Ready for a proper Welsh adventure? Traws Eryri is Cycling UK’s challenging, mainly off-road crossing of North Wales, linking Conwy, Gwydir Forest, Betws-y-Coed, Penmachno Bike Park, Llyn Trawsfynydd Reservoir, Coed y Brenin, Cadair Idris and Machynlleth.
Route variants and test rides may show different totals, so always check Cycling UK’s latest GPX file and route guide before setting off.
Cycling UK’s route information gives approximately 196 km (122 miles) and around 3,828 m (12,560 ft) of ascent. Most riders allow 3–4 days, depending on fitness, weather, stops and route conditions.
Expect steep climbs, forest tracks, rough and rocky sections, plus some quiet roads. Experienced riders describe it as demanding but hugely rewarding, with outstanding scenery. This is not a beginner route: it is not continuously waymarked, so GPS navigation is essential, along with a suitable mountain bike, wide tyres, low gearing and a backup map.
On the Llyn Trawsfynydd and Coed y Brenin section, Rhiw Goch Inn is close by and offers a welcoming base for riders planning their Eryri (Snowdonia) adventure.
Pob lwc : good luck, and enjoy every hard-earned view! 🚵♀️🏔️
