Revisit with Peterborough MC friends Lies, Melisa and Pawel, on a day when bigger hills rained off, round of the 3 Rivals from car park to SW. Finding the long lost original trig pillar lying half buried in the summit shelter was a nice bonus.RHW17/12/2017

With Trefor. Parked in car park north of Llithfaen. North top (aerial) first then south on path to main summit. On to Tre'r Ceiri after which must be the best example of a hill fort in the country and is well worth a visitmike.hoult07/04/2017
Great views clear day. Whole Llyn peninsula outstretched. very slippery summit in the wet, Worth the climb.Peter_wth04/02/2017

Second ascentPeteF25/09/2016
I'm sure this is a lovely hill, but with no views I couldn't verify that! High winds also made it tricky getting any decent snaps of the summit area. Up from car park to SW to Bwlch yr Eifl. N top first, then onto Tre'r Ceiri.jonglew20/08/2016
Evening ascent in mist from high car park at SH353440.Tony J20/08/2016
Fine summit of boulders and heather topped with a huge ancient cairn. Climbed from Trefor via Bwlch yr Eifl track and returned same route early in morning. Climbed with Labrador. Mixed cloud and Sun with extensive views of the whole Lleyn peninsula, Cardigan Bay, Anglesey and Snowdon. Total time 2.5 hours.jamessteel10005/08/2016
Parked in car park in Llithaen (SH 35636 43126). Took B 4417 east for 100m, then lane north past Tynyparc and track onto moor. Lost path in the hill-fog, but eventually located path by wall north to the summit. Walk continued to Tre'r Ceiri. Solo.marktrengove11/06/2016

Came up here as a detour on coast walk from Nefyn to Trefor. Climbing up from sea-level at Nant Gwrtheryn, this is a strenuous walk, the path from the east is faint and very steep. Two Bronze Age cairns on the summit, one very impressive the other (to the southwest of the big cairn) quite trashed. Wonderful views. We couldn't find a path northeast from the summit so free-styled a route over the boulders and on towards Tre'r Ceiri.thesweetcheat08/05/2016
Parked east of the village called Llithfaen. Several routes up. Well worth a visit. Weird 4 metal bit out of the trig point. Excellent views and huge iron age fort again clearly seen. Must have been a well fought over area once. Wind surprisingly strong rain becoming heavier. Good final peak. Starting to get into these marilyns. Company: Soloiandesbottes01/01/2016
Porth-y-Nant upper car park at SH353440 – East along a decent path & then NE up Llyn Coastal Path – After passing through kissing gate in wall, headed up through the ramparts to the summit of Tre’r Ceiri, probably Britain’s best preserved Iron Age hill fort – Exited through the western ramparts & then up good path through the heather to the summit trig point.

Started at Trefor beach car park and took in a bit of coastal path before heading up to the bwlch then up the lower hill and mast before coming up here to this fine top and trig point.Father Ted10/10/2015

Took a large group up from car park above Nant G, including 2 who'd never been up a hill before! Fears of height and cramp meant walk cut short after summit - will need to come back for Tre'r Ceiri!huwthomas15/07/2015

Start ~ 366433. Climbed up to Caergribin and found a faint path that led directly to the summit. Fantastic views in all directions. Descended to the West and took in the hillfort on Tre'r Ceiri, well worth a visit. With Wombourne.steve hudson03/03/2015
Parked at GR 366433, room for one car. Climbed very steep grass slope to Caergribin then a faint path leads to the summit marked by a trig point. Excellent view point but difficult to take photos because of the extreme wind. Descended via the hill fort on Tre'r Ceiri, well worth a visit. With SH.wombourne03/03/2015
From the car park at Mount Pleasant - east on a good path and then north west to the summit. Great views. Solo.bolton09/08/2014
We'd hoped for a view but all we got was cloud, climbed from the hill fort.bardolph20/04/2014

From B4417 minor road junction to southtim74709/03/2013
Parked to S and tried to follow paths but they kept petering out. Quite a bit of clambering over rocks in the latter part of the ascent and the top was covered in mist so my compass came in handy on the descent.clivevilla15/02/2013
W Jenx, from car park to SE, jncn w coastal path. Tracks at first but higher up rough ground inc. rocks in deep heather. Trig point on top in rocks w. summit adornment. To East found a good descent path all way to just short of car park!nordicstar11/03/2012
Xmas trip - Pete, Rich et alrichardsun02/01/2012
Started just out of village of Llithfaen. With Mark. Fantastic day. Got a little lost on the descent in fog. Very windy but sheltered in the Kisu.Saggers26/11/2011
the trig pillar now has metal box section number "4" attached to the top, which makes the most annoying humming noise in the gentlest of breezes, problem solved with a banana skin or two stuffed into it's open end. (removed of course on departure).George Gradwell24/07/2011
Ascent from car park to immediate southwest. Lleyn Coastal Path was closed for renovation. Had to approach and return up south side path. Incredible view: Eilio, Elidirs, Nantlle, Carneddau, Garn, Glyders, Snowdons, Siabod, Aran, Hebog, Cnicht, Moelwyns.nddavies20/06/2011
