I'm headed to Pembrokeshire on Sunday and wanted to grab some footage of the Welsh 'Green Bridge'. A rock formation on the coast. I know a lot of the coastline is National Park, but is this National Trust property? I understand that the National Trust are difficult to get permissions off of, and seeing as I'm currently renewing, I can't supply them with a still-in-date PFAW or BNUC for the next few weeks. So yeah, national parks...are they run by the National Trust?
