Salmo-Priest Divide Loop Professional Review and Guide
"Along the northern Washington and Idaho border there are still mountains with vast old-growth rain forests. This is the wild homeland of the endangered mountain caribou, the Canada lynx, and the grizzly bear.
Going clockwise, take well-marked Trail 506 down toward the South Salmo River. You drop immediately and follow well-constructed switchbacks down through an increasingly beautiful old-growth forest to the river. There are plenty of springs and small creeks. You wind down among huge Douglas fir, white pine, and western red cedar. Some are more than 1,000 years old. The understory consists of many kind of berries, devil’s claw, ferns, carpets of moss, and many more species. The high-elevation beginning of this trail may cross deep snow under the trees in early to mid-July."
