In the dry climate of eastern Crete, most gorges remain without flowing water during the summer months. However, there are also green routes with springs and waterfalls, the most characteristic example being the Richtis Gorge. The gorges of Lassithi are mainly formed in the mountain ranges of Dikti and Thripti, in mountainous Mirabello and around Sitia.

On Dikti, notable routes include the Sarakina Gorge near the village of Mythoi, the Kritsa Gorge, the Adrianos Gorge, the Havgas Gorge near Kalamafka and the Havgas Gorge of the Lassithi Plateau. On Thripti, amid rocky and pine-covered slopes, lie the gorges of Pefki, Orino, Ahlia and Milonas, several of which form seasonal waterfalls.

The Zakros Gorge, also known as the Gorge of the Dead, dominates the area around Zakros. Its name comes from the Minoan burials discovered in caves along its walls. Nearby are the gorges of Katsounaki, Lamnoni, Agia Irini and Pervolakia. In mountainous Mirabello are the gorges of Kouroukoulos, Havgas above Plaka and Skotini. Lassithi is also home to the imposing technical Ha Gorge, one of the most demanding canyoning descents in Crete.
