Shepp Ranch hasn't changed since Charlie Shepp built a cabin here in 1909. The wild Salmon River outside the cabin's door still has the best steelhead fishing on the planet. And hikers still spend days wandering this flank of the Gospel Hump Wilderness. But today, the ranch – 15 miles from the nearest road, and reachable by boat – is a no-frills, make-your-own-way guest ranch that limits visitors to 16 at a time. Lynn Demerse, its hostess, serves up garden greens and ham from her own stock. She says her butter is from Florence (a cow).

Getting there: From Boise, drive three hours to Riggins. A jet boat leaves daily at 11:00 a.m. to Shepp Ranch, where rooms start at $325.
