Yes, that really is the name of this sector. However, this is not in reference to the small cave that has a couple routes, but rather an incredible underground cavern that alone is worth a visit.
Easier routes on the gray faces to either side of the above-ground cave. Harder routes on the orange rock.
See the 2010 version of the Kalymnos Rock Climbing Guidebook (Cave is sector 9).
