The Gunnison Route takes hikers from the south rim of the Black Canyon to the Gunnison River. It’s the most popular inner canyon experience on the south rim, but don’t let that fool you. This is a hard, strenuous hike where you will descend (and later hike back up) a massive amount of elevation in a short period of time.

On this hike, expect to get dirty. The hike down to the river is an almost constant battle not to wipe out or fall on your butt, as you hike down trails of gravel, loose rock, and scree fields. The way back up can be hot and exhausting. Your thighs are already fatigued from the journey to the river and now they must carry you back up to the rim.

It might not sound like it, but this hike is tons of fun. We laughed and joked on the way down, as we slipped and slid on the loose trail. Standing next to the Gunnison River, gazing up at the immense granite walls, was an unforgettable experience. It’s not so much fun on the way back up, but if you just keep putting one foot in front of the other, eventually you’ll be proudly standing on top of the south rim once again.

If hiking the Gunnison Route sounds like something you would like to do, get all of the details on how to have a successful hike in this post.

Facts About the Hike

Distance: 2.7 miles
Difficulty: Hard, strenuous
Elevation Gain: 1,772 feet
Elevation at the South Rim: 8,103 feet
Elevation at the Gunnison River: 6,344 feet
Length of Time: The average time to do this hike, according to the National Park Service, is 4 to 6 hours. However, if you move fast, you can do it in less time. We did it in 3 hours and 15 minutes, which includes 35 minutes spent down by the river.

Permit for the Gunnison Route

You MUST have a Wilderness Permit to do this hike.

Only 15 people per day are permitted to hike the Gunnison Route, for safety reasons and to reduce the amount of foot traffic on the trail.

The permit is free.

Permits are given out on a first-come first-served basis. The permits are given out 1.5 hours before closing time of the visitor center the day before your hike.

When we did this (July 2020), closing time of the visitor center was at 6 pm. After a 15-minute safety briefing at 4:30 pm, the permits were given out to the first 15 people that arrived to the meeting. On busy days, people start lining up as early as two and a half hours before closing time of the visitor center, which was 3:30 pm in July.

If you want to make sure that you get a permit, plan to arrive at least 30 minutes before the scheduled time, but you might need as much as a full hour on busy days (weekends and holidays).

To Summarize: If you plan to hike the Gunnison Route on Saturday, July 10, then you need to be at the south rim visitor center by 4 pm on July 9 (although 3:30 is even better). After attending the brief safety meeting, a park ranger will give you your permit for your group. The permit is free.

For more information about the permit, visit the national park service website. 

Important Things to Know About the Permit

When we did this, all members of our party did NOT have to be present in order to pick up the permit. We got a permit for four people even though only three of us attended the safety briefing.

If there are permits left over (not all 15 are taken the day before your hike), these last permits are given out at the visitor center on a first-come first-served basis at the visitor center the morning of your hike. But I would not count on this happening during the busy summer season or on weekends.

You must have your permit with you on the trail. A park ranger was checking for permits when we did this hike. If you do not have a permit, you will be fined.

After you finish your hike, let a park ranger know that you have completed the hike. If you finish after normal hours, place your permit in the self-registration box. This lets the national park service know that you have safely made it out of the canyon.

You are permitted to camp overnight, for one night, next to the Gunnison River. There are established campsites by the river and the national park service requests that you use one of these campsites.

Hiking the Gunnison Route: On the Trail

Getting to the Trailhead

The trail starts next to the South Rim Visitor Center. Park in the large parking lot here. There are toilets located next to the visitor center.

To hike the Gunnison Route, you will start the hike on the Oak Flat Trail, which starts behind the Visitor Center.

The Oak Flat Trail

You will walk down some steps to the Oak Flat Trail. Just a few minutes into the hike, the trail will fork. Stay to the right to continue on the Oak Flat Trail to the Gunnison Route.

Oak Flat Trail

You will hike the Oak Flat Trail for roughly a quarter of a mile, before reaching the trail for the Gunnison Route. The trail splits. There will be a sign stating that a Wilderness Permit is necessary to continue down this trail. This National Park Service sign marks the start of the Gunnison Route.

From this point, it is a steep, strenuous, difficult walk/scramble down to the Gunnison River.

On the Gunnison Route

At first, it doesn’t seem so bad. You are on a trail that switchbacks through the forest. Nothing too steep or strenuous, yet. There will be a few, brief scrambles over trees and their roots, but at first, the trail seems rather sedate.

Once you reach the chains, the trail gets steeper. There are two chains, back to back, about 80 feet in length, to help you get down the first steep descent of the hike. What left us puzzled is that this is not the steepest or most difficult section of the hike (that comes later, when there is no chain). But it’s a good warm up for what is coming.

