Katholiko Monastery is about 20 kilometers east of Chania, in the Avlaki Gorge - a wild area full of caves, not far from the sea, on Cape Akrotiri. The cave where Saint John the Hermit died in the 11th century became one of Crete's ascetic places, and, in time, a place of pilgrimage. Its popularity grew so much that in the 17th century, Venetian nobleman Jeremiah Tzagarolo was commissioned to build a monastic complex of impressive complexity.
Today you can only see the ruins of the edifice, with the bridge over the gorge's river, hermits' cells, and several other structures.
To reach Katholiko Monastery, follow the cobbled trail that starts at the Gouverneto Monastery and walk about 800 meters. Mind your footwear, as the walk is steep. On your way, you will pass the Church of St. Anthony and the Cave of Panagia Arkoudiotissa (also known as Cave Arkoudospilios or the Bear Cave) - both worth visiting.
