The Three Rivers Resort is closest to the National Forest. Great little rustic cabins at a very reasonable rate with a relaxing porch overlooking the Lochsa River. If you don't mind rustic, or a little aged accommodation you'll be in for a pleasant stay. We stayed in cabin #3, there are 4 beds, wifi from the porch, TV and modest kitchenettes in the cabin. There is also RV sites which look pleasant and an onsite pool and spa.
Don't miss the dinner at the restaurant overlooking the river. The BBQ ribs are a do not miss with a delicious huckleberry BBQ sauce. YUM.
Of course the real attraction originating here on site is the River Rafting. They have a serious set of rafts to host big groups. What a great summer activity.
If you are heading up into this neck of the woods, this is a great choice for a stay.
