In terms of size, the reversible aerial tramway installed by the Doppelmayr/Garaventa Group in the Ha Long Bay in the north of Vietnam puts all previous ropeways in the shade. Each of the two cabins can accommodate 230 passengers and the 188.88 m high tower is the highest ropeway tower in the world.  More or less the entire ropeway, which was ceremoniously opened on 25 June 2016, comes in size double XL.
