Black Canyon South Rim Gear Checklist

What shapes your gear on Black Canyon South Rim routes

Route sizes on the park page

The park lists the Gunnison Route at 1.5 miles one way with an 1,800 foot drop, the Warner Route at 2.75 miles with a 2,722 foot drop, and the Tomichi Route at 1 mile with a 1,960 foot drop. Recreation.gov adds the nature trail to the Warner figure and lists 3.5 miles one way. A 2019 backpacker describes the Warner descent as 1.6 miles after a 0.8 mile nature trail.

How long the Warner Route takes

The park gives 2 to 2.5 hours down and 4 hours up. Recreation.gov gives 2 to 3 hours down and 4 to 6 up. A 2019 overnight pair took about 4 hours down and a little over 2.5 hours up. A May 2026 day hiker took about 2.5 hours down and found the climb out slow, with many breaks in limited shade.

Where the river leaves you

The park lists river access at 0.75 mile from the Gunnison Route bottom and 1 mile from the Warner Route bottom, at low water. Recreation.gov says every route eventually cliffs out along the river, and that floods can come between mid-May and mid-July. Cold, swift water makes wading and swimming dangerous.

Poison ivy

The park says you will struggle to dodge poison ivy, which can grow 5 feet tall beside the river. Recreation.gov calls it prevalent on the lower routes and all along the Gunnison River.

Fees and stay length

Recreation.gov lists a $6 reservation fee, $4 per person, and the park's $30 vehicle entrance fee. One permit covers one route and up to 3 nights at the river camps, and campsites are to be vacated by 11 am on hike-out day. A 2025 Gunnison Route guide says only 1 night is allowed.

Status when we read the park pages

On 2026-10-22 the park page said the Warner and Gunnison routes were open by reserved permit, the Tomichi Route was closed after the 2025 South Rim Fire, and Gunnison Route hikers faced burned-area hazards such as unstable slopes and trees. Check the park alerts before choosing a route.

What hikers carry on Black Canyon South Rim routes

• Long pants for the poison ivy

  A 2019 backpacker says poison ivy runs rampant at the bottom, handled long pants carefully, and called them a must. A 2025 Gunnison Route guide says long pants shield your legs from ivy and from ticks. A May 2026 Warner day hiker walked the river bank carefully to avoid the abundant ivy.

• A water filter for the river

  Water exists only at the Gunnison River, so the 2019 Warner pair listed a filter for camp. The park says to have 4 liters a person a day and notes that a filter can lighten the load. A fast Gunnison Route party that started at sunrise drank about 2 liters each.

  The sources print different totals. The park says 4 liters, the fast party used about half of that.

• A bear canister, borrowed if needed

  The 2019 pair carried one and says the park requires it and lends them at the visitor center. The park text we read says highly recommend, not require.

  This is a conflict between a hiker's account and the park pages. See the agency section.

• Gloves for the chain

  The 2025 Gunnison Route guide says gloves protect hands on the chains and if you fall. The park describes one 80 foot chain a third of the way down, while the guide counts two chains back to back of about the same length.

• Shoes with real traction

  The Gunnison Route guide says to wear hiking shoes or boots with good traction and nothing else. The 2019 pair slid on loose dirt, dug heels into scree and climbed down boulders 4 to 5 feet tall with heavy packs.

• A rain jacket for afternoon storms

  The 2019 pair had a flash flood scare when storm clouds rolled over the narrow canyon and says afternoon thunderstorms are common. The park lists layers and rain gear in its short list.

• Map, compass and photos of the descent

  The park says GPS devices often do not work in the canyon. The Gunnison Route guide used a GPS and still lost the trail briefly, then suggests photographing the descent to compare on the way up.

  The park and the guide disagree about GPS. Carry a map and compass either way.

• Shirt and hat to soak in the river before the climb

  A May 2026 Warner day hiker wet shirts and hats at the river to stay cooler on the climb out. The cooling did not last long, and the way up was slow in limited shade.
