Embark on the Yr Wyddfa (Snowdon) circular, a difficult mountain biking route known as the "Classic Loop" in Eryri (Snowdonia) National Park. This challenging ride covers 11.5 miles (18.5 km) with a significant 3316 feet (1011 metres) of elevation gain, typically taking around 2 hours and 33 minutes. You will ascend the popular Llanberis Path, which features loose, rocky sections and steps, before tackling the highly technical Snowdon Ranger Path descent with its tight drops, loose rocks, and sweeping switchbacks, all set against a backdrop of rugged mountains and glacier-carved valleys.
When planning your ride, be aware of the Voluntary Cycling Agreement (VCA) on Yr Wyddfa. This agreement requests that you do not ride to or from the summit on the Llanberis and Snowdon Ranger paths between 10:00 and 17:00 from May 1st to September 30th. Outside these hours and between October 1st and April 30th, you have full access to these bridleways. Remember that you are legally required to give way to pedestrians and horse riders on all bridleways.
This circular route is considered an ultimate mountain biking challenge in Wales and a bucket-list ride for many experienced cyclists. The combination of a sustained, physically demanding climb and a thrilling, technical descent makes it a memorable adventure. The VCA demonstrates a collaborative effort to ensure access for cyclists while maintaining safety and enjoyment for all users within the national park.
