We will be in Rethymnon at the beginning of May. We would like to hike along the Mili Gorge, but we do not have our own transportation and would prefer not to join a group. Is there public transportation from Rethymnon to the beginning of the trail? Is the trail clearly marked? Where does the trail end, and is there transportation available back to Rethymnon? Thank you for any advice you can provide on this topic.
