Porthdinllaen marine walk on the Llyn Peninsula Details

Porthdinllaen is one of the most well known scenes on the Llyn Peninsula. Not only is it scenic, but there’s even a pub right on the beach. The only downside is that it can be a honeypot in the holidays so get there in the off season to really appreciate it.