Over the next mile, the trail rapidly loses elevation. At times you will be hiking down a steep dirt trail. And at other times, you will hike down large fields of rock and scree. During most of the descent, it’s a battle against gravity, not to slide and land on your butt. And there’s a very good chance that you’ll do just that. In our party of four, we had several good falls and wipe outs on the way down.

This is an unmarked trail. There are no trail signs to confirm you are moving in the right direction. You basically follow the faint, worn path of those who came before you. Most of the time, the trail is very obvious. But there are several spots where the trail is very faint or sketchy, and you will wonder if you are still on the trail. It helps to have a GPS for this hike (keep reading for recommendations).

Pro Travel Tip: Take photos of the trail with your camera or smartphone and use these for reference when hiking back up the trail.

Eventually, the Gunnison River will come into view. Once you see the river, you know you are getting close, and it’s a good gauge on how far you still have to go.

Almost to the River

As you approach the river, the temperature warms up, now that you are at a lower elevation. The air also feels a little more humid.

Along the final 200 meters of trail, you might see or come into contact with poison ivy. If you don’t know what poison ivy looks like, here’s a photo for you.

Once you make it the river, feel free to spend as much time as you like. With your permit you are allowed to spend the night here, if you desire.

There are shaded picnic areas, flat (yay!) trails along the river, and nice viewpoints of the Gunnison River. There is even a toilet here.

Once you have taken your photos, had your snack, and rested your legs, start back up the trail when you are ready.

Hiking Back Up to the South Rim

Essentially, you will retrace your steps back up the same trail to the visitor center. But if only it were that easy. It is a bit tricky to stay on the trail. We know, because we briefly stumbled off of the main trail.

On the way down, it helps to keep making mental notes of what the trail looks like. The Gunnison Route is an unmarked trail, so it’s easy to stumble off of it, either on the way down and/or the way back up. And since the route is limited to 15 people, you can’t count on following others on the trail.

It helps to have a GPS. We have a Garmin GPS, which tracks our route. We also wear Garmin Fenix watches. These watches, when in hiking mode, display the trail map. You can see the Gunnison Route on the Garmin Fenix watch. Several times it helped confirm that we were still on the trail.

The easiest place to lose the trail on the way back up is just before you reach the chains. You will be walking up a wide wash of rocks. To your left will be a large boulder. Stay to the right of this boulder, but head to the trail in the brush (where Tim is standing in the photo below). If you miss it, you will continue up the wash, which gets very steep, and you will lose the trail. So, keep an eye out for this boulder.

Once you make it to the chains, the rest of the route back to the visitor center is very straight forward. Somehow, the Oak Flat Trail seemed to have gotten longer, but maybe that’s just because we were hot and exhausted by this point.

Best Time to Hike the Gunnison Route

It is possible to hike the Gunnison Route all year.

The best time to hike the Gunnison Route is from May through October, when the trail is free from snow.

Snow begins to cover the trail in November. If you have plans to hike from November through April, you must be prepared and it is advised that you have crampons, an ice axe, snowshoes, and a rope.

Tips to Have the Best Experience

Start the hike early, ideally by 7 am, although earlier is even better. During the summer months the canyon can really heat up. An early start makes it more likely that you will be back on the south rim before temperatures really escalate.

Leave no trace. When you are in the park, practice the seven principles of Leave No Trace. This includes packing out what you bring into the park, be considerate of other hikers, stay on the trail, and do not remove anything from the park.

Do not expect your cell phone to work. During this entire hike we had no cellular service. Don’t depend on your phone to call for help, talk to friends, or send photos to friends and family.

Keep in mind the elevation. You are hiking at a relatively high altitude. If you are not acclimated to the elevation, it will make the hike back up to the rim more difficult.

What to Bring

Hiking shoes. Don’t do this hike in anything other than hiking shoes or hiking boots. You need good traction for this trail.

Water. The national park service recommends 4 liters of water per person during the summer months. If you are fit and fast, you can get by with less water. We did this hike very fast and started just after sunrise, when temperatures were cooler. We drank approximately 2 liters of water per person.

Sunblock. In the early morning hours, you will be out of the sun, since the sunlight does not enter the canyon fully until about 9 am in the summer. If you start late, take your time, or spend a lot of time down by the Gunnison River, you will be in the sun.

Long Pants. There is poison ivy near the river. Long pants will protect your legs from the poison ivy and the other vegetation you will come into contact with along the trail. They can also protect you from ticks.

GPS. This is not necessary but it makes it much easier to know that you are still on the trail. The GPS and trail maps on our Garmin watches was a great confirmation that we were still on the trail.

Gloves. These will help protect your hands on the chains. They can also protect your hands if you fall while on the trail.
