The Nature Conservancy's Pine Butte Ranch. Hiking, riding, fishing, swimming, nature-watching, fossil-finding. It's sort of a Grizzly Bear preserve but you'd be lucky to see one - at a comfortable distance. Grizzlies do not like mountains - they like river bottoms and damp meadows best,
Even in summer, you can find snow and ice on the high hikes. June best for the wildflower bloom. That is like Eden. It's real America and, yes, there are firearms around. Europeans come there to experience the American West. My lad once got trapped in the outhouse by a Black Bear. Fire a couple of magnum rounds in the air and the bears run away.
The ranch lands abut the 1 million-acre Bob Marshall Wilderness. We all own that. They will give you a day-long trip to Glacier National Park too, if you want. Another astonishing wild place which we Americans own.
