The Arenigs are a less walked group of Snowdonian peaks, yet Arenig Fawr with its central positioning, enjoys huge panoramic views across most of Snowdonia. Here’s a circular route that we walked early on a very frosty January morning. The GPS track reported 7.25 miles of distance with about 2000 ft of climb. Allow 4 hours or so – more in adverse conditions. The ascent follows paths that are generally obvious whilst the descent & return crosses un-pathed grassy slopes before following tracks & lanes back to the start.
We start at a small lay-by on the minor road south of Llyn Celyn (if no parking is available here, then park at the old quarry just west of Arenig village). Cross the lane and follow the track uphill away from the road in an initially south-westerly direction. This path twists and turns over the moorland of Moel y Garth with beautiful views down on your left towards Bala and Llyn Tegid.
The track gives access to the small dam of Llyn Arenig Fawr and we shall soon find ourselves descending slightly to this beautiful lakeside. Here you will find a small walker’s bothy that could provide some useful shelter on a less pleasant day. Cross the ladder style next to the bothy and head across just below the dam.
If your are lucky enough to have great weather (as we did) the morning reflections in Llyn Arenig Fawr are glorious and it is well worth while pausing to soak up some of the tranquillity.
Now we must climb up the hillside to the south of the lake, via Carreg Lefain and on to the point known as Y Castell. The climb is steeper here and follows a smaller path but the way is clear and there are no significant obstacles.
Having crossed an old dilapidated fence-line near Y Castell, we continue ahead, slightly less steeply for the moment. Shortly we will find ourselves walking parallel to another fence-line and with great views of Arenig Fawr ahead. Whilst there are various options here, we chose to cross the fence-line to our right and head uphill on to the shoulder of Arenig Fawr.
Now progress consistently uphill south westerly towards the summit. There’s a little patch of scree and boulders but the path makes for easy crossing along its upper edge. Eventually you will notice the summit trig point ahead of you.
The views from the summit are spectacular, though you will need a clear day to appreciate it at its best. Rhobell Fawr & Cadair Idris to the south (see header feature photo), Snowdon a little over 17 miles to the north plus Rhinogs, coastline and more to the west. As so often, there was a little haze on our morning but still very enjoyable views.
There are lots of possibilities for the descent from here, we chose to partially retrace our steps for a few metres to the NE. A westerly facing gully will be noticed just beneath you (headed by an old post when we were up there). Drop down through this gully and then bear to your right (NE again) to carefully descend on to the rough grassy western slope of Arenig Fawr.
From here we are crossing pathless open access land to descend towards the old abandoned farmhouse of Amnodd-wen. As you get lower down the slope, head for the gateway through the stone wall and then down onto the track just south of Amnodd-wen, turning right (northerly) when you reach it. It’s worth pausing at Amnodd-wen to look back at the mountain you’ve just crossed, as well as to perhaps consider what life was like living here in years gone by.
Now follow this track to the north. When you meet the old railway line do not stray on to it, just continue to follow the track back to the local lane. When you reach the lane, turn right on to it and follow it back through Arenig village to where you parked. A beautiful walk which you may well have all to yourself.
