You’ve heard of Brighton. You know Blackpool. You’re probably familiar with Whitstable. Those are a few of the seaside towns that made it on to Time Out’s roundup of the 16 greatest in the UK right now.

Do you know, for example, Porthmadog? The ‘chilled-out’ north Welsh harbour town came in at number 13 on our coastal towns guide.
