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.

The Minffordd Path (Welsh: Llwybr Minffordd) starts on the south side of the mountain, near the glacial lake Tal-y-llyn. Hikers following this route climb past Llyn Cau and along the edge of Craig Cau (a rock face) to Penygadair. The route is 4.4 kilometres long and includes two ascents of over 300 metres. (Wikipedia)

Crib Goch is a super “exciting” Grade 1 scramble, but it is important to know your abilities and manage the risks of traversing this amazing ridge. Crib Goch is one of the best ridges of its kind and grade anywhere in the UK. It has great scrambling, with some famous arete sections. On a grade one scramble you will need to use your hands on the rock, and on Crib Goch you will do this often. Traversing the ridge on a sunny day is a marvellous experience; on a cold winter day, or in bad weather, it can be perilous without the appropriate equipment. While often straightforward, Grade 1 scrambles still carry risk due to height and exposure, and they should not be taken for granted, especially in poor weather.

A very fine mountain that is the high point of the Carneddau range. These mountains are high, remote and so much quieter than the Glyderau or Snowdon. Fabulous walking country.

Gwynedd offers a vast network of over 1,100 running routes. These trails traverse diverse landscapes, from the challenging mountain paths of Eryri (Snowdonia) National Park to the scenic coastal stretches and tranquil lakeside loops, catering to all fitness levels.
Runners in Gwynedd will encounter a wide variety of terrain. Expect everything from rocky mountain paths and sharp ridges in Snowdonia, such as on the Pyg and Miners Track loop, to grassy ridges, forest trails, and gentle lakeside paths like the Llyn Padarn Loop Trail. The Wales Coast Path sections offer invigorating runs along sandy beaches, rugged cliffs, and wild heathland.
Yes, Gwynedd has plenty of options for less experienced runners or those seeking a relaxed pace. Approximately 90 routes are classified as easy, offering gentler gradients and less technical terrain. The Llyn Padarn Loop Trail, for example, provides a moderate, scenic lakeside run near Llanberis.
For experienced trail runners, Gwynedd, particularly within Eryri (Snowdonia) National Park, offers numerous challenging routes. These often involve significant elevation gain and technical terrain. Examples include the Pyg and Miners Track loop on Yr Wyddfa (Snowdon), the Snowdon Summit loop, and the Minffordd Path Cadair Idris Loop, all featuring substantial ascents.
Absolutely. Many of Gwynedd's running trails are designed as circular routes, allowing you to start and finish at the same point. This is particularly common around lakes and in mountain areas. For instance, the Moel Eilio loop from Llanberis and the Carnedd Dafydd & Carnedd Llewelyn loop are excellent circular options.
Yes, Gwynedd boasts a significant 180-mile section of the Wales Coast Path, offering fantastic coastal running opportunities. These routes provide diverse landscapes, from small coves and long sandy beaches to rugged cliffs and wild heathland, particularly on the Llŷn Peninsula. The Around Mynydd Tir-y-Cwmwd Run at Llanbedrog Beach is a great example of a route combining coastal scenery with woodland paths.
Gwynedd's routes are rich in natural beauty and historical landmarks. You can run past stunning lakes like Llyn Llydaw and Llyn Glaslyn, or discover impressive waterfalls such as Aber Falls and Rhaeadr Ddu (Black Falls). Many trails also pass through the UNESCO World Heritage Slate Landscape, featuring former quarries and historic sites like Plas Cwm Llan Ruins.
The running routes in Gwynedd are highly regarded by the komoot community, holding an impressive average rating of 4.6 stars from over 170 reviews. Runners frequently praise the breathtaking mountain and coastal scenery, the variety of terrain, and the well-maintained trails that cater to all abilities.
Many trails in Gwynedd are dog-friendly, especially those in less sensitive areas or on public footpaths. However, within Eryri (Snowdonia) National Park, it's crucial to keep dogs on a lead, particularly during lambing season (spring to early summer), to protect livestock and wildlife. Always check local signage and respect the countryside code.
While many mountain trails are challenging, Gwynedd does offer family-friendly options. Routes with flatter, wider paths, such as sections of the Wales Coast Path or some forest park trails like those in Coed y Brenin, can be suitable for families. For pushchair-friendly routes, look for paved or very well-maintained gravel paths, as most natural trails will be too uneven.
Spring and autumn are generally considered the best times for jogging in Gwynedd, offering milder temperatures and often clearer skies, ideal for enjoying the stunning landscapes. Summer can be pleasant but also busier, especially in popular areas like Snowdonia. Winter running is possible but requires appropriate gear for potentially cold, wet, and icy conditions, particularly at higher elevations.
Absolutely. Gwynedd is renowned for its spectacular views. Many routes, especially those ascending mountains or following coastal paths, offer incredible panoramic vistas. For example, the Yr Wyddfa (Snowdon) Horseshoe loop provides expansive views of the Snowdon massif, while the Precipice Route near Dolgellau offers stunning outlooks over the Mawddach Estuary and surrounding mountain ranges.
