4Folegandros

Folegandros is just 13km (8mi) long and 5km (3mi) wide, but there’s no chance you’ll be bored. This rocky island an hour’s ferry ride from Santorini is ideal for lazy days spent swimming in blissfully blue coves, gorging on Greek food in tavernas and hiking through orchards and hamlets in the island’s verdant north.

Don’t miss the medieval town of Chora, built on a cliff 200m (655ft) above sea level with a winding path up the mountain to the secluded church of Panagia for unforgettable sunsets.
