A multi-million pound national climbing centre which fell into administration is to reopen after a major refit.
The centre is reopening after a £6m overhaul
The Edinburgh International Climbing Arena (EICA): Ratho has undergone a £6m overhaul since the city council bought it in October 2005.
It originally opened as the world's biggest indoor wall in 2003 at the cost of £30m but fell into administration.
Edinburgh Leisure, which runs the centre, said it hoped the new investment had secured its future.
The huge centre, which is built into the side of a quarry near Ratho, closed in August 2006 to allow full completion of the venue.
It reopened to climbers in February this year but the whole centre has now been completed and is due to open on Friday.
The new management said that along with providing a world-class climbing arena, the centre now offers a variety of other facilities in the hope of making it economically viable.
It hopes to become a successful conference centre for businesses and a live music venue.
It also aims to entice a broader range of visitors by catering for the young, families and tourists.
Keith Jackson, chief executive officer of Edinburgh Leisure, said: "We are committed to providing diverse and exciting leisure opportunities for all.
"The enhanced EICA: Ratho is a fantastic resource to hone the skills of Scotland's future climbing champions, but also to introduce people of all ages and abilities to an exhilarating leisure pursuit.
"In addition the EICA: Ratho encompasses a huge range of facilities outwith climbing."
The £6m overhaul included improving drainage to stop flooding in the main area and structural work on the vast roof.
A scuba diving tank which was never used has been converted into a "bouldering" facility.
A large area which had been intended as lodge accommodation has been refitted as a children's soft play area and a new spa has been built.
The car park, plumbing and electrics have also all been upgraded.
EICA: Ratho manager Graeme Gardiner said: "A huge amount of work has gone into getting the EICA: Ratho ready for the re-opening and we are all absolutely delighted with the results."
The centre houses the world's largest indoor climbing arena with three climbing walls and an aerial assault course.
To mark the reopening the centre is holding an open weekend across the bank holiday.
