Would you dare to walk on the clouds? If so, you can do just this in Dolní Morava in the Czech Republic. Sky Walk is a 55-metre high attraction resembling a classic Big Dipper rollercoaster and located some 1,100 metres above sea level. From the top, you get to enjoy spectacular views over the Morava river and beyond, as well as the chance to slide back down by toboggan. Zdeněk Franek is the architect; Taros Nova the designer.
