Rainbows on mountains tend to be a mixed blessing as they are a pretty sure sign that you are about to get wet! However from the photographers point of view they can also signal some great light, with sun mixed in with dark moody clouds. This was the view from near the summit of Cnicht - otherwise sometimes called the Welsh Matterhorn due to its pointy appearance from the village of Croesor. To the right of the picture is Moel Hebog which rises steeply above the pictuesque village of Beddgelert.

Looking south over Moelwyn Bach the view opens out to Trawsfynydd Lake with the misty mountains of (left to right) the Arans, Rhobell Fawr, Cader Idris and Y Garn.

The long abandoned Barracks and Mill buildings of Rhosydd Quarry in the Moelwyn mountains of North Wales on a changeable day last September. A break in the heavy cloud allowed a burst of sunlight through that lit up the shiny slate rubble to make it look a bit like water. The dark buildings stood out against the lower slopes of Foel Ddu.

The view across the deep valley to Moelwyn Mawr is impressive, particularly in moody weather!

The flat topped summit can be difficult in mist, hard to find the very top, and also to navigate off to find the route to Moelwyn Fach - you have to double back, and then descend to the right.

The spartan barracks at Rhosydd, a hard place to live and work, not far from the summit of a mountain.

A fine rocky and in places narrow ridge, and you will often have it all to yourself!

Yes, the area is excellent for circular hikes. Many trails explore the Moelwynion mountain range and return to their starting point. A great example is the Moelwyn Bach from Croesor loop, a moderate route that offers sustained climbs and rewarding views of the surrounding mountains.
The hiking around Llanfrothen is defined by the rugged landscapes of Snowdonia National Park. You'll find a mix of challenging mountain ascents, paths through historic slate quarries, and gentler walks through the valleys. The terrain can be steep and rocky, especially on summit routes.
While the region is known for its challenging peaks, there are easier options suitable for families or those looking for a less strenuous day. The Ascent to Cnicht – Cnicht loop from Croesor is a shorter, accessible trail that leads through the valley towards the mountain, offering fantastic scenery without a major climb.
Dogs are welcome on many trails in Snowdonia, but it's important to be mindful of the terrain and livestock. The area is home to many sheep farms, so dogs should be kept on a lead, especially during lambing season (typically March to May). For more challenging routes with scrambles, ensure your dog is experienced and comfortable with rocky ground.
The main hiking season is from late spring to early autumn (May to September) when the weather is generally milder and daylight hours are longer. However, Welsh weather is famously unpredictable. Always check the mountain forecast before you set out, as conditions on the summits can change rapidly, even in summer. Winter hiking is possible but requires specific skills and equipment due to snow and ice.
Most hikes, particularly those for Cnicht and the Moelwynion, start from the village of Croesor. There is a community-run car park in Croesor which operates on an honesty box system. It can fill up quickly on weekends and holidays, so arriving early is highly recommended.
The summit of Cnicht, often called the 'Welsh Matterhorn', is a primary viewpoint offering panoramic views across Snowdonia. Many routes also pass through the remains of old slate quarries, offering a glimpse into the region's industrial heritage. For a different kind of scenery, the gardens at Plas Brondanw, former home of Sir Clough Williams-Ellis, are nearby and offer splendid views of the mountains.
The trails are very highly regarded by the Komoot community. Hikers frequently praise the dramatic mountain scenery, the sense of solitude on less-trafficked paths, and the rewarding challenge of the summit climbs. The mix of rugged peaks and historic landscapes is a consistent highlight in reviews.
You can find around two dozen curated hiking routes in the immediate Llanfrothen area on Komoot. These range from short, easy valley walks to demanding full-day mountain expeditions, with a roughly even split between moderate and difficult trails.
Absolutely. The region is a great destination for those seeking a challenge. The Moelwyn Mawr summit – Cnicht loop from Croesor provides a strenuous day out, tackling multiple peaks in the Moelwyn range. For a true test, the knife-edged arête of Crib Goch on Snowdon is a classic scramble located a short drive away.
Sturdy, waterproof hiking boots with good grip are essential due to the rocky and often boggy terrain. You should always carry waterproof trousers and a jacket, as well as extra warm layers, regardless of the forecast. A map, compass, and/or a fully charged phone with a GPS app are crucial for navigation, as phone signal can be unreliable in the mountains.
