This part of the E4 European trail ascends on the east slopes of Agia Irini Gorge with amazing views to the surrounding pine and cypress groves and concludes in the plateau Omalos, the starting point of many popular trails in the White Mountains (such as Samaria Gorge, Gigilos Peak and Kallergis shelter).
Starting from Sougia, apart from the gorge of Agia Irini, we can choose the alternative route that comes through the beautiful settlement Koustogerako. We initially follow the asphalt road that passes through the gorge and then follow the road that reaches the village Livadas and Koustogerako. From there we can reach Koustogerako at an altitude of 500 meters. The route from Sougia to Koustogerako main square is entirely in paved road. However, there are some subpaths you can follow, such as the nice stone paved trail of Livadas - Koustogerako.
From Koustogerako main square we follow the dirt road to the southeast that ascends to the church of Transfiguration of the Christ (Metamorfosi). We meet the church and keep walking in the main dirt road for about 2km (from the village square). At the end of the road we meet a pen and keep walking in the path heading north. The trail from hereon is signed with red marks, heads northwards and approaches the bare peak in front of us. After several kilometers we meet the road to Greleska observatory (on the left) and turn right till we meet the road connecting Agia Irini to Omalos and turn right. We soon pass the position Seliniotikos Giros, namely the southwest passage to the plateau Omalos, where we stop.
As the entire route needs 7-8 hours to explore, we suggest that you drive the first part to Koustogerako and then walk the rest 4:30 hours to Omalos plateau or break the course into two days (Sougia - Koustogerako and Koustogerako-Omalos)
