A canyon so deep and narrow the bottom barely sees the sun.

Some canyons are wide and sunny; the Black Canyon of the Gunnison is the opposite — a sheer, dizzying slot so narrow and so deep that parts of the floor get only about half an hour of direct sunlight a day. That permanent shadow is where the name comes from. The Gunnison River carved it through some of the hardest, oldest rock in North America, dropping at a ferocious rate, and the result is a chasm of dark, near-vertical walls plunging more than 2,000 feet — including the Painted Wall, Colorado's tallest cliff at 2,250 feet, streaked with pale veins of pegmatite.
You experience it mostly from the rim. The South Rim Road strings together a series of overlooks where you step to a railing and the earth simply drops away — Gunnison Point, Chasm View, the Painted Wall, Dragon Point — each a gut-check view into the gorge. The inner canyon is true wilderness, reached only by steep, unmaintained routes for experienced, permitted hikers; to stand by the river without that effort, the steep East Portal Road switchbacks down to the water.
The South Rim near Montrose is the main, accessible side, open year-round to the visitor center (the rim road beyond closes in winter); the North Rim is a remote, partly-gravel drive around with no bridge connecting them. It's a certified Dark Sky Park with superb stargazing, and it sits right on the route between Montrose and the San Juan Mountains. (Note: a 2025 fire burned parts of the South Rim — check current trail and campground conditions.)
The marquee stop — Colorado's tallest cliff at 2,250 feet (taller than the Empire State Building), the near-black rock streaked with pale pink pegmatite dikes.
Insider tipLight is best mid-to-late morning, when the dikes pop against the dark wall. It's a short walk from the pull-off.
Plan a trip to this spot →The closest overlook to the South Rim Visitor Center — the quickest 'first wow,' with a sheer plunge straight to the river.
Insider tipPair it with the visitor center exhibits before driving the rest of the rim road. Good for those short on time or mobility.
Plan a trip to this spot →The park's signature narrow-and-deep sensation, where the canyon pinches dramatically and the river roars far below.
Insider tipListen and look across for climbers on the walls. Not for anyone uneasy with sheer exposure.
Plan a trip to this spot →One of the best frontal views of the Painted Wall and a classic composition of the canyon's curve.
Insider tipA strong sunset spot, when the low sun rakes across the canyon walls.
Plan a trip to this spot →A short interpretive trail to the highest, westernmost viewpoint, with panoramas of the canyon, the West Elk Mountains, and the San Juans.
Insider tipAbout 1.5 miles round trip — the best end-of-drive payoff. Bring water; it's exposed at 8,000-plus feet.
Plan a trip to this spot →A steep paved descent (a 16% grade) dropping to the Gunnison River — the only drive-to access to the canyon floor.
Insider tipVehicles and trailers over 22 feet are prohibited; use low gear both ways. The road closes in winter.
Plan a trip to this spot →High and dry. The weather station down in Montrose (~5,800 ft) gives the regional picture — warm summers, cold snowy winters, and a late-summer monsoon — but the South Rim sits at about 8,000 feet and runs roughly 8–12°F cooler with more snow, which is why the rim road beyond the visitor center closes in winter. The canyon floor, by contrast, tracks closer to the warmer Montrose readings.
The South Rim is the main, accessible side; the North Rim is a remote drive around with no bridge between them.
About 15 minutes from Montrose — the visitor center and the 7-mile string of overlooks. The side virtually all visitors use.
A remote, partly-gravel drive near Crawford, with quieter overlooks and first-come camping. No road connects it to the South Rim — it's a 2–3-hour drive around.
No lodging in the park — campgrounds on each rim, plus gateway towns. (The South Rim campground was reduced after the 2025 fire.)
The main in-park campground near the visitor center, reservable year-round on Recreation.gov — reduced to fewer, non-electric sites after the 2025 South Rim Fire.
Booking tipVerify current site availability when you book; the fire changed the campground.
The remote North Rim campground is first-come; East Portal sits at river level (reached by the steep East Portal Road, with size limits and a winter closure).
Booking tipThese are quieter, more primitive options for those willing to work for them.
Montrose (the largest, ~15 minutes from the South Rim) plus Crawford (nearest the North Rim) and Gunnison (~1 hour east) cover hotels and supplies.
Booking tipMontrose is the practical base for a South Rim visit.
What does it cost?
$30 per vehicle (good for 7 days), $25 motorcycle, $15 per person; a Black Canyon annual pass is $55 and the $80 America the Beautiful pass works. The entrance is cashless, and there's no timed entry.
When should I go, and does the road close in winter?
May through October is peak, with the full South Rim Road open. In winter the rim road closes beyond the visitor center (the area stays open for snowshoeing), and the North Rim and East Portal roads close entirely.
Can I hike to the bottom?
Only experienced hikers should. The inner canyon is wilderness with no maintained trails — the descent 'routes' are steep, unmarked, and strenuous and require a free wilderness permit. To reach the river by car instead, take the East Portal Road.
Why is it called the Black Canyon, and how deep is it?
It's so steep, narrow, and deep that parts of the floor get only about 33 minutes of direct sunlight a day, leaving the walls in near-constant shadow. It plunges over 2,000 feet, narrows to as little as 40 feet at the river, and holds the Painted Wall — Colorado's tallest cliff at 2,250 feet.
North Rim or South Rim?
The South Rim, off US-50 near Montrose, is the main, accessible, year-round side. The North Rim is remote, partly gravel, first-come, and winter-closed — a quieter experience for those willing to drive the long way around.
Is it good for stargazing?
Excellent — it's a certified International Dark Sky Park with superb year-round stargazing and ranger astronomy programs in season.
Pick your vehicle, line up the stops on the way in and out, and carry the whole route in your pocket.
