Whilst enroute to our holiday inTenby we stopped over at Trecastle Farm listed as a CL site, we joined the Caravan and Motorhome Club so that we could stay here to meet up with a close friend and assumed it would have to meet a standard. We drove passed the site entrance due to lack of signage ending up down a very narrow lane with poorly trimmed bushes and trees each side resulting in all 6 side windows being badly scratched then we asked someone where the site was and had to go back up the lane resulting in more damage. Unbelievably we still couldn't find the site enterance and had to ask someone else, we eventually saw a caravan through an enterance into a field and this was the enterance with no sign. I raised the lack of signage with the owner/manager who informed us a tractor had knocked the sign off but when I asked why a temporary sign wasn't used he didn't give an answer. After assessing the damage to the 6 side windows we looked around the site in dismay the facilities are shocking. The EHU we used was in a small brick enclosure with a large crack in the roof allowing water ingress to the circuit breaker board on which the breaker cover is missing. The disposal facilities consisted of a few domestic bins. How have the Caravan and Motorhome Club certified this site, we can't believe we paid £56 to join so that we could stay here to meet up with a close friend and it's resulted in our campervan being damaged. We trusted The Caravan and Motorhome Club and boy have they let us down and ruined our holiday, all I want to do now is get home to see what can be done about the damage...🤬
