From South Stack. Yellow lines force you to use the P&D CPs. The P&D machines are liable to switch on whilst you are away from your vehicle. Nearest problem free, free, parking is at SH217813 | Isbjorn | 30/01/2024 |
Up from car park to east with Twiggy. In cloud. Had trouble finding way down. In hindsight, our intended direction wasn't too clever. | desperate dan | 07/10/2023 |
After bagging Yr Arwydd, I parked at SH 2213 8213. Easy route finding straight up, but problematic finding a route down the lower section through the hawthorn bushes and bramble. 
 
Avoid the Quarry area, head for the Reservoir on the descent. | chillyman8 | 20/09/2023 |
A quick diversion off the coastal path to the trig point at the top. | PhilipChaston | 08/09/2023 |
Climbed Holyhead Mountain for the second time, this time with my Nephew. Made our way up from the Breakwater Country Park carpark. Spent half an hour or so at the summit watching the ferries dock in the harbour below. | cactus_chris | 16/08/2023 |

Parked at small car park on right from entry road to south stack, before you turn right across the bridge. Through barrier to right and up through small path through heather and gorse. Steepish and craggy but not not too challenging. Great views and a bench at the top. Back down same way but visited the quarry on the way back down. | Tribal2er | 24/07/2023 |
Nice steady work, you have to pay a small fee to park. | Brian Chambers | 22/07/2023 |
Parked in the RSPB The Range car park. Pleasant circuit around Coastal Path and up to summit, then off North East path and then down to North Stack then paths back to cafe for an ice cream and along road to car. 8.6 mile leisurely circuit. | JulieB | 07/06/2023 |
Ran from Holyhead to South Stack - lighthouse not open - then along the coastal path and up to the trig at the summit for a repeat visit, 15 years later. | madaddo | 07/05/2023 |
On the coastal path from Trearddur Bay | Lancylass | 04/05/2023 |

Detour from running the coast path with Pauline … what a lovely baby mountain .. rocky and heather in flower reminded us of the Rhinogs | milejunkie | 05/09/2022 |
Cycled across Yns Mon from Bangor checked into a rather grotty hotel (avoid the Boatshed!) then cycled up to the base of the walk at Pentre Palla. Good path up in the late afternoon sunshine but somehow managed to find myself stuck in a field of bracken and ended up with scratched shins! Hardly a soul about. | pclyndes | 01/09/2022 |

Parked in the South Stack car park. Followed the tracks across the access land to the impressive summit of Holyhead Mountain, then back along the coast path, going as far down the steps to the lighthouse that was permitted. A round trip of 8km taking 2h 40m. | silveracorn_alan | 18/08/2019 |
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... | Dazingdale | 16/07/2019 |
Easy walk up from South Stack car park. Low cloud (fog horn sounding) so no view possible. | Eliza100 | 11/07/2019 |
