Today we took in the last of Santorini for this trip…. tomorrow we leave for Athens, the next day back to the USA. We walked out to the farthest point in Oia in the morning then hiked the caldera trail up to a little church in the afternoon. The island is quite narrow… we could see out to the sea on both sides. The “outside” of the island is VERY flat, quite a contrast to the caldera side.
