The Coed Morgannwg Way, the Ogwr Ridgeway Walk and the St Illtyd's Walk long-distance paths all begin/finish around Mynydd y Castell within Margam Country Park. An inland section of the Wales Coast Path runs through the park along the escarpment above the motorway, and there are a number of shorter (less than three miles (5 km)) walks waymarked in the park. There are no major rivers in the park, but there are lakes and ponds, and it is possible to fish some of the ponds.
