June 25, 2024, View of Snowdon (Yr Wyddfa) Across Llyn Nantlle Uchaf

Nantle Valley is well known for its mountains and ridge. A lot of historic settlements and slate mining. Stunning views of Snowdonia. Road surface is good watch out for sheep moving freely and a couple of cattle grids in this area

Y Garn is the first summit on the traditional northeast to southwest traverse of the classic Nantlle Ridge. The summit is most notable for the excellent vantage it provides towards the striking north ridge of Mynydd Drws-y-Coed – an enticing line. From here, it's a grade one scramble to its neighbouring summit.

One of the most aesthetic sections of the Nantlle Ridge, here the terrain narrows to a grassy crest on the approach to Mynydd Tal-y-Mignedd. While relatively narrow, there's no scrambling involved and it's nothing more than a walk, even under winter conditions.

Y Garn at 633 m is the first summit reached when running the Nantile Ridge from Rhyd-Ddu. It's a striking mountain when viewed from the valley with a great ridge across to Mynydd Drws-y-coed.

Lovely views from the top, climb up isn't bad - can be slippery if its wet and in winter.

On the usual northeast to southwest traverse, Garnedd-goch is the final summit of the Nantlle Ridge. Unlike the peaks towards the start of the traverse, Garnedd-goch's rocky summit is found at the end of a much broader section of the ridge. On a clear day, it's a lovely viewpoint for the Lleyn Peninsula and Cardigan Bay beyond.

Mynydd Tal-y-Mignedd's beguiling east ridge is one of the most entertaining section of the Nantlle Ridge traverse. A grassy arete that connects Trum y Ddysgl to Mynydd Tal-y-Mignedd, it narrows to a slim, green sliver before broadening out again and ascending. While airy, the traverse is a walk rather than a scramble but a head for heights is still required.

This is a relatively flat 4.1-mile (6.7 km) walk that provides lovely perspectives of the lake and the surrounding Nantlle Valley without significant climbing.

Can I bring my dog on the trails around Llanllyfni?

Many trails in the Llanllyfni area are suitable for dogs, but be aware of local conditions. The region has active farmland, so you will likely encounter livestock. Always keep your dog on a lead in these areas. For a shorter outing, the Hiking loop from Nantlle is a pleasant walk where you can manage your dog closely.

What are the walks like that explore the old slate quarries?

The landscape around Llanllyfni is defined by its slate quarrying history. Hikes in the Nantlle Valley often pass by remnants of this industry, including the vast, flooded Dorothea Quarry. These trails offer a unique mix of natural scenery and industrial heritage, with paths winding through former quarry sites and past historic structures.

What should I know before attempting the Nantlle Ridge?

The Nantlle Ridge is a classic Snowdonia mountain walk for experienced hikers. It involves several exposed sections and some scrambling, so a good head for heights is essential. The weather can change rapidly. Ensure you have appropriate gear, including waterproofs, sturdy footwear, and navigation tools. The full traverse is a long and demanding day out.

Are there any good circular walks starting from the area?

Yes, there are many excellent circular routes. For a moderately challenging day with rewarding views, consider the Garnedd-goch loop. This 7.2-mile (11.6 km) trail takes you into Snowdonia National Park, involving a significant amount of ascent to the summit.

Where can I find the best views of Llyn Nantlle?

Several trails offer fantastic views of the picturesque Llyn Nantlle.

What do other hikers think of the trails in this region?

The trails around Llanllyfni are highly regarded by the komoot community, with an average rating of 4.6 stars. Hikers often praise the dramatic ridge lines, the unique scenery of the historic slate quarries, and the fact that it's often quieter than the more crowded peaks of Snowdonia.

Where can I park to start a hike?

Parking is typically found in small, dedicated car parks or lay-bys near the main trailheads, such as those for the Nantlle Ridge or lake loops. For example, hikes often start from near the old Simdde-dylluan Copper Mine. Parking can be limited, especially on weekends, so arriving early is recommended. Always park considerately and do not block access roads.

How difficult is hiking the Nantlle Ridge compared to Snowdon?

While Snowdon is higher, the Nantlle Ridge is often considered a more challenging mountaineering experience. The ridge involves sustained exposure and sections of Grade 1 scrambling, which requires using your hands. Most paths up Snowdon, like the Llanberis Path, are straightforward walks on a clear path, whereas the Nantlle Ridge demands greater confidence and hillwalking skill.

Are there any good waterfall walks nearby?

While the immediate Llanllyfni area is known more for its quarries and ridges, a short drive will take you to some of North Wales' most spectacular waterfalls. Rhaeadr Fawr (Aber Falls) is a very popular destination, featuring a beautiful walk through a valley to a dramatic waterfall. Be sure to park in the designated car parks for this walk.
