Today, the highlight was a late afternoon sail through the center of the volcano, called The Caldera. Santorini used to be a single island with a center peak, which was actually a volcano–and in fact, is still an active volcano today. Nearly 4,000 years ago the volcano erupted, an event that is considered to be one of the largest and most devastating eruptions known to man. The eruption caused the center of the volcano to collapse into the sea, creating the extraordinary rocky walled perimeter islands of Santorini as we know it today.

The evening culminated in a beautiful sunset, which is the photo you see above. Somehow, taking time to observe the sunset always feels like prayer.
