Porthgain is more of a harbour than a beach. Originally built to ship slate from Abereiddy and bricks from the brickworks at nearby St Brides quarries, it was served by a narrow (3' 0") gauge tramway. Much evidence of its industrial past is still apparent. Inside the harbour walls there's a fair amount of sand at low tide. Facilities at the small village include free parking (some overlooking the harbour), a pub and a cafe (both with outdoor seating), a slipway, toilets, a small shop and cycle parking.
