North of the Colorado River
The principal entrance to the north section of the NCA is I-70 exit 2,
Rabbit Valley, where a good quality track heads south for 5 miles past one trailhead (McDonald Creek) and two red rock outcrops (the Castle Rocks) to a campground and viewpoint right on the rim of the Colorado River canyon, here around 300 feet deep; this is
Knowles Canyon Overlook, named after a long drainage on the far side of the river. There are two other primitive campgrounds along the road, while RVs have a designated area further northeast in the valley, close to the interstate, reached by another unpaved road, better maintained, which ends a few miles further beyond the Rabbit's Ear trailhead, start of a 5.6 mile path that loops around a block of elevated land, giving views of the Colorado and Grand Mesa. Further east, accessed from exits 11 and 15, are many more trails, mostly for mountain bikes - across
Mack Ridge, the northeast edge of which is straight and steep, while the opposite side slopes more gently and is split by a number of canyons.
South of the Colorado River
Black Ridge Canyons Wilderness makes up nearly all the land south of the Colorado, and this section of the NCA has road access in just three places. One track follows the southern edge to trailheads for
Knowles Canyon and
Jones Canyon, while in the northeast, the most used entrance is along Kingsview/Pollock Bench Road, which forks off the western route into Colorado National Monument. Again there are many intersecting trails here, open to hikers and horses, including a 7 mile route to the Rattlesnake Arches, along
Rattlesnake Canyon. This location may also be approached from the south via a much shorter hike (2 miles) though 4WD is required to reach the trailhead. This road also passes the trailhead for
Mee Canyon, which like Knowles and Jones contains alcoves, overhangs, pinnacles, arches and another formations, though not any major ancient ruins or rock art sites.
