| Parked in car park to south, along BW then up. Not the easiest to get to, due to walls. My last English and Welsh Marilyn. Great views. | PeterD | 24/04/2024 |

| From Kings Youth hostel. Glorious weather giving fabulous views of Cadair Idris. | Peterb | 15/04/2023 |
| Walked up from our B&B in Dolgellau at 7am on Easter Sunday. Simple to access from the east via the footpath, although would involve bashing through bracken later on in the year | Richard | 09/04/2023 |
| From south side car park | jef | 29/03/2023 |
| 4 mile run loop with Erin from the Pony Path car park to Hafod Dywyll then east .. we started heading up at SH695164 following sheep trods up passed the boulder art which looks like a bored farmers lockdown project … we found an obvious human trod higher up which took us to summit … followed it back down along edge of trees to gate on main track at SH700165 then back through trees and side of lake .. | milejunkie | 15/02/2023 |
| Walked up from Dolgellau on a sunny but very windy day. Approached via Gellilwyd. Cattle roam the first section but ignored us for the most part. The double feature 'lane' was filled with water, so we headed south up the gap between the summit and eastern outcrops, which gives a nice easy route to the top. Fantastic views all round, if a little difficult to stand up in the wind. We descended SW then followed the wall down, which proved to be extremely steep and slippery. From here we visited the fine Bronze Age cairns on the saddle, before returning to Dol as it was getting dark. | thesweetcheat | 09/11/2022 |
| On last morning on a Denise organised trip to kings YHA. Nice walk through woods and pasture. | cjo | 17/10/2022 |
| Quick morning bag run from Kings YH. Sunny, clear, cold when topless! | davechaffey | 16/10/2022 |
| From the Kings Hostel and then the 2 Tumps to the north | Alan Caine | 15/10/2022 |
| Last of 4 hills from Kings. Thunder/Lightning & H/Stones on very top. Then heavy rain. Quickly down into valley and back to YH. | Dusty | 15/10/2022 |
| Anticlockwise route from Kings YH - Craig y Castell 1, Craig y Castell 2 (complete with thunder & lightening on summit) and Dol Gledr. Hail storm on descent. Boggy, tussocky route. | richard69 | 15/10/2022 |

| Gmac parked at old cemetery. Good walk up bike track and seemed to find a path up through bracken. Beautiful evening, picturesque spot. Negotiating a route down through bracken proved much more challenging. Happy days x | elizyanne | 15/07/2022 |

| From car park to SW. Lovely sunny evening. Glorious views of North face of Cader Idris in evening sunshine. On way down got disoriented and surprisingly off route too far NW Once realised had to track south and SE again. | vegibagger | 13/06/2022 |

| Route up from Cemetry car park as per John Glew, but descended off East around forest to rejoin byway, the footpath through wood past Lake to caravan sight then PROW back to hostel. 5.25 miles under 2.5hrs walking time. Really pleasant circuit. | JulieB | 03/01/2022 |

| Nice walk from the single parking place available by the access gate at Gallilwyd Fawr. Climbed with judy55cat Lovely easy walk around the back of the hill via 6972 1614 so approach from south to grassy top. Good views to Cadair Idris which is to save for another day when my achilles heals up! Operated ham radio for SOTA on summit using short wave and Morse Code. | G4OBK (Phil) | 15/06/2021 |

| Much easier than expected. Parked at Ty Nant. Went East through forest on track to avoid the sun, then on through field. At the stone wall, followed faint but definite path along the wall all the way to top. Fantastic views, esp of Cadair. | huwthomas | 31/07/2020 |

| From Gelliwydd Farm, small space near telegraph post, up track then at ruin building turned right along wall to pick up track (starts unpromising as steep grassy field) but track easily picked up above. At gate in wall headed up faint path, improves higher up near forest wall to summit. 2/4 Marilyn | N.Morters | 18/01/2020 |

| Parked car park for Cadair Idris, past farm up south slope. Lots of hideous bracken, must be an easier way. | iangalbraith | 20/07/2019 |

| Parked at the cemetery (SH 6818 1578). Woodland track to YHA Kings, then RoW up through Hafod-dywyll farm. Lot of dying bracken on the slopes after leaving the RoW. | jonglew | 07/10/2018 |
| P near cemetery to SW of Kings YH. Followed a nice woodland path down to near YH then obvious tracks to E. Left track and aimed for a mini Stonehenge feature located at SH 69728 16396 (is it ancient?). Then the inevitable heather/bracken thrash - following feint animal tracks helps. Nice little hill. | ger | 27/09/2018 |

| 3/4 Marilyn day. Craig y Castell from the Cadair Idris car park. Good views of the Mawddach estuary and north face of Cadair Idris. A round trip of 3.3km in 1 hour. (S) | silveracorn_alan | 23/09/2018 |
| From King's YHA, along the old road: we headed for the gully filled with head high bracken, a maze in which we found, by trial and error, tunnels made by sheep. The grassy trods nearer the forest wall that we used for descent were much better and we should have used them to ascend, too. Good viewpoint on an OK day for weather turning showery. Back on the old road, we turned off R for Llyn Gwernan, over field paths to the pay car park, then returned via Nant-y-gwyrddail to Cregennan lakes (free) car park. We'd started our walk from there over Pared y Cefn-hir(qv for log), by far the better of the two summits. A very good day out with Pete, in impressive and beautiful surroundings. | pwheeler | 10/09/2018 |
