Parked at layby near small disused quarry, a few hundred metres past the quay at Derryinver. Walk up short vehicle road/track past quarry. This place is now used as storage space by local fishermen for their equipment, but access for hill walking is not a problem. Just after quarry there's a gate. Go through, close gate, and bear left away from fences to get straight onto open hillside. There are some ruins to the left here at the start of the walk. Path of sorts can be made out on the hillside, but not really good enough to follow in poor visibility. Slope is steady but relatively gentle all the way up.
Some details got garbled in the upload. Actual time taken 56 minutes car to car. Distance 4.34km. Ascent to summit at 356m is about 340m. Descent is the same.
