The Route:
We’ll begin our journey at the Dôl Idris Car Park, situated in the foothills of Cadair Idris. From here, we’ll head up through the eastern approach, which offers some of the most spectacular and tranquil views of the surrounding valleys and peaks, including the Cwm Cau valley, with its remarkable glacial landscape.
Cwm Cau and Llyn Cau:
The first major highlight on our route is Cwm Cau, a striking U-shaped glacial valley. The valley is home to Llyn Cau, a stunning lake nestled beneath the towering cliffs of Cadair Idris. Llyn Cau’s crystal-clear waters reflect the surrounding mountains and are a picture-perfect spot to rest and enjoy the beauty of this dramatic location. According to legend, the lake is associated with the mythical figure of Idris, said to be a giant who lived in the area.
As you stand at the lake’s edge, you’ll feel dwarfed by the towering slopes that surround you, making it clear why Cadair Idris holds such an esteemed place in Welsh mythology. This is an ideal location for some quiet reflection or a quick snack before we continue our ascent.
Ascent to Penygadair:
From Llyn Cau, the path steepens as we begin the final push toward the summit. The route is rocky and challenging, but the reward is worth every step. As we ascend, the views expand and become more dramatic. To the south, the green valleys and ridges of Snowdonia stretch out before us, while the northward vista reveals the Cardigan Bay coastline, where the mountains meet the sea. If the weather is clear, you can spot as far as the Llyn Peninsula and Ynys Enlli (Bardsey Island), sitting out on the Irish Sea.
As we approach the summit of Penygadair (893 meters), you’ll be treated to panoramic views of Snowdonia’s mountain ranges, including the Crib y Ddysgl ridge, the Aran mountains, and Yr Wyddfa (Snowdon), the highest peak in Wales. Looking to the west, you’ll see the vast expanse of the Cambrian Mountains and the rugged coast of Cardigan Bay.
At the summit of Penygadair, the landscape unfolds in all its glory. You’ll be able to see the whole of Cadair Idris, with its dramatic cliffs, deep ridges, and glacial valleys. The views of Snowdonia’s wild beauty are unmatched, offering a 360-degree panorama of the surrounding peaks and valleys.
The Terrain:
The route to the summit of Penygadair includes a variety of terrains, from rocky paths and moorland to wooded areas and steep, uneven ground. The path is well-defined but can be challenging in places, especially in the higher sections, where it’s necessary to climb over rocks or navigate through boulder fields. The total ascent of 1122 meters means the hike is strenuous, but it’s achievable for those who are physically fit and prepared for a challenging mountain day.
The final stretch to the summit of Penygadair involves a rocky ridge with loose stones in places, making it important to take your time and ensure solid footing. There are also some exposed sections, where the views are breathtaking but require careful attention to your footing.
Fitness Level:
This is a challenging, full-day hike that involves steep ascents and rocky terrain, so a good level of fitness is required. It’s ideal for walkers with experience in mountain hiking, as the route involves sustained uphill sections and requires a bit of stamina. The terrain is rugged, and some sections may feel strenuous, but with determination, you’ll be rewarded with some of the most spectacular mountain views in Wales.
