Deep in the Ecuadorian Andes and some 12,000 feet above sea level, the Quilotoa Crater Overlook teeters over the edge of a collapsed volcano and the stunning Quilotoa Lake. The glass-fronted double platform is made from pre-weathered teak, designed to compliment and blend into its surroundings, and offers two viewpoints from either the top deck “producing an almost vertigo-like sensation” or the lower stairs, “a space for passive viewing.” A project from the Ecuadorian tourist board, the Quilotoa Crater Overlook supports the indigenous Shalalá community who run the area’s facilities and was designed by architects Javier Mera, Jorge Andrade and Daniel Moreno.

At the heart of the Canadian Rockies, the Glacier Skywalk jets out 30-metres from the cliff’s edge, above a 915ft drop to the ground. With a glass-bottomed floor, the Skywalk allows visitors a unique 360° view of the beautiful Jasper National Park, though you’ll need nerves of steel to look down. A steel and wood construction helps the walkway structure blends into its surroundings, with the project close to a zero carbon footprint. The Glacier Skywalk opened May 1st and will set visitors back $24.95, head to their site for more details: www.glacierskywalk.ca
