Anyone afraid of heights would most certainly not be interested in exploring any of the 12 viewing platforms featured on this WebEcoist post. The most striking is probably the one shown, found at the Aurland Lookout in Norway. While it looks like a bridge solely made for suicides, it actually has a thick sheet of plate glass at the end to stop eager viewers from getting too close to the edge.
I think I would be willing to walk to the glass, but I would have to have my hand on the railing the whole time. Could you make it to the end of these beautiful but terrifying viewing platforms?
