Pão de Açúcar, Rio de Janeiro

Some say to come around sunset for the best views from this absurd confection of a mountain. But in truth, it doesn’t matter when you come; you’re unlikely to look at Rio (or your own comparatively lackluster city) in the same way. From here the landscape is pure undulating green hills and golden beaches lapped by blue sea, with rows of skyscrapers sprouting along the shore. The ride up is good fun: all-glass aerial trams that whisk you up to the top. The adventurous can rock-climb their way to the summit.
