Locals on Serifos have maintained the Cycladic tradition of building white and blue houses so this island is especially photogenic. Visitors to Serifos enjoy many outdoor activities such as biking, hiking, climbing, and diving. This island is also the closest to Athens, lying only a short 4-hour ferry ride away, making it perfect for combining with a trip to the mainland. Be sure to visit the town of Chora while you are there. Yes, just like the capital town in Naxos, this town is also called Chora! This beautiful village is built on two levels with the upper mountaintop area accessible by a staircase from the lower neighborhood. It also has an imposing 15th-century Venetian castle well worth the ten-minute walk to visit.
