The main (south) entrance to
Black Canyon of the Gunnison National Park is along US 50 then Hwy 347, 13 miles from Montrose. The much less visited North Rim is reached by several miles of unpaved roads, starting from Crawford along Hwy 92.
The distance between the two entrances is 86 miles in the east, via Curecanti National Recreation Area, or 78 miles in the west, via Delta.
