These two red singletrack descents are part of the larger Penhydd trail from Afan Forest Centre. First up, Sidewinder takes you through the woodland on a rocky, narrow trail with a few loose corners. Then you're straight into Dead Sheep Gulley, a more open trail that cuts across the moorland landscape with a bit more pedalling than the last section.
