Castle Valley, Utah, has to be one of the most stunning places on this planet. The scenery is beyond compare, and it’s admired by thousands every year. But Théo Sanson wasn’t content with just looking at these snow-swept peaks and valleys. Instead, he decided that he would much rather walk between mountains on a slackline.

Sanson’s stunt — and its gorgeous backdrop — are truly spectacular sights to behold.

Making it safely across to the other side is a miracle in itself, but I hope that Camp 4 Collective gives us a behind-the-scenes video soon. I mean, can you imagine the amount of planning that had to go into this?
