Cadair Idris loop on the Minffordd path — Eryri / Snowdonia National Park

The Cadair Idris loop on the Minffordd path offers a challenging hike, covering 6.5 miles (10.5 km) with a significant elevation gain of 2776 feet (846 metres). You can expect to spend around 5 hours and 8 minutes on this difficult route. It begins with a steep climb through the wooded gorge of Nant Cadair, where you will see impressive waterfalls. The path then opens up, circling the dramatic glacial lake of Llyn Cau, nestled beneath towering cliffs. As you ascend towards the summit, Penygadair, you'll get glimpses of the peak and eventually be rewarded with panoramic views across southern Snowdonia and the coast.

This difficult route requires a good level of fitness due to its consistent steepness. While the path is generally easy to follow, some sections are very steep and can be tricky, with loose rocks underfoot. Be prepared for a demanding hike, and note that navigation skills are essential for certain parts of the trail. Always check local conditions before you go.

The Minffordd path is celebrated as one of the most picturesque routes up Cadair Idris, offering diverse landscapes from ancient woodlands to expansive mountain vistas. Cadair Idris, meaning "Idris's Chair," is steeped in Welsh mythology; legends say anyone spending a night on the peak will wake up a poet or a "madman." This trail also provides a less crowded experience compared to other peaks in northern Snowdonia, making its challenging ascent even more rewarding.
