I couldn't imagine touring the islands of Greece without spending a little time in Santorini. Coming from Naxos the number of tourists was definitely overwhelming, but the scenery made my jaw drop. A a massive volcanic eruption 3600 years ago created the dramatic, 1000ft high cliffs where the main cities are perched. The resulting landscape is distinctively dramatic and beautiful.
My first day on the island was spent getting my bearings in the city of Oia, the oldest settlement on the island. The streets were packed with people shopping, snapping photos and claiming great spots to watch the sunset.
The hike from Oia to Fira was a great way to explore the landscape and experience a variety of views of the caldera (the collapsed center of the volcanic eruption currently filled with water). The sun was merciless, so a hat was crucial for the hike.
