Cobblers. I had a lovely evening there last year. Parked free in a layby above the path start at Ynys Ettws, walked up (starting at 6pm) past the hut, left bank of the stream until an obvious traverse. Soloed Parsons Nose, then immediately traversed left to find a stream which I descended, with many slips and slides and falls over falls into pools, in the dark at the bottom. Then headed east again below the foot of the nose in knee deep bogs, (in the dark) and found my path and descended back to car. A fantastic epic, certainly not wasted, but spoiled only by lack of food at 11pm within thirty miles.
