Good experience, quality and information - Perperikon is trully an impressive site. For the self-guided tour, we have been provided with audio and text (PDF) guides that had interesting and complementary information. We liked the most the references with the local miths and legends, as these are not always easy to find by browsing the internet. For the audio guide, the voice was pleasant with good and clear English, with a duration of approx 9 min. The organizer was available to support and answer any of our question or request quickly. We received the guides in the morning of the day the tour was booked via Dropbox.
