Traveling into the far northern reaches of Maine, you’ll reach an area in Piscataquis County near the Canadian border. All of the local roads are privately operated toll roads, and the nearest major roads (Maine Routes 6 and 15 at Rockwood, Maine Route 159 at Shin Pond, and Quebec’s Route Provinciale 204) are at least 41 miles away. Perfect for a summer jaunt into scenic northern Maine.
Northwestern Nevada
A vast expanse in northwestern Nevada makes for a great hiking location for those who enjoy hiking in dryer areas. West of the Black Rock Range, the only major highway in the area is Nevada Highway 447, which is still 43 miles away (though sections of Nevada Highway 140 also pass by at a bit farther distance.) After all, 43 miles is still far enough to make this a great place to get away from it all.
Southwestern Idaho
Travel into the extreme southwestern part of Idaho, and you’ll find yourself in somewhat of a “No Man’s Land” in the area where Idaho, Nevada, and Oregon meet. In this area, there’s at least one place that’s 44 miles from the nearest major highway… in the distance, you can find Idaho Highway 51, as well as two separate sections of US Highway 95.
Northwestern Arizona
When visiting the Grand Canyon, don’t overlook the chances for hiking and backpacking that aren’t advertised by the tourist agencies. There’s quite a distance from one rim to the other, and roads aren’t exactly plentiful (especially on the western side of the canyon.) There is at least one point in the eastern part of Grand Canyon-Parashant National Monument that is exactly 50 miles from both Interstate Highway 15 and Arizona Highways 66 and 389. Add to that the lack of highways on the western side of the canyon (you won’t reach any until you’re around the Nevada border), and the Grand Canyon starts looking more and more like a hiker’s paradise.
