A mere mention of the Rhinogs is often accompanied by warnings to anyone who is thinking of tackling them. They are reputed to be some of the roughest, wildest and remote mountains in Wales. What they lack in overall height, they make up for with an abundance of rocks, heather and bogs, often all three at once. This is one of Snowdonia's quietest yet most exciting areas and I was lucky to have some superb weather accompanying me - a day in the cloud on these mountains would be a different prospect altogether.

I started this walk from the lonely farm at Maes-y-garnedd which stands at the end of a long lane entering Cwm Nantcol. A modest sum of £2 is all that's required to leave the car there for the day. In the warm morning sun, the Rhinogs didn't appear all too daunting but I had read up extensively about them so knew what to expect. My route would take me up Rhinog Fawr and Rhinog Fach before crossing the remaining hills to the south; Y Llethr, Crib-y-rhiw and Diffwys.

So, a long day on the cards, not to be made any easier thanks to a large bruise above my knee picked up while walking into a rock on Snowdon - as you do.

From the farm, the route begins easy enough, following a track and then skirting around the back of the cottage at Nantcol. Almost immediately though, things get a little trickier.

From the cottage, there is no path across the marshy ground so, following advice in a book I was carrying, it's best to head in a northeasterly direction, following the general direction of a Right of Way marked on the OS maps. The west ridge of Rhinog Fawr is key to the ascent as it offers by far the easiest route to the summit.

After crossing a ladder stile, the reeds give way to the heather, mostly shin deep and eager to hide hidden rocks and holes. There are still no paths to speak of, at least in the direction I chose to go. Rocks that poke out above the heather are definitely your friend and make some areas a little easier going.
Clambering up the rocks is often easier than ploughing through the heather

I feel inclined to point out the secret to the success of this walk is reaching this point:
The mysteriously appearing path actually sits on the other side of a ladder stile and there is a path to follow for much of the walk once you reach this point. After fighting through the first round of heather, it was a relief to find a trail blazed all the way to the summit.

The summit of Rhinog Fawr
Despite being the first name on most peoples lips when considering the Rhinogs, Rhinog Fawr is actually the third-highest of the range, being overlooked by Y Llethr and Diffwys. However, it is much more magnificent and rugged than both of those mountains and worthy of being the poster boy (or girl!) of the range.

Clip and Moel Ysgyfarnogod
It has a superb view over much of mid-Snowdonia, across the wild Rhinogydd to the north and over Shell Island and the Irish Sea to the west. Rhinog Fawr stands a short distance south and takes up most of the view in that direction, but was shielded by the bright sunshine.

Rhinog Fach and Y Llethr
There's no hiding from the fact that the next leg is a mental as well as a physical challenge, a steep 400m descent followed by exactly the same gain back up to Rhinog Fawr. Much has been written about descending Rhinog Fawr so I knew what to expect and, in all honesty, other than it being steep and quite slow, it's not too difficult.
Heading off the summit
From the trig pillar on Rhinog Fawr, the path heads east and then south to reach an obvious gully. While it appears intimidating at first, venturing in reveals a rocky stone chute that will lead down into Bwlch Drws Ardudwy. There is evidence of a vague path for much of the way down though I imagine that you could do the descent 10 times and take 10 different routes. They will all eventually reach the pass. In all, it took around 45 minutes to make it down the mountainside with my ankles and confidence intact though the troublesome knee was now starting to make itself known.

Looking back up to Rhinog Fawr
The pass of Bwlch Drws Ardudwy is very wet and I failed in my attempt to keep the water out of my boots. If you are to continue to Rhinog Fach, there are two main choices of ascent. The first is a direct route up from the highest point of the pass which is steep and pretty unrelenting. I, however, had been recommended a slightly easier approach via Llyn Hosan which is longer, more gentle and, perhaps, slightly more scenic.

From the pass, a ladder stile crosses a wall and a path makes its way up to the small Llyn Hosan, nestled beneath the cliffs of Rhinog Fach. After passing the tarn, the path climbs once more to reach the valley below Llyn Hywel.

Before reaching Llyn Hywel, I turned back on myself to climb up to the main summit ridge via a broad grassy gully. While this is steep an eroded path leads all the way up. A short walk along the ridge leads to the summit.

Approaching the summit
Rhinog Fawr's summit
After leaving the summit, I made the mistake of heading straight towards Y Llethr where a line of crag bars the way as they fall into Llyn Hywell. Instead, the drystone wall to the east of the summit offers a route of descent. My knee was really starting to hurt now, particularly descending and, in hindsight, I should probably have called it a day here and made my way back to Maes-y-garnedd. However, I tend to be a determined soul and I opted to carry on, despite the distance remaining.
This path off the summit is a bit misleading
Ahead is the looming presence of Y Llethr where a very steep path (a bit of a theme for the day) leads up onto the summit plateau. Though steep, the view back to Rhinog Fach is one of the iconic scenes of Rhinogs and one that shouldn't be missed.

The skies were starting to fill with clouds and they had descended onto Y Llethr's summit by the time I reached it. The mountain presents a distinct change in character for the Rhinogs as the rocks and heather are replaced by grass. From here the walking and navigation are much more straightforward.

Y Llethr's summit
A wall runs along much of the ridge, leading roughly south over the top of Crib-y-rhiw where steep crags plunge to the wide valley below. The undulating path meanders through pleasant rocky outcrops before climbing more seriously to the summit of Diffwys.

Diffwys is one of the geologists - seen from Crib-y-rhiw, the strange, curved shape of the northern slope are the exposed Caerdeon Syncline - a huge geological fold. For the walker, Diffwys has a superb vantage point that brings the Mawddach Estuary into view, as well as Cader Idris and the oft-ignored Y Garn.

There's a fair old trek to get back to Maes-y-garnedd from Diffwys, crossing the uninteresting West Top on the way. From here, a pathless descent of steep grass is required which, given the increasing difficulties caused by my knee, was a tedious and painful affair. I spent some of the descent deliberately sliding down on my backside as it was easier and less painful than walking down.

The outlet of Llyn Bodlyn
Eventually, I reached the bottom of the slope and the river which emanates from the outlet of Llyn Bodlyn, nestled beneath the dark crags of Diffwys. Crossing the outlet of the reservoir is easy thanks to a footbridge which forms part of the reservoirs access road. The road came as a welcome respite to the roughness of the days walking but doesn't last long as Y Llethr's west ridge bars the route to Cwm Nantcol.

A short climb crosses the ridge in the depression that separates Y Llethr from Moelfre and then a long, shallow descent leads down to the farm buildings at Cil-cychwyn. From here it's a mile along the road back to Maes-y-garnedd.

So, what's my opinion of the Rhinogs? In honesty, not too bad - certainty by the route I took. The main difficulty was reaching the stile on Rhinog Fawr's west ridge. From here, there are paths of sorts to follow and the main challenge is the rollercoaster of ascent and descent. I think the reputation of the Rhinogs precedes them and those who decide to take them on will be pleasantly surprised.


  1. Just found this. First trip after lockdown. Clear advie and great photos. Cheers mate!

  2. Im thinking of doing this route but do half and camp, was there plenty of places for wild camping?
