This is undoubtedly the most beautiful walk tour on Santorini. It is a 9 km hike and it will take you about 4 hours to complete it, but the view will reward you! Make as many stops as you like to capture the unique scenery and the picturesque Caldera. Wear proper shoes and have water with you. Once you arrive in Oia there are plenty of choices to relax and regain your strengths.
