Colorado’s deepest canyon gets 30 minutes of sunlight and roars all day

It’s darker than you’d think

Black Canyon of the Gunnison National Park sits in western Colorado, just outside Montrose, and it looks nothing like the canyons you’ve seen before.

The Gunnison River spent roughly 2 million years cutting through rock that dates back about 1.7 billion years. Some sections of the canyon are so narrow and deep that sunlight reaches the bottom for only about 30 minutes a day.

The drop from rim to river hits 2,722 feet at the deepest point, and at the narrowest, only 40 feet separates the walls. The park earned national monument status in 1933 and became a full national park in 1999.

Colorado’s tallest cliff has billion-year-old magma streaks

The Painted Wall rises 2,250 feet from the river to the rim. Stack two Eiffel Towers on top of each other, and this cliff still wins.

Those colorful streaks running across the face come from ancient magma that pushed into cracks in the rock over a billion years ago, then cooled and hardened in place.

You can reach the overlook on an unpaved trail, about 200 yards from the parking area. Sunrise and sunset throw warm light across the wall, and photographers know it.

Twelve overlooks line a 7-mile rim drive

The South Rim Drive runs 7 miles and puts 12 overlooks in front of you, each one showing the canyon from a different angle.

Some sit just steps from your car. Others ask you to walk a bit. Gunnison Point, right by the visitor center, looks straight down into the canyon.

Pulpit Rock opens up a wide view across to the North Rim with the river curving far below. Chasm View drops your eyes to the river at one of the canyon’s tightest spots.

Give yourself two to three hours for the full drive with stops.

Hike the rim through oak, aspen, and Douglas fir

The Rim Rock Nature Trail follows the canyon edge for a mile, looking east down.

Warner Point Trail goes 1.5 miles round-trip and ends with views of the San Juan Mountains, the Uncompahgre Valley, and the canyon below.

The Oak Flat Loop runs about 2 miles round-trip and dips just below the rim through forests of oak, aspen, and Douglas fir.

That loop is the deepest you can go into the canyon without a wilderness permit. Cedar Point Nature Trail is a short walk with guideposts about the plants along the way.

The North Rim takes two hours to reach

No bridge connects the two rims, so driving from one side to the other takes about two hours. That keeps the North Rim far less crowded and a lot more rugged.

An unpaved road leads to five overlooks, including the Narrows, Balanced Rock, and Kneeling Camel. The Chasm View Nature Trail on this side is a short loop with a clear view of the Painted Wall.

The Civilian Conservation Corps built the North Rim road in the 1930s, and it now sits on the National Register of Historic Places.

No railings and 1,900 feet of air below

Exclamation Point on the North Rim is the viewpoint people talk about most.

You get there by hiking the North Vista Trail, about 3 miles round-trip, through juniper and sagebrush before the canyon rim opens up in front of you.

From the point, you look straight down a narrow corridor with the Gunnison River roaring nearly 1,900 feet below.

There are no railings here, so watch your footing near the edge. The sound of the water rises up and fills the space around you.

The river drops four times steeper than the Grand Canyon

The Gunnison River drops an average of 34 feet per mile through the canyon.

The Colorado River, by comparison, drops about 7.5 feet per mile through the Grand Canyon. Near Chasm View, the Gunnison plunges 240 feet in a single mile.

That kind of gradient gave the river enough force to cut through some of the hardest rock in North America.

You can hear it from many of the overlooks above, the sound bouncing off the canyon walls and carrying all the way to the rim.

Gold Medal trout at the bottom of a 7-mile descent

Colorado has over 9,000 miles of trout streams, and only 168 of them carry the Gold Medal label. The Gunnison River inside the park is one of them, also designated Wild Trout Water by the state.

Large rainbow and brown trout hold in the fast current here. East Portal Road drops from the South Rim to the river in about 7 miles on a steep, narrow path.

Only artificial flies and lures are allowed, and you have to release all rainbow trout.

Saturn’s rings show up through binoculars on clear nights

The park earned International Dark Sky Park status in 2015, and its distance from any major city keeps light pollution low.

On clear nights, you can see thousands of stars without any equipment. Bring binoculars, and you can pick out the rings of Saturn.

The park runs astronomy programs in summer and fall, with rangers and local astronomers setting up telescopes for visitors. Gunnison Point, the Painted Wall overlook and both campgrounds are popular spots for stargazing.

Peregrine falcons dive and bighorn sheep cling to the walls

The elevation change from rim to river creates a range of habitats packed into one park.

Over 125 bird species have been recorded here, including the peregrine falcon, the fastest bird in the world.

Mule deer show up along the rim regularly, and black bears move through the wooded areas near the trails.

Bighorn sheep sometimes appear on the steep canyon walls, where the terrain keeps predators away. River otters, elk, bobcats and mountain lions also live in the park.

A 2025 wildfire burned the campground but the overlooks reopened

In July 2025, a lightning strike started the South Rim Fire, which burned over 4,200 acres.

The fire destroyed most of the South Rim campground, several bathrooms and park buildings. Check the official NPS website for current conditions before you plan your trip.

By the end of August 2025, the South Rim road and overlooks reopened to visitors. Some trails and facilities are still affected, and the campground remains closed.

360,000 visitors a year means you’ll have the rim to yourself

Black Canyon of the Gunnison drew only about 360,000 visitors in 2023, making it one of the least-visited national parks in the country.

Rocky Mountain National Park, also in Colorado, pulls over 4 million a year. That gap means shorter lines, open parking lots and long stretches of canyon rim where you might not see another person.

Explore Black Canyon of the Gunnison in Colorado

You can start your visit at the South Rim Visitor Center, which stays open year-round.

The park sits about 15 miles east of Montrose off Highway 50 and Highway 347. The physical address is 9800 Highway 347, Montrose, Colorado.

The South Rim Road is usually open to vehicles from late April through mid-November.

In winter, you can only drive as far as the visitor center, but the rest of the road opens up for cross-country skiing and snowshoeing.

Entrance runs $30 per vehicle for seven days, and the park only accepts electronic payments. Annual national park passes work as well.
