Samothraki
Best for: getting back to nature
Anchored in the northeastern Aegean, rugged Samothraki is a laid-back enclave of sleepy villages with panoramic views. Pack hiking boots as well as a bikini: the island is crisscrossed with numerous trails that wind along rocky gorges, passing waterfalls and natural pools. Mount Fengari (meaning "moon") is one of the highest peaks in the Aegean and, according to mythology, the spot from which Poseidon watched the Trojan War. Various routes of different difficulties trace the peak's foothills, many passing vathres (lakes) that are perfect for mid-hike dips. Don't miss the natural hot springs at Therma, either.
