Select participants and date
The journey begins as the castle walls of Cardiff slip into the rearview and the city’s sea breeze gives way to hedgerows, valleys, and high sheep-dotted ridgelines. This is a route that coaxes you to slow down. Rivers hustle you upstream, cloud shadows run over the hills, and the road threads toward the spine of Wales where mountains push the horizon higher with every mile.

Adventure Tips
Book the Snowdon Mountain Railway early
Seats sell out in peak months—reserve weeks ahead if you plan to ride instead of hike.
Fuel up before rural stretches
Petrol stations thin out in the Cambrian Mountains and late evenings; top up in market towns.
Master single-track etiquette
Use passing places, keep left, and wave thanks; expect sheep and cyclists around blind bends.
Pack for four seasons in a day
Waterproof layers and warm midlayers are smart year-round in the Beacons and Eryri.

History
Slate quarrying around Blaenau Ffestiniog once roofed the world; today the UNESCO-recognized Slate Landscape tells that story across mines, railways, and villages.
Conservation
Much of the route crosses national park and water catchment land—stick to paths, keep gates closed, and leave no trace to protect peat and fragile uplands.
