3Sifnos, for pretty churches and exhilarating hikes

Fans of Greek churches will love this Cycladic island. The cutest is the Chapel of the Seven Martyrs, built on a cliff edge in the Kastro village, perched above the Aegean.

Shaped like a little fortress town with winding alleys, Kastro is dotted with more churches, taverns and bars. Follow the Sifnos Trails – 62mi (100km) of marked hiking paths – through villages and olive groves, or take a pottery class to learn how to shape the Sifnian clay.
