SOME of the world's top climbers will scale the three 55-storey glass towers of Marina Bay Sands (MBS) when the integrated resort officially opens on Wednesday.
The 21 climbing enthusiasts from all over the world will scale the 200-metre high facades of the resort in a relay contest called the World Championship Climb.
Many of these climbers are more accustomed to climbing rock walls and mountains than they are on glass buildings.
