Kollita Gorges, i.e. Twin Ravines are located nearby the picturesque village Argyroupolis, about 22km southwest of Rethymnon city. They are named so, as they consist of two parallel canyons that end near Kato Poros settlement and is part of the E4 trail. The first canyon on the east is called Moudriano Gorge, while the west gorge is Kato Poros Gorge of Vilandredo Gorge, mostly known as the main Kollita Gorge.

The route starts from Kissamos and is the first part of the European E4 trail in Crete. After crossing the villages Kato Palekastro, Korfiano and Grigoriana, we arrive at the ancient city of Polirinia and from there we cross the lush green villages Galouva, Lusakies Zahariana and, finally, Sfinari with the beautiful beach.

This part of the European trail E4 starts from Sfinari and ends at Chrisoskalitissa. It is one of the most beautiful and wooded parts of Crete with astonishing sea views. First we go through the desolated village Ano Sfinari, then Kambos, Plagia and Keramoti.

From the exotic lagoon of Lafonisi, located 4.5km south of Chrysoskalitissa, starts the coastal trail to Paleochora. Originally, it comes from the stunning Kedrodasos beach, passes from the church of St. John, the ancient sanctuary of Viena, Krios Cape, and then from the beaches to the west of Paleochora. The trail is one of the nicest parts of the European trail E4.

This amazing hike is about 16km long and takes about 5-6 hours. The trail is clear and well-marked with the typical E4 back-yellow signs. It crosses the archaeological site of Lissos, where you can find water from the local spring. It isn't too difficult but plenty of water, sun protection, and steady shoes are recommended.

The part of the European path E4 that connects Chora Sfakion with Frangokastelo and then with Rodakino is all on paved road and can be visited even by car.

Starting from Sougia, apart from the gorge of Agia Irini, we can choose the alternative route that comes through the beautiful settlement Koustogerako. Then the trail continues and crosses the pine wood by Olisma and conludes at Seliniotikos Gyros, i.e. the southwest passage to Omalos Plateau.

Some of those who cross the gorge of Agia Irini, start their course from the plateau Omalos and reach the village of Agia Irini, before entering the canyon via the E4 trail. The trail has amazing views to the groves with the full of the typical cypress trees of the White mountains.
