May 11, 2026, Penygadair Summit, Cadair Idris

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.

It is worth the effort. At the top, you enjoy a beautiful view in all directions. It cannot be captured in photos.

Craig Cwm Amarch is separated from Cadair Idris by a short, narrow ridge around Craig Cau, which encloses the beautiful lake Llyn Cau.

The Devil’s Kitchen, known in Welsh as Twll Du ("Black Hole"), is a massive, dark crack in the basaltic cliffs of Clogwyn y Geifr, towering over the southern end of Llyn Idwal. Why the Name? It earned its English nickname because of the plumes of mist or steam that frequently rise from the chasm. To early observers, this looked like smoke rising from a chimney, leading to the legend that the Devil was busy cooking inside. The Experience The Path: A steep, rocky "staircase" of boulders leads you from the lake shore up toward the Kitchen. It is a strenuous climb that requires sure-footedness, as the ancient rock is often wet and slippery. The Scenery: As you ascend, you pass the Devil’s Appendix (the waterfall mentioned earlier) and gain incredible views back over the Cwm Idwal "amphitheatre." Geology: The area is a world-class geological site. You can see the Idwal Syncline here—a dramatic U-shaped fold in the rock layers caused by tectonic pressure millions of years ago. Botanical Rarety: The humid, sheltered environment of the Kitchen is one of the few places in the UK where rare arctic-alpine plants, like the Snowdon Lily, have survived since the last Ice Age. Once you reach the top of the Kitchen, the landscape flattens out into a high plateau containing the small, eerie lake of Llyn y Cŵn.

January 9, 2026, Afon Idwal Waterfall

Rhaeadr Idwal is the scenic waterfall formed as the outflow of Llyn Idwal tumbles toward the Ogwen Valley. Cascading over ancient volcanic rock, it is a highlight of the approach path from Ogwen Cottage. Nearby, the Devil’s Appendix plunges 93 meters down the cliffs of Twll Du, making it the tallest single-drop waterfall in Wales. These falls are most dramatic after heavy rain or when frozen into spectacular ice columns in winter.

January 9, 2026, View of Llyn Idwal

Llyn Idwal is a stunning glacial lake nestled in the Glyderau mountains of Eryri (Snowdonia), North Wales. Designated as Wales’ first National Nature Reserve, its dramatic landscape was famously studied by Charles Darwin to prove glacial action. Legend says the lake is named after a drowned prince and that birds refuse to fly over its crystal-clear waters.
