Route Information

If a quiet ride passing through a hidden jem within Wales is your idea of a perfect ride then this ride heading up the Towy and into the Cothi valley will be a ride you will remember for a long time.

Llandovery is a town where rivers play a huge part with no fewer than 4 rivers that pass through the town. The biggest of them is the River Towy, which is one of the longest rivers in Wales and the longest that stays entirely within Wales with the source within the Cambrian Mountains to the North and entering the sea at Llansteffan.

After leaving Llandover the route follows the path of the river upstream with views of the rapids that flow, deep channels in the rock and fantastic bridges that are dotted throughout. It is a pleasant and gentle ride through Cilycwm and up to Towy Bridge, the point at which the ride begins to change and where it leaves the Towy and heads into wilder landscapes.

The road climbs gradually and while it never reaches lofty heights, the type of road and quietness makes it feel higher and wilder. From the highest point of the route it starts to follow the River Cothi, a much smaller river that eventually flows into the Towy near Carmarthen and the valley that holds views throughout the journey downstream. As the road flows downhill, crossing the river on a few occasions and through ancient woodlands it passing Dolaucothi, a national trust site where a former Gold Mine that dates back over 2000 years to the era of the Romans. It is a great family friendly location to visit with caves to explore and gold that can be found.

From Dolaucothi, near Pumsaint the route rejoins wider roads for a short section and one major climb before pealing off soon after the descent starts back onto quieter roads. Passing through the village of Porthyrhyd marks a point at which the road starts to point downhill and is almost all the way back to Llandovery. A twisting, rolling descent that starts with views over to the Brecon Beacons, through small woodlands and finishes by crossing the River Towy once again with just the final mile back to Llandovery to follow. A fantastic ride for those that love exploring the wilderness.
