The Minffordd Path Cadair Idris Loop offers a difficult jogging challenge, covering 5.8 miles (9.4 km) with a significant elevation gain of 2601 feet (793 metres). You can expect to complete this demanding route in about 2 hours and 1 minute. As you ascend, you'll pass through ancient woodlands and alongside the impressive waterfalls of Nant Cadair Gorge. The trail then circles the stunning glacial lake of Llyn Cau, nestled dramatically within a bowl-shaped depression. From higher up, panoramic views stretch across Eryri National Park, making the effort worthwhile.
Be prepared for a very steep initial ascent on the Minffordd Path, which features rugged and uneven ground. This includes sections of loose scree and numerous steep steps, so sure-footedness is essential. While some parts might be runnable, many sections will require walking due to the gradient and technical terrain. A good level of fitness is crucial for tackling this difficult loop. Consider starting early to allow ample time and to enjoy the views before crowds gather.
Cadair Idris is a mountain steeped in Welsh mythology, often associated with a giant or a sleeping dragon. The name itself translates to "Idris's Chair," referring to a mythical giant. The dramatic landscape, shaped by glacial activity, contributes to the unique character of the trail, particularly around Llyn Cau. This route provides a memorable experience of one of Eryri National Park's most iconic peaks.

According to legend, Cader is named after a giant called Idris Gawr. 'Cadair Idris' means 'Chair of Idris' in English, while 'Cader' can also refer to an ancient fortress. The place is known as Cader Idris rather than Cadair, but both names are used. The most famous local fable is that if you spend the night on the mountain, you will go mad or become a poet.

A triangulation station, also known as a trigonometric point, or sometimes informally a trig, is a fixed measurement point used in geodetic surveys and other land surveying projects in the surrounding area. The station is usually established by a cartographic organization with known coordinates and published elevation data. Numerous stations are placed on mountain tops for better visibility and prominence. An engraved metal plate on top of a pillar can serve as a mounting point for a theodolite or reflector, often using a kinematic coupling to ensure reproducible positioning. (Wikipedia)
