The island has a more authentic feel and is known worldwide for rock climbing. The final stop, Nisyros, is the highlight — a volcanic island where you can walk inside a massive crater and experience a truly unique landscape. This route combines nature, activity, and culture in a compact area.
