High Quality Content by WIKIPEDIA articles! SnOasis is a controversial proposed indoor winter sports resort in Great Blakenham near Ipswich, Suffolk currently scheduled to open in `late 2014`. It is planned be the largest real snow indoor ski slope in the world with a 415 metres slope long, 70 metres wide run and a 100 metres drop accommodating 1000 skiers per hour. There are several comparable slopes, including one at Neuss, Germany, but none have a vertical drop of 100 meters and the overall ski area of SnOasis will be more than double that of any other indoor ski slope in the world.
