Planning approval has been granted for the £50 million Leisuredome to be built in Weston-Super-Mare.
The facility will be set on a 12.7-acre site at Locking Parklands, a former RAF site in Weston-Super-Mare, and will boast a 210-metre ski slope - the longest in the UK.
The Leisuredome will also house an indoor climbing centre with a 40 metre climbing wall, the tallest in the world, alongside an indoor surfing centre and sky-diving facility. It will also support the local community with fitness and meeting facilities, including a children's centre, BMX skateboard park and gymnasium.
The development will be a major economic and leisure boost for the West Country and for the town of Weston-Super-Mare. It will deliver employment-led regeneration in an area where there is long term unemployment and provide a direct investment of £50 million to the town.
Clive Hamilton-Davies, director, Leisuredome (UK) Ltd, said: "We estimate it will attract 550,000 visitors in the first year, which will add to the £369 million already generated by tourism in the local economy every year."
It is hoped that work will commence as early as December this year and the facility will open in early 2013.
