TORONTO - The CN Tower's latest attraction, which allows daredevils to take a stroll 356 metres up in the air, opened to the public Monday.

EdgeWalk lets thrill-seekers take a hands-free walk along a 1.5-metre-wide ledge around the top of the tower's main pod.

Walkers get suited up in fire engine red jumpsuits and yellow harnesses and venture out in groups of six to eight for a stunning, open-air view of Toronto and Lake Ontario.

They're accompanied by trained guides.

Safety harnesses and industrial-strength cables attach walkers to an overhead rail, allowing them to lean off the edge of the platform and gaze out on the city sprawling below.

The experience costs $175 and lasts a total of 90 minutes, with the walk itself taking 20 to 30 minutes.
