6Carrick-a-Rede Rope Bridge, Northern Ireland

The Carrick-a-Rede Rope Bridge links the mainland of Northern Ireland to a tiny island once used by salmon fishermen.

At 20 meters (66 feet) long and 30 meters (98 feet) above jagged rocks and crashing waves, the bridge sways dramatically in the wind. Its handrails and wooden slats make it safer today than in centuries past, but the sheer exposure to the elements ensures it remains a heart-stopping experience.
