Three explorers who discovered a new entrance to one of the UK's major cave systems have returned there to mark the 40th anniversary of that moment.
Two of them, now aged 62, retraced their steps through Ogof Fynnon Ddu, in the Swansea Valley, from a second entrance they uncovered in 1967.

The cave had been discovered in 1946 but a "through trip" was impossible.

Ogof Fynnon Ddu, meaning the Cave of the Black Spring, is the deepest and the third longest cave in the UK, according to Peter Collings-Wells of the South Wales Caving Club.
