Yellowstone Packing List

Updated September 2026 · Vacation Checklists

A yellowstone packing list is really four small lists stacked on top of each other: clothes for a day that starts below freezing and ends in the eighties, bear spray you cannot fly in with and have to source once you arrive, footwear that works on wet boardwalks and rough trails in the same afternoon, and a car kit for a park where the drives are long, the gas stations are few, and your phone stops working somewhere past the entrance station.

Get the base list started with our free packing list generator, then work through the park specific sections below.

Updated September 2026. Yellowstone road openings and closures, campground and dining availability, thermal area closures, and bear activity warnings change constantly and by season. Most park roads close to regular vehicles for the winter and reopen in spring on a staged schedule, so check the park's current conditions and road status pages on nps.gov within a few days of your trip, and again the morning you drive in.

What This Page Owns

Our national park packing list covers the trip level mechanics that apply to any park: passes, timed entry and permit systems, and how to book what needs booking. Start there for the paperwork.

Our road trip packing list owns the car itself, including the front seat kit, the trunk, and the vehicle emergency kit that should live in your car permanently.

Our camping checklist owns tents, sleep systems, and campsite cooking, which is what you need if you are staying inside the park at a campground rather than in a hotel in a gateway town.

This page is one park in depth. Yellowstone is big, high, cold at dawn, and short on services, and those four facts drive almost everything you should pack.

The Temperature Swing Is the Whole Problem

Most of Yellowstone sits between roughly 6,000 and 8,500 feet. Old Faithful is around 7,350 feet. Yellowstone Lake is above 7,700 feet. Dunraven Pass tops 8,800 feet. At that elevation the air holds very little heat overnight, so the sun does all the work during the day and the temperature falls off a cliff at sunset.

The result is a swing of 30 to 40 degrees Fahrenheit inside a single summer day, and frost on the car in June, July, or August is unremarkable.

Shoulder season makes that swing wider rather than narrower, and snow can fall in any month. September and October trips regularly include one genuine snow day.

Bear Spray: Buy It or Rent It in the Region

You cannot fly with bear spray. It is prohibited in carry on baggage and it is prohibited in checked baggage, because it is a large pressurized canister of capsaicin treated as a hazardous material. Packing it in a hard case, in a duffel, or in a suitcase does not change that. Security will find it and you will lose it.

Everyone flying into Bozeman, Jackson, Cody, Idaho Falls, or Salt Lake City gets it the same two ways:

1. Buy a canister once you land. Outdoor shops and general stores in West Yellowstone, Gardiner, Cooke City, Cody, Jackson, and Bozeman stock it through the season, and so do several stores inside the park. Buy it on arrival day rather than on the morning of a hike, since shops do sell out in peak weeks.
2. Rent one. Seasonal rental programs have operated in the park and in the gateway towns in recent years, including a well known one at Canyon Village, and renting solves the disposal problem because you simply hand it back. Availability and locations change year to year, so confirm before you count on it.

Plan how it leaves. You cannot fly home with the canister either. Return the rental, pass an unused canister to another visitor, or use a drop off or donation bin. Several regional airports and visitor centers in the Yellowstone area have offered these bins, and they are the right answer rather than a hotel dumpster. Never leave a canister in a hot car, where heat can cause it to vent.

Using It Properly

• Carry it on a hip or chest holster where your hand reaches it in one motion. In the trunk or the bottom of a daypack it does nothing.
• Learn the safety clip and the spray pattern before you are on a trail. Inert practice canisters exist.
• Check the expiration date when you buy or rent.
• Spray is a last resort. Making noise, hiking in a group, keeping food secured, and giving animals room prevent almost every encounter.
• If you are driving in with your own canister, that is fine domestically, but keep it out of direct sun and out of a closed hot vehicle.

Wildlife Distances Are Rules, Not Suggestions

Yellowstone sets specific minimum distances, and they are enforceable. Stay at least 100 yards from bears and wolves, and at least 25 yards from all other wildlife, including bison, elk, moose, and coyotes. That is roughly the length of a football field for predators and a couple of car lengths for everything else.

Bison injure more people in Yellowstone than bears do, usually because someone walked closer for a photo. They are fast, they are unpredictable, and a bull can weigh close to a ton. The behavioral test is simple: if an animal notices you, changes what it is doing, or moves away, you are already too close.

Practical version:

• Stay in your car during a wildlife jam unless there is a safe pullout and room to stand well back.
• Never get between an adult and its young, or between an animal and its escape route.
• Never feed anything, including birds and ground squirrels at picnic areas.
• Keep food, coolers, and scented items stored per the rules at your campground or picnic area, and never leave a cooler unattended on a table.
• Binoculars are the answer to nearly every urge to get closer.

Boardwalks and Geyser Basins: The Footwear Nobody Plans For

Geyser basins are the reason most people come, and they are their own small environment.

The ground in a thermal area can be a thin crust over boiling water, which is why the boardwalks and marked trails are not optional and why straying off them has killed people. Beyond that hard rule, the basins ask something specific of your shoes and your gear:

• Boardwalks get slick. Overnight frost, thermal runoff, and afternoon rain all leave planks wet, and morning frost on a raised boardwalk with no railing is genuinely slippery. Closed toe shoes with a grippy sole beat sandals and beat smooth soled sneakers.
• You will walk further than you expect. Some basin loops run a couple of miles, on hard surfaces, in full sun.
• Steam condenses on everything. Glasses fog, camera lenses bead up, and phone screens go unresponsive. Carry a cloth.
• The air is acidic and sulfurous. Steam can tarnish silver jewelry and leave a film on gear. People with asthma or breathing sensitivities sometimes find the hydrogen sulfide in the basins uncomfortable, so keep an inhaler accessible if you carry one.
• Pets are not allowed on boardwalks, trails, or in the backcountry, and a hot car is not a plan.

