And there's a quiet carpark nearby if you arrive late...

Was the same when we were down there Xmas/new year couple of years back....I answered a similar question on the WC forum with this:-
"It's Pembrokeshire. They hate motorhomes and send rangers out hunting (yes, really) so WC is almost impossible. Sorry"
You used to be able to overnight on the harbour at Porthgain but not anymore. Likewise on the beach by Blue Lagoon with £10 to the local community fund but that's been stopped now.
Sad times.
We have stayed at Strumble Head a few times. Very picturesque and quiet but you need to navigate some narrow roads. We have a 7.5 metre van so it’s no real problem .Can anyone recommend a wild spot near St davids
