Oman today_ The iconic selfies taken on this unique cliff in Norway often appear on the Instagram or Pinterest feeds of adventurous travelers. The rock juts out from the mountainside like a giant tongue, and standing on its edge feels as if you’re suspended in the sky. Those who endure the long hike and hours of climbing are rewarded with breathtaking views of the lake below and Norway’s largest glacier in the distance. However, if you’re afraid of heights, it’s best not to venture too close to the dramatic edge of Trolltunga.
