RMNP Wilderness Gear Checklist

What shapes your gear on Rocky Mountain National Park

Designated sites only

There is no dispersed camping. The park assigns named sites, and the permit you reserve lists the camp areas and dates.

The paper permit

Permits and car dash tags are collected in person at a Wilderness Office, open 7 a.m. to 3:30 p.m., and the permit is a printed copy with no electronic option. Summer reservations opened March 1 at 8 a.m. Mountain time. The permit travels on the outside of your pack and then on your tent.

Permit fee

The park's rules sheet lists a $36 administrative fee per permit from May through October, not refundable and separate from the entrance fee. One blogger's 2026 note agrees and adds that it covers the whole trip, whatever the number of nights or people.

Storms

The park warns of lightning that is common daily, wind gusts and extreme weather in summer. A hiker who booked one night at Arch Rock in late summer wrote that afternoon storms are common in summer and watched the forecast for a week.

Wind above treeline

On an August 2009 trip above Upper Granite Falls camp, about 55 degrees with a 20 mph west wind felt awfully chilly, and one party turned back on Bighorn Flats because the wind grew worse on the tundra.

Cold nights

At a 9,800 foot camp in August, the same party kept adding clothing until they had nothing left to add, then went to bed. A September party in the Odessa Gorge met snowfields frozen hard at dawn.

Marmots and bears

A blogger who camps often in the park says marmots can chew through packs and tents to reach food, and she puts the park's black bear count at around 30. She notes there are no grizzly bears in the park.

What hikers carry on Rocky Mountain National Park

• A canister sized for the whole trip, opened at home first

  A 2009 party found a rented canister left no space for their stove and part of their food. A 2022 hiker practiced opening hers beforehand, then still needed a few tries at 8,240 feet. Another blogger says rangers ask how it works and once felt her pack for it.

• Waterproof pack covers

  The Arch Rock hiker bought them after seeing downpours in the forecast. Rain hit 20 minutes up the trail, and she wrote that the covers kept everything inside dry. With no fire allowed, wet clothes cannot be dried at camp.

• A filter with a backup

  Camps sit by creeks and lakes, and parties filtered about 3 gallons at once to fill every bottle. One blogger carries chemical tablets as a backup and, when lows are in the 40s or below, sleeps with her filter so it cannot freeze and fail.

• Warm layers and a windproof shell

  Wind at treeline turned a 55 degree morning into a retreat for one party, and their camp at 9,800 feet needed every layer by night.

• Bug protection

  Mosquitoes arrived at dusk at Arch Rock and were crazy at Glacier Gorge, where a blogger and her partner bundled up and retreated to the tent early.

• Microspikes and an ice axe late in the season

  A September party reached the Continental Divide over snowfields frozen almost solid, and was glad of microspikes and ice axes. The park also lists spikes, crampons or snowshoes as possible needs.

• An offline map and a shared plan

  Cell service is spotty at best. The Arch Rock hiker saved a map offline and told several people her route and return time.

  From Bassmaster

• Waste bags and your own toilet paper

  Some sites have a privy, some require carrying waste out, and a privy supplies no paper. A blogger says to check each site's detail page.
