The Chepstow to Glasbury section of Route 42 forms part of fantastic the Lon Las Cymru route. There are a few challenging climbs on this route but you are rewarded with some fantastic scenery and awe-inspiring views.
Following the route out of Chepstow, the first section of the ride is on quiet roads and takes you through some lovely woodland before arriving at Usk.
The route then follows the River Usk towards Abergavenny on more country roads. At Abergavenny, you leave the river behind and head into the stunning Brecon Beacons National Park along quiet country lanes into the beautiful Vale of Ewyas, where it passes close to the ruins of the fabulous Llanthony Priory.
The route then heads to the hamlet of Capel-y-ffin, where it climbs Gospel Pass 542m (1,778ft) with spectacular views over the Wye Valley. From here, the trail drops into the Valley, where it links with National Cycle Route 8 at Glasbury.
There is a small loop at the top of Route 42 providing links to Hay-on-Wye which is well worth a visit.
