     South Wales Caves


Rich and I headed over to Wales, pretty much knowing that the weather would not be in our favour to dive, so we were still committed to taking photos at our surface sites.

Rich photographs the Mellte at Ystradfellte Church Sinks

The water levels were indeed well up and there was hardly another soul in site. It was a grey, misty and damp day with poor light. We noted lots of rusty old fencing along the riverbank and did not see a single creature all day. Most were wisely tucked up for the winter.
