10 Thrill-Inducing Activities Around the World

Scared of heights? Time to conquer that fear. At BridgeClimb Sydney, participants summit the arches of the Sydney Harbour Bridge on hikes that last up to three hours. Climb ladders and walk on catwalks, uneven surfaces, and through narrow passageways as you ascend to the top. The tours take place in all weather conditions, day and night, so come prepared for anything. Interested in making the experience extra special? Pop the big question to that special someone at the summit, 440 feet above the harbor. Talk about an adventurous proposal!
