The site of the 1600 BC village which has been excavated has just been reopened. We visited Santorini in 2006 and 2009 and unfortunately couldn't visit there. It has opened now but there are no guides on site and very little signage. Fortunately our hotel steered us to a private guide, Nikos Kaldrimidis <email@example.com> who did an excellent job,understands both the historical details and the geology along with being personable and facile in English and German. He gave us the best tour we have ever had! We recommend him highly!
