Builth Wells Cycles offers guided rides in the Cambrian Mountains, probably aimed more at the experienced mountain biker with a taste for the off-road route.
The areas covered include the Cambrian Mountains, the Elan and Wye Valleys and the Radnor Forest.
If you don't fancy the off-road option, you can just hire a bike and explore the countryside under your own pace. As well as bicycles of all types, the company also has tag-along and buggies available for hire.
It is advisable to book in advanced for guided rides. Discounts are available for group bookings.
