Kraig Adams makes beautiful and soothing documentaries about his hiking alone on scenic trails, like this 70-mile hike on the Sawtooth Loop Trail in Idaho.
With just a touch of quiet music underneath the nature sounds, and the occasional drone shot, these are a very relaxing way to spend an afternoon working. They're great for watching as you're going to sleep, too. He says, "I hope to bring a kind of stillness and calm to you while watching at home." Here's a recent one from Alaska.
He's also been to South America, Japan, Icealnd and Nepal (below).
