The first tunnel is the longest of the three on the way to Saundersfoot and now has the luxury of ground-level lighting powered by solar. It is still dark but at least you know where the edges are. Suddenly Coppet Hall beach and Saundersfoot appear in all their glory, discerning people will naturally favour Coppet Hall, much more classy!
When you emerge from the darkness just lean on the railings and stare towards the harbour and take yourselves back to 1846, in your minds eye you will see sailships in the harbour being loaded with coal, ships sailing out destined for far distant ports. You would be seeing fewer houses and everywhere would bear the colours of the coal industry. Incidentally there is no hall called Coppet Hall so why that name? Well in the early days of mining the produce of the various mines between this beach and beyond St Issells church was brought here and loaded on to ships at low tide. The name Coppet Hall is a much nicer way of saying 'coal pit haul'.
So there you are!
Incidentally the information I am given you here is gleaned from an excellent book by Thomas G Stickings called 'The Story of Saundersfoot' which is available from Abe Books.
