Imagine yourself in Montana's Big Sky Country, in the untamed place where the Rockies meet the plains. It's twilight, and you're cozied up in front of the fireplace after a day spent practicing yoga, exploring by horseback and getting a deep tissue massage. From inside your secluded tree house you notice a deer wander past, unrushed in her search for a snack of wildflowers. Soon you'll be enjoying your own dinner sourced from the landscape, beginning with freshly-caught roasted rainbow trout and ending with ice cream that's infused with minty spruce tips. And tomorrow? Who knows. Maybe you'll rappel down the face of a mountain.

These experiences, and so many more, await you at the green o resort, opening soon in rural Montana. Sitting at the southern edge of the renowned Paws Up Ranch, and within some 37,000 acres of wilderness, the green o is a serene, adults-only addition to this spectacular place. The resort itself isn't particularly easy to spot; its twelve nordic-inspired Haus accommodations are tucked away in the woods, each offering the ultimate in comfort, privacy and sustainability. All were built to integrate with their natural surroundings as seamlessly as possible, and not a single tree was cut down during construction. Floor-to-ceiling windows are featured in each of the four Haus designs, as do fireplaces and private outdoor hot tubs.
