The late Alan Coase was a leading contributor to the scientific study and exploration of the cave in the 1960s. This was an exciting period with the passing of the Long Crawl and the discovery of the spectacular passages beyond. These pictures date mostly from that period and show many of the people involved and the techniques in use at the time. Sadly, a number of the slides were in poor condition and restoration work is needed on the scanned images. They are reproduced here "as is".
Scheduled as a Site of Special Scientific Interest (SSSI), Dan Yr Ogof is afforded a special level of protection under the Wildlife & Countryside Act (1981). The Dan Yr Ogof Conservation Advisory Panel works with the showcave management team to administer the wild cave that lies beyond the showcaves. Conservation of this unique cave is the primary aim of the panel. Exploration and access to the cave is controlled by the panel working with a team of conservation wardens who accompany the caving trips beyond the showcave.
People wishing to visit the Dan Yr Ogof Showcaves visitor attraction should consult the showcaves website.
