If you're visiting the Czech Republic, may we suggest a detour to this architectural marvel: a terrifying walking platform that looks like a rickety roller coaster.
Built by local firm Fránek Architects, the 55-meter high wooden and steel structure was grants the bold with 360-degree views of the Morava river and Krkonoše Mountains.
The tourist attraction opened in December last year, and stands sentinel at the summit of the Králický Sněžník mountain, 1116 metres above sea level. For visitors brave enough, the structure features a mesh net section that you can walk on, lie on top of, or assume the foetal position on while begging someone to rescue you.
As good as the walk looks, the best bit has got to be the 100-metre tall slide that takes you back down to the bottom.
