A steep and relentless pull up from Ogwen Cottage to the gateway of the Carneddau. It offers staggering views across the Ogwen Valley to the Glyderau.

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.

A wonderful spiky summit with fine views to Yr Wyddfa and into Ogwen Valley. The summit itself is a scramble over very large jumbled boulders.

Y Garn is a fine hill, usually climbed from Ogwen Valley by it's West ridge, or as part of the walk along the Glyders range between Elidir Fawr and the Glyders themselves. There is however another way up, the East Ridge, which is a Grade 2 scramble and starts from Llyn Idwal.

The high pass between Tryfan and Glyder Fach is also a crossroads for a number of paths - down to the Ogwen valley, but also up to Tryfan and to Glyder Fach via the Bristly Ridge or the bypass route.

Generally, dogs are welcome on trails in Eryri National Park (Snowdonia), but it's crucial to keep them under close control, preferably on a lead, especially near livestock. Always follow the Countryside Code. Specific restrictions might apply in certain areas or during lambing season, so it's best to check local signage or the park authority's guidelines before you go.

The best time to go running in Llyn Ogwen largely depends on your preference and experience. Spring and autumn offer cooler temperatures and stunning scenery with fewer crowds, though weather can be unpredictable.

Winter running is possible for experienced individuals, but requires appropriate gear and caution due to potentially harsh weather, ice, and snow on higher elevations.
While popular routes like the Llyn Ogwen Circular Walk can see more visitors, exploring some of the longer, more challenging mountain loops, such as the Y Garn to Glyder Fach trail running loop, might offer a more solitary experience. Early mornings or weekdays outside of peak season are generally the best times to find quieter trails throughout the region.
