At the western end of the long beach of Chatzivolakas on the island of Chrissi, we find the beach Avlaki. Avlaki has rocky seabed, like almost the whole island. At the end of the beach there is the second harbour of the island at position Spilios and the only house in Chrissi built in the middle of the 20th century. The name Spilios (cave) is taken after an old house built in the rock.
Adjacent to the house there is the old saltpan, which in winter turns into a small wetland. Very close to Spilios there is the church of Agios Nikolaos, many wells with fresh water that gave life to the cultivations that were developed here in the past, ancient graves and traces of buildings that were probably facilities for the production of the Tyrian purple. At the harbor we can see traces of an ancient quay that probably was the harbor of the ancient settlement.
