WATCH: Drone footage reveals scale of huge Horseshoe Pass fire
Dramatic drone video footage has revealed the scale of a blaze that has been burning for more than three weeks.
It was open, then it closed, then it opened again and now it is closed again.
The fire that has burned over the Horseshoe Pass near Llangollen looks set to continue into another week.
North Wales Police has now released video footage of the blaze showing the huge extent of the fire and miles of blackened moorland.
WATCH the drone footage:
The road leading over the pass was re-opened earlier this week, however at 5.30pm on Thursday the road was closed yet again as six crews carried on putting out hotspots.
The public were again reminded to stay away from the mountainside and North Wales Fire and Rescue Service said its crews were working in difficult circumstances and dealing with hotspots and fire around the Ponderosa area.
An update provided shortly after 5.30pm stated that the Horseshoe Pass Road was closed.
Fire crews from across north Wales have been working around the clock to fight and damp down the hillside blaze. It began on the Llantysilio mountain on July 18.
There have been three incidents of the fire service's 4x4 vehicles overturning on the steep hillside as crews tried to reach the more inaccessible areas. None of the firefighters suffered serious injuries.
Shropshire fire crews have occasionally stepped in to help as relief crews.
More that 600 acres of land have been damaged in the fires which for a time meant the closure of the popular Ponderosa Cafe on top of the Horseshoe Pass amid fears the fire and smoke could engulf the site.
Natural Resources Wales has said the extent of the damage to wildlife caused by the fire is unprecedented.
Nick Thomas, north east operations manager for NRW said: “Over the last five years NRW, Denbighshire County Council, local farmers and others have worked hard trying to improve the vegetation of Mynydd Llantysilio for wildlife and grazing.
“This benefitted rare species like black grouse and curlew.
“It is really sad to see the vegetation go up in flames and the efforts made to improve the common lost, it could take decades for it to recover.”
