From the ridge between the summits of Cyfrwy and Cadair Idris there is an impressive view of the lake Llyn y Gader deep down under the cliffs. Watch your step, though, and stay away from the edge - some of the rocks and stones may be loose.

Cadair Idris summit trig point

Highlight • Natural Monument

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.

Penygadair summit, Cadair Idris

Highlight • Summit

Complex and striking, Cadair Idris is the Yr Wyddfa (Snowdon) of southern Eryri (Snowdonia): a honeypot mountain renowned for its imperious cliffs, enticing ridges and pretty tarns. It is a peak shrouded in myth. Its name, meaning ‘Chair of Idris’, derives from the Welsh legend of a giant who created a mountainous seat for stargazing.

Summit shelter on Cader Idris

Highlight • Mountain Hut

Just below the rocky summit stands a sturdy stone hut. It is a modern version of a 19th-century hut that became famous through an old lady who climbed to the summit early in the morning and offered a cup of tea (paned o de) to everyone who passed by. "Paned o De" is said to be the name of this shelter.
