Pinnacle Camp, Greenough, Montana

If it weren’t for the pristine north-country wilderness just outside your canvas door—including the rushing waters of Elk Creek and the Blackfoot River; and the pine and aspen forests, where elk and white-tail deer roam—you might forget that Pinnacle Camp isn’t an opulent mountain lodge. How many American campsites come with their own jetted spa tubs, heated-slate bathroom floors, daily housekeeping service and a dedicated camp butler? In truth, Pinnacle’s six roomy tents are part of an opulent mountain lodge: The Resort at Paws Up, a 37,000-acre spread that includes a working cattle ranch, horse stables and hundreds of miles of wooded trails for hiking, riding and scouting a private fly-fishing spot. For roughing it, this sure feels smooth. From $1,055; pawsup.com.
