The death of two teenagers a year apart in the Brecon Beacons has prompted efforts to improve safety at the popular beauty spots.

Police, safety organisations, and the representatives of the Brecon Beacons National Park met on Tuesday following the death of the youths on adventure courses in the area.

Herve Bola's family said he could not swim

Their aim was to find ways of improving safety for groups after the two - Herve Bola, from Essex, and Jason Dalton, from Bargoed, south Wales - drowned in waterfalls just a few miles apart.

The safety summit considered putting up more warning signs and improving liaison between local tourist and rescue groups.

Herve Bola, 16, drowned on a visit to the Sgwd Gwladus falls - known locally as the Lady Falls - at Ystradfellte, near Glynneath in the Neath Valley, while on a course organised by a Herefordshire activities centre.

Eyewitnesses said he got into difficulty after jumping into the river to cool off.

He was pulled out of the water by a 17-year-old local boy and was pronounced dead at the scene.

Jason Dalton died just a couple of miles away

His death in July came almost a year after that of 17-year-old student Jason Dalton on a confidence-building course for young people.

He was dragged under by a whirlpool while trying to rescue his lecturer and another student who had been swimming in the swollen River Sychryd.

The accident happened while the group were on a walking trip to the Pontneddfechan waterfalls, also in the Neath Valley.

Both deaths led to calls for safety to be improved in areas where adventure courses are held and at some of the Beacons' most popular tourist haunts.

Trained supervisors

An inquest into Jason's death in August 2001 recorded a verdict of accident death but the coroner recommended that only trained supervisors should lead groups into the Pontneddfechan area.

Jason's family have indicated they may take legal action following the tragedy.

The Health and Safety Executive is deciding whether to bring charges over the death.
