Paws Up Montana Green O Tree Haus

The Tree Haus sits among Paws Up Montana's Green O collection, one of twelve glass-walled dwellings raised into the pines above the Blackfoot River valley in Greenough. Built for couples, the adults-only Haus pairs forest views through floor-to-ceiling glass with a private hot tub set on its own deck, so the line between inside and outside all but disappears.

The ranch around it covers 37,000 acres of working cattle country, laced with more than 100 miles of trails and bordered by ten miles of the Blackfoot River, giving guests direct access to water and backcountry alike. A full kitchen inside the Haus means meals can happen on-site, though the resort also runs its own dining program for those who'd rather not cook.

Paws Up markets the Green O toward couples looking to unplug, and the wider resort's scale also supports remote work and larger gatherings elsewhere on the property if a trip expands beyond two people. Pets aren't permitted in the Tree Haus.

Reservations run through the resort directly, by phone at (800) 210-6445 or online at pawsup.com; rates and minimum-stay requirements should be confirmed there, since the property sits at the top end of the luxury tier without posting fixed nightly prices.
