A narrow canyon with demanding access

Black Canyon of the Gunnison Wilderness protects a rim-to-rim stretch of canyon within Black Canyon of the Gunnison National Park in Colorado. Designated in 1976, it covers roughly 15,599 acres. The landscape centers on ancient Precambrian gneiss, resistant rock that the Gunnison River has cut into a deep, narrow gorge. Piñon and juniper forest surrounds the canyon, while the walls limit sunlight reaching the bottom. At The Narrows, the canyon measures about 1,100 feet across at the rim and as little as 40 feet at the bottom. This is not a destination where a short mileage figure means an easy outing. Reaching the river means descending steep, loose terrain and saving enough strength for the climb out. Angling, river-bottom camping and demanding climbing draw visitors into the wilderness, but the cliffs are not suitable for inexperienced climbers.

Unmarked routes and fire-affected terrain

Inner-canyon routes are not maintained or marked trails. They follow steep gullies and rock chutes, with loose dirt, loose rock and frequent scrambling. Although described as nontechnical, they are very strenuous, and finding the return line can be harder than finding the way down. Turn around regularly during the descent and study recognizable rocks, trees and other landmarks. First-time visitors should review route-specific information and speak with a ranger at the visitor center before committing. Effects of the 2025 South Rim Fire add important limits: the Tomichi Route is closed to all use until further notice, while Gunnison and Warner remain open under the reservation system. On Gunnison, burned-area hazards include unstable slopes, loose rocks, burned vegetation and potentially unstable trees. Mobile service is unavailable, and rescue can take many hours to more than a day. Carry enough equipment for an unplanned overnight and be prepared to turn back.

Heat, water and nights beside the river

Inner-canyon temperatures run 5–10°F warmer than the rim, and heat exhaustion is the most common injury on the descent routes. In summer, start as early as daylight permits. Plan access to four liters of water per person per day; the river at the canyon bottom is the only water source along the routes, so carry a filter or treatment method if replenishing there. Bring your own drinking water from October through May, when drinking-water service is unavailable. Most South Rim routes are snow-covered from November through April, and winter conditions can make travel difficult or impossible; traction devices are recommended. River-bottom camping is possible for up to three nights. Fires are prohibited except for camp stoves, and bear-proof canisters are strongly recommended. The Gunnison is swift, cold and deep, making swimming and wading inadvisable. Riverbank travel ends at cliffs; do not plan a through-hike or a descent on one route and ascent on another.

South Rim permits and trip planning

South Rim wilderness trips require a permit for the selected route. During the May 1–October 31 peak season, reservations and permits are available only through Recreation.gov. For 2026, reservations opened April 1 at 8 a.m. Mountain Time for May through July trips, and July 1 at 8 a.m. for August through October trips. From November 1 through April 30, permits are first-come, first-served outside the Black Canyon South Rim Visitor Center, without reservations; the same daily quotas apply. The open Gunnison Route has a quota of 15 hikers per day or night, and Warner has 23. Maximum group size is four, with a three-night maximum stay. Once a permit is printed, modifications and cancellations are not allowed. Display the permit number on the vehicle dashboard. North Rim permits are not available online; confirm arrangements with the park. Pets are not allowed on wilderness routes.

Hazards & regulations

  • Inner canyon routes are unmarked, very steep scrambles through loose dirt, gullies and rock chutes—not maintained trails. Navigation can be especially confusing uphill; look back frequently during descent and memorize landmarks.
  • The Gunnison Route has hazardous burned-area conditions from the 2025 South Rim Fire: steep unstable slopes, loose rocks, burned vegetation and potentially unstable trees.
  • Heat exhaustion is the most common injury on the routes. The inner canyon is 5–10°F warmer than the rim, with water access only at the river.
  • The river is swift, cold and deep; swimming and wading are not recommended. Riverside travel eventually cliffs out, making route-to-route traverses unrealistic without intimate canyon knowledge and entering the river.
  • Mobile service is unavailable. Rescue can take many hours to more than a day to mobilize. Carry supplies for an unplanned overnight and turn back before exceeding your capabilities.
  • Most South Rim routes are snow-covered November through April. Winter conditions may make travel impossible; traction devices do not remove the underlying steep-terrain hazards.

Black Canyon of the Gunnison Wilderness FAQ

How do you reach the two rims?
Reach the South Rim from Montrose via U.S. Highway 50 and CO Highway 347. Reach the North Rim from Crawford via CO Highway 92 and unpaved North Rim Road. There is no bridge between rims; allow two to three hours to drive between them. There is no public transportation within the park.
Are these suitable beginner hikes?
No. Inner canyon routes are primitive, very strenuous scrambles without maintained or marked trails. Review route-specific information and speak with a ranger, especially before a first descent. The canyon's demanding climbing routes are also unsuitable for beginners.
Can you descend one route and climb out another?
Do not plan a route-to-route traverse. Riverside routes eventually cliff out, and river access typically extends no more than a mile. Traversing requires intimate canyon knowledge and entering the swift, cold river. Return by the route used to descend.
Can you camp beside the river or bring a dog?
Permit holders may camp at their route's base for up to 3 nights. Fires are prohibited except for camp stoves. Bear-proof canisters are highly recommended. Pets are not allowed on wilderness routes.
What should permit holders do before leaving?
Print the permit through Recreation.gov no later than the entry date and display its number on the vehicle dashboard. Printing issues the permit, after which modifications and cancellations are not allowed. For a day trip, select 0 nights even if the availability display shows departure the following day.
What defines this wilderness?
The wilderness protects 14 miles of the Black Canyon from rim to rim. The Gunnison River cuts through resistant Precambrian gneiss beneath steep, shaded walls, with piñon and juniper forest around the canyon. At The Narrows, the canyon bottom is as little as 40 feet wide.
