If you go to the Kritinia Castle round, you come from the bottom of the beach into the gorge. The beach is littered with big stones and garbage and not easily accessible. You can not find a way anymore. At the end of the beach but then the entry into the gorge. Long pants would have been desirable. The path is partly steep and overgrown and on the right side it goes pretty steep and deep. The whole about an estimated one kilometer. Once you have reached the coastal path that leads down to this beach, there are no shortcuts anymore. Man has to go down to the beach and up the gorge again. So take enough water with you and definitely go out in daylight.
