It is an exceptional place to go if you know the SECRET trail which goes behind the monastery. It starts from the left of the road, in front of the monastery, with a small arrow indicating Ancient Thera. Follow this little trail for 100-200 meters to enjoy dominating 360 degrees views on all Santorini. We enjoyed guessing where were the different villages we saw as well as watching the planes taking off and landing on the airport. As a bonus, the temperature is 3-4 degrees lower and there is at most a few people, unlike the crowded touristic areas. Be careful winds can be quite strong up there, keep a hand on your hat!
