Porth Ferin is a small bay backed by a steep grassy bank, on the opposite side of the Penrhyn Mawr headland to Porth Iago, and can be reached along the same lane. There is some space for roadside parking in this lane just after the turning for Porth Iago, but care must be taken not to cause obstruction to farm vehicles. There is no parking space further down the lane.
At the end of the metalled lane, a public footpath follows the track straight ahead. This leads to a gate with a sign saying 'Private - No parking'. The public footpath continues through the gate and turns right immediately after a (derelict) building on the right. A short distance ahead is a field gate which opens onto the coastal path. Access to the beach is down the slope at the rear of the beach.
