The Glyderau mountain range stretches from Mynydd Llandegai to Capel Crig, with some of the highest peaks in Wales.
The Glyderau (a Welsh plural form, also known in English as the Glyders) are a mountain group in Snowdonia, North Wales. The Glyderau stretch from Mynydd Llandegai to Capel Curig, and include five of Wales' fourteen or fifteen summits over 3000 feet; these include Tryfan, considered one of the finest mountains in Wales and one of the few mountains on the British mainland requiring scrambling to reach the summit. The highest mountains in Wales are in Snowdonia and include Snowdon (Welsh: Yr Wyddfa) which, at 1,085 metres (3,560 ft), is the highest peak in Wales. Glyder Fawr is a mountain in Snowdonia, Wales, the highest peak in the Glyderau range at just over 1,000 metres, having had its height recalculated in 2010 using GPS. It is the fifth-highest mountain in Wales and has several walking and scrambling routes leading to its summit. Glyder Fach is a mountain in Snowdonia, north-west Wales, and is the second highest of the Glyderau and the sixth highest in Wales. The name derives from the highest peaks in the range, Glyder Fawr and Glyder Fach.
