20 mile walk - Self-guided

O Glyn 

Starting off easy, you will be able to enjoy the scenic farmland along The Cambrian Way. Once you pass The Arch / Y Bwa you enter the beautifully wild Ystwyth Forest and expect some steep climbs. 

Following the Ystwyth River down the Cwmystwyth Valley you will be able to enjoy the stunning scenery of the fords, waterfalls and a bounty of wildlife. Your challenge becomes harder with a steep downhill track, before you pass through farmland. Then you'll take a mighty valley climb enjoying spectacular views of the lakes of Devil’s Bridge before your final leg back to basecamp (Tynrhyd Retreat).


This route is suited for the more experienced walker, you will navigate yourself through the sweeping moorland and forest paths of the stunning landscape famous by the award winning S4C/BBC Wales TV detective series Y Gwyll/Hinterland.
