From Heraklion head towards Moires, go past Agia Varvara, to Agioi Deka. In this village, don't miss the left-hand turn to Vaghionia which you go through to reach Loukia and then Kapetaniana, at which point the road become a track! A 8km track connecting to Ag.Ioanni, maybe tarmarcked or asphalt by now... haven't been there since 2010! The landscape is eye rewarding and vast! Park on the left, 300m after the chapel.
