The Weltballon HiFlyer (also: HighFlyer ) is a filled with helium large captive balloon, which can ascend a few hundred meters. However, it remains connected via a cable always connected to the ground and is pulled from there by means of a winch. It serves as a public attraction, because at the highest point offers a wide view over the surrounding countryside. The viewpoints, which are particularly popular with tourists, were first set up in 1993.
