The Dirfys is basically a mountain range in on the Evia island close to Athens. The highest peak on that range is the Delfi with an altitude of 1743 meter. I hiked up this mountain in fall 2018 since I spent some time in that area.
Greece in fall offers some amazing spots where you can see the summer fading away in its most beautiful way. The Agali Gorge Hike is definitively one of those spots just a 2 hours ride away from Athens by car.
Early September 2017, I went to Greece and also found some time to hike up the highest mountain of Crete – the Psiloritis (2456m). Below you can find some short information around this easy hike.
