Astypalea: Definitely not ideal for a day trip, since the island is far from Kos and therefore less frequently interconnected through high-speed boats (catamarans) or larger ferry boats, but could be an option for a multi-day trip. The butterfly-shaped Greek island is peaceful and looks like an island of Cyclades, due to its narrow alleys, whitewashed houses, and overall intense Cycladic architecture.
Tilos: The island keeps an authentic charm and has managed to fly under the tourism radar, so it is nowadays considered an alternative and serene holiday destination. Bearing almost no tourism development, the island is perfect for those looking for a rejuvenating holiday away from it all.
Halki: The island’s laid-back atmosphere is surely ideal for a tranquil getaway. Scenic-coloured Nimporio houses the island's harbour as well as the island’s only town. In Halki, visitors wish to swim into paradisiac waters and savour the traditional food with a long-desired glass of ouzo. The island is close to Rhodes, connected to Kos through high-speed boats (catamarans) as well as larger ferry boats.
