"Like all crags on Penteli, Dionysos is established on the walls of an old marble quarry.
Marble extraction of course has ceased long ago, leaving behind an interesting
climbing venue. Climbing here features vertical faces, cracks, arêtes and occasionally
overhangs and roofs. Marble always involves an interesting kinesiology which can be
considered a kind of its own.
Dionysos is the last part of the mountain where the forest still remains intact where
all the rest has been destroyed by forest fires. The place is usually cool enough to climb
even in high summer. Rock quality is generally good, however one should always
remain vigilant as loose rock parts might still be present, especially in the most recent
routes. The place offers a great variety of routes especially in the lower and middle
range of difficulties.
Although the routes are not especially high they are quite aesthetic in general. Combined
with the fact that the place has a hospitable aura (which also makes it ideal for
children or non-climbers), it is certainly worth a visit. Route setting at the time of
writing is ongoing, therefore new routes are likely to be added (or the existing toprope
routes to be equipped with bolts) in addition to those presented here."
