Crag is situated in an ancient quarry. The cliffs are really vertical, and sometimes get even steeper. Hence, routes are technical and sometimes very demanding as for resistance. In summer it can be very hot (especially on the South Wall. Late autumn, Winter, and earluy Spring, East Walls can be cold and wat, South Wall may still offer good climbing. A 60 m rope is sufficient.
It's a quiet yet impressive spot. You will often see hikers pass at the top of the cliff.
Crag is situated in Natura2000 area, so no litter, no fire, no camping!
Acces by car:
Arriving in Olloy-sur-Viroin, coming from the East, don't take the Rue des Mines towards the center of Olloy (a street crossing the Viroin) but instead turn right, follow the 'Rue Autre Côté de l'Eau' for about 500m until the 'Rue de la Goulette' at the right (3 parling places here at the roadside). You could drive 30 m further into the 'Rue Autre Côté de l'Eau', then turn right and drive steep uphill (3 parking places here), but it's rough ground.
Acces on footh
So better walk these last meters, and continue into the trees, following a steep path that, 100m further, splits in two? Take left here and continue following the sinuous path untill arriving at the entrance of the quarry, some 300m further.
