Hello everyone, I am coming to Sfakia his summer (all August) and I intend on doing this walk from Agios Ioannis down to Sellouda, Agios Pavlos, and finally Agia Roumeli. Are there any organized groups or services to do this hike? Physically I have no issue, I am just concerned about orientation and direction. I like to hike with at least one person just in case. Please let me know, thank you.
