Agia Irini is located between Therma and Kardamena and is a part of Kos only reachable through the sea. The so-called underground monastery of Agia Irini, actually a small chapel dedicated to St. Irini, is located a few kilometers southwest of the thermal springs (Therma). You’ll find a tiny, stony, beach surrounded by steep cliffs and rocky masses; a wild, isolated and imposing landscape at the foot of Mount Dikaios.
