After my walk round the coastal path, I went to have a look at Porth Clais, as it would be a good place to launch from if heading off for a paddle around Ramsey Sound or Ramsey Island.
I don`t seem to have done very well - this is the only picture I took - it would have been a bit more useful to have taken some pictures of the harbour, launching point, etc.
As far as I can remember, there are quite a lot of parking areas, and from various sources, Porth Clais dries out somewhat at low tides, but not as badly as at Solva.
