 It can be walked across and viewed from across the valley.There is car parking at the bottom of the valley at Ponts Mill which is just off the A390 road at Porcupine, or at the top of the valley just north of the Treffry Viaduct, where there is a junction.There are also many walks to the viaduct from St Blazey village and from Luxulyan railway station on the Newquay branch line which passes beneath the viaduct.
