The remains of the quarry are huge, both spoil heaps and derelict building. There are also some huge cavern openings that are to be avoided if going on to climb the Moelwyns from here. The workings were underground rather than open cast like some of the Blaenau Festiniog or Dinorwic quarries.

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.

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

Nice steady climb from the Beddgelert side, kicks up in a couple of sections but nothing too stressful. Well worth a visit

This is a proper pass and a good challenge as well. Not ridiculously long but will test you if loaded up. The south face is easily rideable up or down on any bike short of a track bike but the north side is the interesting bit. Mucky and loose after rain and looser and muckier as it goes down. Several gates make way to a ford crossing. Then another, and then another for good measure. The first is the most technical and rockiest, and the last is the longest. Please close the gates!

The Bro Machno region offers a mix of dedicated mountain biking trails and significant mountain ascents that provide a 'pass-like' experience. You'll find challenging landscapes, impressive peaks, and routes with stunning panoramic views within Eryri National Park (Snowdonia).

You can see remnants like derelict slate houses and abandoned tunnels on its flanks. Similarly, routes up Moel Siabod often pass through old quarry workings, adding historical context to the natural beauty.
The Penmachno Mountain Bike Trails, including Dolen Machno and Dolen Eryri, are renowned for their challenging terrain. Dolen Machno is a 19km loop with fast descents, significant climbs, technical single-track, and tight switchbacks. Both loops can be combined for a 30km adventure. You can find more details on these and other routes in the MTB Trails around Bro Machno guide.
Moel Siabod is particularly known for its exceptional 360-degree views in Snowdonia; on a clear day, you can see 13 of the 14 highest peaks in Wales. Cnicht Summit also provides wonderful views and is often less crowded than other peaks.
Yes, the Daear Ddu Ridge on Moel Siabod is a Grade 1 scramble, considered suitable for beginners. It offers a hands-on scrambling experience with low exposure, making it a great introduction to more adventurous ascents.
Moelwyn Bach is smaller and rockier than its sibling Moelwyn Mawr, offering superb views, particularly west towards the Lleyn Peninsula. It's appreciated for its remote feel, providing a true wild mountain experience away from the crowds often found in other parts of the National Park.
The area offers a variety of hiking trails, from moderate loops like the 'View of Cwm Penmachno Quarries' to more difficult routes such as 'Fairy Glen – Betws-y-Coed Village loop'. Many trails provide scenic views and opportunities to explore the natural landscape. For more options, check the Hiking around Bro Machno guide.
The best time to visit is generally during the warmer, drier months from late spring to early autumn (May to October) for hiking and mountain biking. During these periods, the weather is more stable, and the trails are less muddy, offering clearer views. However, the trails can be remote and exposed, so preparation for varied weather is always advised.
The Pen-y-Pass Ascent from Nant Gwynant is a highly regarded climb, voted one of the ten most iconic in Wales. It offers fantastic views towards the summit over approximately 6 km. Another scenic option is the Llyn Gwynant Climb, which provides amazing views along Llyn Gwynant and Snowdon.
Some trails, particularly the Penmachno Mountain Bike Trails, are remote and exposed in sections, with limited phone signal. It's crucial to be well-prepared with appropriate gear, navigation tools, and emergency supplies. The Foel Frech Off-Road Pass is also noted for its remote feel and challenging conditions, especially after rain.
Yes, there are several running trails in the vicinity. Options range from moderate routes like the 'View of Moel Siabod – Pont-y-Pant Car Park loop' to more difficult ones such as the 'Flowy Singletrack Descent loop from Capel Garmon'.