Same trip, different surface: the trails away from the basins are dusty, rocky, and often muddy in spring, which is where hiking shoes earn their place. Our hiking packing list covers the day hike kit and the blister routine in detail, and if you are deciding between a boot and a low shoe for the trail pair, our comparison of hiking boots vs trail runners works through it by pack weight and terrain.

Distances, Gas, and No Cell Service

Yellowstone covers more than two million acres and is larger than Rhode Island and Delaware combined. The Grand Loop Road is a figure eight roughly 142 miles around, the maximum speed limit in the park is 45 miles per hour, and the real average is far lower once you add construction, animal jams, and full parking lots.

Three rules that prevent most Yellowstone driving problems:

1. Fill the tank in the gateway town. In park fuel exists at a handful of developed areas, but hours are limited and seasonal, and the distances between them are long.
2. Download offline maps for the whole region before you arrive. Cell service in Yellowstone is limited to a few developed areas, congested where it exists, and absent across most of the park and nearly all of the backcountry. Assume you cannot look anything up, call anyone, or load a map tile.
3. Plan one region per day. Geyser basins one day, canyon and Hayden Valley another, Lamar and Mammoth another. People who try to see the whole loop in a day see a windshield.

Add a downloaded playlist or podcast before you lose signal, tell someone outside the park your plan for each day, and keep a paper map in the glove box.

Bring a Cooler, Because Dining Is Scarce

In park dining is limited, concentrated in a few developed areas, often requires reservations for the sit down rooms, closes earlier than you expect, and can mean a long wait at exactly the hour you are hungry. Between those areas there is nothing for an hour or more of driving.

A cooler fixes the whole problem, and the park has an enormous number of picnic areas with tables.

Pack for it:

• Hard sided cooler with block ice, which lasts far longer than cubes
• Sandwich makings, fruit, cheese, and snacks for two meals a day
• Breakfast you can eat in the car at six in the morning, because that is when the animals are out
• A thermos of coffee filled the night before
• Reusable plates, cups, cutlery, and a cutting board
• Wet wipes, paper towels, and a trash bag since not every picnic area has running water
• Food storage discipline, meaning nothing is left on a table unattended and everything goes back in the vehicle between meals

Restock in the gateway towns, which have real grocery stores. Inside the park the general stores are smaller and the selection is thinner.

Altitude and Sun at 8,000 Feet

Yellowstone is high enough to matter for a visitor who flew in from sea level yesterday. Most people notice only that they are winded on a short climb and that they sleep poorly the first night, both of which are common and usually pass.

Handle it conservatively: make the first day an easy one, drink more water than feels necessary, go light on alcohol the first night, and treat a bad headache with nausea or breathlessness at rest as a reason to descend and get medical advice rather than push through. Anyone pregnant or managing a heart or lung condition should ask their own doctor before the trip.

Sun is the other altitude effect, and it is stronger than people expect. Ultraviolet exposure rises with elevation, the geyser basins have no shade whatsoever, and a breezy 65 degree morning burns skin as efficiently as a hot beach.

Frequently Asked Questions

What should I wear in Yellowstone in summer?

Layers. A wicking base layer, a fleece, a light puffy, and a waterproof shell, plus a warm hat and gloves that stay in the daypack all day. A single summer day commonly runs from near freezing at sunrise to the eighties in the afternoon, and no one outfit covers both ends.

Can I bring bear spray on a plane to Yellowstone?

No. It is banned in carry on and checked baggage alike, and it will be confiscated. Buy a canister in a gateway town or inside the park once you arrive, or rent one where a rental program is operating, and plan to return, donate, or properly dispose of it before you fly home.

What shoes do I need for Yellowstone?

Two pairs. Closed toe shoes with grippy soles for the boardwalks, which get slick with frost, rain, and thermal runoff, and broken in hiking shoes or light boots for the trails, which are rocky and dusty in summer and muddy in spring.

How far apart is everything in Yellowstone?

Much farther than the map suggests. The Grand Loop Road is about 142 miles, the speed limit tops out at 45 miles per hour, and wildlife jams and construction slow that further. Plan one region per day and expect an hour or two of driving between major sights.

Does my phone work in Yellowstone?

Barely. There is limited service in a few developed areas and effectively none across the rest of the park. Download offline maps for the whole region before you arrive, carry a paper map, and do not plan on making a call or looking anything up from the road.

Do I need a cooler for Yellowstone?

Yes, for most trips. In park dining is limited, concentrated, often busy, and closes early, while picnic areas are everywhere. A cooler with two meals a day in it saves hours and lets you eat where you are rather than driving back to a lodge.

How close can I get to a bison in Yellowstone?

No closer than 25 yards, which is the park minimum for all wildlife other than bears and wolves. Those two require at least 100 yards. Bison injure more visitors than any other animal here, and almost always because someone approached for a photo.

Is Yellowstone open in winter?

Partly. Most park roads close to regular vehicles for the winter and reopen on a staged schedule in spring, while the road between the North Entrance and Cooke City has historically stayed open year round. Winter access to the interior is by guided snowcoach or snowmobile. Confirm current dates on the park's road status page, since they shift with conditions every year.

The Short Version

Pack for two seasons in the same day: base layer, fleece, puffy, and shell, with a hat and gloves you carry in July. Grippy closed toe shoes for boardwalks and real hiking shoes for trails. Binoculars, sunscreen, and a hat for basins with no shade.

Get bear spray after you arrive, wear it where you can reach it, and know how you are handing it back. Fill the tank before the entrance, download offline maps while you still have signal, plan one region per day, and load a cooler so that dinner is not a two hour problem.
