A flat route most of the way, this is a family friendly and easy walk, however keep an eye out for cyclists when returning on the forest road/cycleway. Beginning at Rhyslyn car park, descend onto the path, following the Afan River upstream. The path gently hugs the riverside and meanders sporadically into shaded woodland for the first half of the walk, offering plenty of opportunities to admire the many tranquil beauty spots along its course. Upon reaching the wooden footbridge there is a quick ascent before veering left and heading back down to Rhyslyn along a disused mineral railway track, enjoying river or mountain views either side. The return route touches briefly on St. Illtyd's Walk, a long distance route commemorating the late 5th / early 6th century Welsh saint. The 103km route links Pembrey Country Park, in Carmarthenshire, with Margam Park in Neath Port Talbot.

Wildlife Watching: In the woodlands look out for birds such as Siskins and Goldcrests. In the open areas look out for butterflies such as Green-veined White and Ringlet.
