The first ascent of the route "Kallou - Tzovara" (VI, 300m) was realized on 14/9/1997 by D. Kallos - K. Tzovaras.
It is a demanding and quite isolated line, located to the left of the route "Arhontopoulo" and precisely, at the left chimney. The crux of the route is the traverse at the slab of the first pitch. In the next pitches predominate basically chimneys and overhangs, offering on the whole a pleasant route.
It takes about 5h to climb this route.
