The path to the green gorge of Agios Nikolaos with the amazing waterfalls starts from the Zaros Lake and ends to one of the forest of Greece, the Rouvas forest.
It is also a part of the E4 European long distance path, Zaros- Rouvas Forest- Nida.
The gorge, from Zaros Lake to Rouvas forest and back, is about 10 kilometers and it takes about 4 hours.
Agios Nikolaos monastery (from where the name of the gorge came) is 900 meters from the lake.
The cavernous skete of Agios Efthimios is in the eastern edge of the gorge, 500 meters beneath the Agios Nikolaos monastery.
According to the tradition, the nuns of the Agios Nikolaos monastery killed the hermit, Efthimios, when they saw him in the gardens of the monastery wearing an animal fleece.
A monastery state may have flourished in the entrance of the gorge as in many gorges of Crete.
