Uinta Highline Trail Packing List 2026: Complete Utah Kit

Your Uinta Highline Trail packing list for 2026 must cover 5-8 self-supported days above 10,000 ft (3,050 m) with no resupply: a 55-65 L pack, a 20 F (-7 C) sleeping bag, a free-standing or fully enclosed shelter, rain shell, a bear canister or hang kit, and 5+ days of food. Afternoon lightning and mosquitoes drive most of the choices.

What makes the Uinta Highline Trail a unique packing challenge?

The Uinta Highline Trail is 104 miles (167 km) with about 16,000 ft (4,900 m) of ascent and no resupply points along the route. You carry everything for the entire trip from the start, which is why food weight and pack volume dominate planning. Sustained altitude, daily thunderstorms and dense mosquitoes in July further shape the list. Cross-reference the stage distances on the Uinta Highline Trail guide to size your food carry precisely.

Backpack: how much volume do you need?

For a 5-8 day no-resupply trip with a bear canister, target 55-65 litres. The Osprey Atmos AG 65 carries heavy first-day food loads comfortably thanks to its Anti-Gravity suspension. Weight-counters favour the Zpacks Arc Haul Ultra 60L at around 600 g, while the Deuter Aircontact Lite 45+10 offers an expandable middle ground for those starting lighter. Whichever you choose, fit the hipbelt to carry the 12-15 kg starting load on your hips, not your shoulders.

Shelter, sleep and insulation

Pack a shelter that fully zips closed - mosquitoes in July are relentless, so a tarp alone is a poor choice here. A double-wall or fully-meshed single-wall tent under 1.2 kg is ideal. For sleep, carry a sleeping bag or quilt rated to 20 F (-7 C), since lows reach freezing even in August and 20 F (-7 C) in September. Add an insulated pad with an R-value of at least 4.0 for the cold alpine ground, and a down jacket for camp and pass crossings.

Clothing and rain protection

Layer for a 40-degree daily temperature swing. The essentials:

• Synthetic or merino base layers (sun protection at altitude is critical)
• A fully waterproof rain shell and rain pants - storms are daily, not occasional
• Insulated down or synthetic jacket
• Warm hat, gloves and a sun hat
• A head net - non-negotiable in July
• Trail runners or light boots, plus camp socks

Food, water and the bear question

Plan 2,800-3,500 kcal per day, which works out to 700-900 g of food daily, or 4-6 kg for the trip. Water is abundant from lakes and snowmelt streams, so a 1-2 L capacity plus a filter is enough; you rarely carry more than a litre. Black bears live in the Uintas, so store food in a bear canister or use a proper hang at least 200 ft (60 m) from camp. The Ashley National Forest does not currently mandate canisters, but they remove all doubt and double as a camp seat.

Navigation, safety and the ten essentials

Cell coverage is effectively zero across the High Uintas. Carry a GPS app with the route downloaded offline, a paper map and compass as backup, and a satellite messenger for emergencies. Lightning is the leading killer in alpine Utah, so a watch alarm to enforce pre-noon pass crossings is a genuine safety item. Round out the kit with a first-aid kit, a repair kit, sun protection (SPF 50, UV-blocking sunglasses for snowfields) and a headlamp.

Before you leave

Check the Ashley National Forest for current fire restrictions and trail notices, and the National Weather Service Salt Lake City mountain forecast for the storm pattern across your trip dates. Time your departure with the best time to hike the Uinta Highline Trail guide, and weigh the physical demands using our Uinta Highline difficulty guide. Build your kit list and day-by-day food plan in HikeLoad's gear and food tools.

Cooking system and stove

An upright canister stove is the simplest choice for the Uintas, but altitude and cold reduce canister performance, so bring more fuel than a sea-level trip would need - budget about 15-20 g of isobutane per person per day for boiling water. Many thru-hikers run a minimalist setup: a 0.75-1 L titanium pot, a single canister stove and a long-handled spoon, eating freeze-dried or cold-soaked meals to save fuel and time. Check current fire restrictions before relying on any open flame; in dry late-summer the Ashley National Forest sometimes bans campfires entirely. A pack with external mesh and side pockets, such as the Hyperlite 3400 Windrider, keeps the canister and pot accessible without digging through the main compartment.

Sample 7-day load breakdown

A realistic target for the full traverse is a base weight (everything except food, water and fuel) of 6-8 kg, plus about 5 kg of food and 0.5 kg of fuel on day one. That puts a typical starting load at 12-14 kg, dropping roughly 0.8 kg per day as you eat. Ultralight hikers using a frameless or minimal-frame pack like the Zpacks Arc Haul Ultra 60L push base weight under 6 kg, while those prioritising comfort with the Osprey Aether 65 accept a heavier carry for better load transfer. Weigh every item before you leave - the difference between a 14 kg and an 11 kg starting load is felt acutely on the climbs to 12,700 ft (3,870 m). Test your fully loaded pack on a steep local hill beforehand; if it carries comfortably for a few hours, it will serve on the Uinta Highline Trail and on bigger objectives like the Continental Divide Trail.

Frequently Asked Questions

How big a backpack do you need for the Uinta Highline Trail?

A 55-65 L pack is right for the 5-8 day, no-resupply trip, large enough for a bear canister and 5+ days of food. Ultralight hikers can manage 50-55 L, but the full food carry on day one is the limiting factor, not gear bulk.

Do you need a bear canister on the Uinta Highline Trail?

A bear canister is not currently required by the Ashley National Forest in 2026, but black bears are present, so secure food storage is essential. A canister is the most reliable option; otherwise use a proper bear hang at least 200 ft (60 m) from camp and 10 ft (3 m) off the ground.

How much food should you carry for the Uinta Highline Trail?

Plan 2,800-3,500 kcal and 700-900 g of food per day. For a typical 7-day trip that is roughly 5 kg of food carried from the start, since there are no resupply points anywhere along the 104-mile (167 km) route.

What temperature sleeping bag do you need?

A bag or quilt rated to 20 F (-7 C) covers the full mid-July to mid-September season. Summer lows at 10,500 ft (3,200 m) hover near freezing, and early-September nights can drop to 20 F (-7 C), so a 30 F (-1 C) bag is too marginal for late-season trips.

Do you need a water filter on the Uinta Highline Trail?

Yes. Water is abundant from lakes and snowmelt streams, but it should be filtered or treated against giardia. Because sources are so frequent, you rarely need to carry more than 1 litre at a time, which keeps pack weight down.
