No special access issues
From Massouri head for Arginonta until you see the marker for Galatiani/Black Forest. About 300m after this you should see the sector marker for Cave from which the well-marked trail starts. There is a bit of a scramble between sections.
Sevasti heads uphill from the start, over loose scree up the gully, keep following the cairns that take you between the left walls and upper cave sector.
Parking down from the white marker for Cave.
