From the Santuario di San Luca near Monte Acuto, followed the signed path to Caccume. This path is not on the paper maps, but is on the peakery map. It is well signed and traverses the side of Monte Gemma without losing or gaining much height. The only challenge to those like me who try to avoid GPS and read the landscape is judging where to break off and head up Colle di Trevi. One is tempted to do so before you round that hill and it might well be possible, but if one continues through the beech and oak forest, the light of the sky gives a certain indication that the right moment is coming. The CAI signs actually continue up Trevi which is comprised of three or so minor rises, before magically disappearing at the foot of the beginning of the ridge of Monte Gemma. From here I climbed the first peak of this ridge, then descended and went along to Punta di Torricelle. Returning to the saddle between Trevi and peak 1011, I rounded the north side of Trevi on a faint path which became clearer toward the sorgente (a concrete basin really). From here the path became a little tighter but clear enough, descending to the ridge to the east. Soon after things went a little wrong. I'd anticipated a marked path descending to the road to Supino in the valley to the north. There was a path, faint in the leaf covered wood, and marked (as seems to be the way sometimes) only with thin plastic strips hanging in the trees. At a certain point I lost this path, for what is was, and was unsure where to make the descent. Mud, chestnut leaves and boots no longer with any grip make for a slippery combination, and I landed on my backside several times, once sliding a good couple of metres. Had to climb back some and eventually found a path, deeply cut in the mud (never seen such a thick layer of it in these typically rocky hills) which led me to a gravel then asphalt road and civilization in the form of Supino. On reflection I think I'd tried to descend too soon, and one probably had to cross the rocky shoulder of the first peak on the ridge before descending more drastically.
