3rd and final tump of a circular from Breakwater country park with Lesley. I veered off to climb Tre-Wilmot then we did South stack, using coastal path before i veered off on a fairly good path to the top. Really wild looking rocky terrain. Descent North to reach footpath and Lesley. We took a more direct route back to the start. Next: Rhoscolyn and Hirfron...Dazingdale16/07/2019

A nice walk from South Stack RSPB cafe, enlivened by amusing scrambling over the giant boulders below the crags and interesting slabby scrambling on the left of the summit gully. A gentle stroll down to the path, followed by soup, tea and cake in the cafe. What could be nicer? Probably been up before, but thought I had better check.Gill25/11/2017

A lovely walk from the South Stack visitor centre on good paths all the way. You can park right at the end of the road. Great views! With CH, MH and AM.Mark Jackson25/08/2016
Parked at SH 2260 8326 in the pay and display car park - but was cheap as I recall. Followed quarry track from pond to SH 2219 8350 then struck up on path to the summit. Chose an unsatisfactory route down through bracken on a very rough uneven path so the above route is what I would recommend.G4OBK (Phil)15/08/2016
