Lyman Lake CG, Okanogan NF, WA This campground was a challenge to find! It is located in northeastern Washington near the southern boundary of the Okanogan National Forest, just north of the Colville Indian Reservation. One of our maps showed its location; another did not. Using our GPS unit in conjuction with USGS topographical maps loaded into our laptop computer, we navigated to the indicated location. There was not a single sign on any of the roads indicating this campground still existed. But it was there - complete with a clean outhouse with toilet paper!! And it was free! Needless to say, we were the only campers.
