Introduction

This list details the best backpacking trails in America. If one completes all 15 of these backcountry trails, he or she can rest assured they’ve backpacked America The Beautiful. A truly replete experience of the geographical bounty of the nation. There are other major trails to be sure, but this comprises the pantheon and provides a smattering of all major regions of the country. 

The list focuses on trails that can be done from 3 to 14 days. Three days is the minimum as it allows the one full day in the backcountry necessary to qualify as a backpacking trip. The two-week maximum was selected for those who want to use their precious two-weeks of vacation to tackle one of the premiere routes in America. Anything longer belongs in the conversation of thru-hikes. 

The order is arbitrary, but the metrics we’ve devised are paramount. True to our name, we have developed a number of data points by ratings that provide an easy, digestible way to analyze the trails according to length, elevation gain, difficulty, trail characteristics, seasonal access, available solitude, wildlife and insect pressure and other important features. While you will have to dive deeper in planning your specific trip, there is no better guide than Gear Analytica’s in helping you compare and contrast the best trails in America to help decide which to make your next journey.

• Wildlife Safety: 6/10 – black bears and mountain lions present, no grizzlies
• Permit Availability: 8/10 – Self-issued permits at trailheads, rarely reaches capacity
• Seasonal Access: 7/10 – Accessible year-round, but summer is hot and prone to monsoons and winter brings moderate chance of snow
• Resupply Options: 1/10 – no resupply options on trail
• Trailhead Access: 3/10 – Remote trailheads requiring driving on rough dirt roads, limited signage

Highlights: America’s first designated wilderness area, cliff dwellings, hot springs, river crossings, diverse ecosystems

Understanding the Backpacking Routes Metrics

This guide explains the metrics and rating systems used to evaluate backpacking trails in our story. These measurements help hikers compare routes and make informed decisions about which trails match their experience level and preferences.

Physical Metrics

Distance: Total length of the trail in miles. Our selected trails range from shorter routes (23-30 miles) that can be completed in 3-5 days to longer journeys (100-310 miles) requiring 1-2 weeks.

Duration: Suggested timeframe to complete the trail, typically ranging from 3-14 days. The minimum 3-day requirement ensures at least one full day in the backcountry to qualify as a backpacking trip. The extended 2-week trips are about the most time someone can usually take off work to get out on the trail.

Total Elevation Gain: The cumulative uphill climb measured in feet. This ranges from relatively modest (2,600 feet on the Lost Coast Trail) to extremely challenging (48,000 feet on the Long Trail).

Elevation Gain per Mile: Total elevation gain divided by distance, providing a standardized measure of uphill steepness. Lower values (100-150 feet/mile) indicate gentler terrain, while higher values (300+ feet/mile) suggest steeper, more demanding trails.

Absolute Grade: The average steepness of the trail, both up and down, expressed as a percentage. For reference:

• 2-5%: Easy rollers & river‑grade rail trails. You can chat while you walk and rarely need trekking‑pole support.
• 5-8%: Noticeable, steady ups and downs. Comparable to well‑built switchbacks in state parks.
• 8-11%: Extended, slope‑hugging climbs with few switchbacks and intermittent rock steps, changing elevation readily across ridges and valleys.
• 11+%: Sustained, staircase‑steep pitches with some scrambling. Descents can be slow and technical.

Trail Classification

Difficulty: Categorized as Easy, Moderate, Strenuous, or Expert:

• Easy: Gentle terrain, well maintained trails, suitable for beginners
• Moderate: Suitable for reasonably fit hikers with some backpacking experience
• Strenuous: Demanding trails requiring good physical condition and experience
• Expert: Technically challenging routes requiring advanced skills and excellent fitness

Terrain Profile: Describes the overall character of the landscape:

• Rolling: Consistent but manageable ups and downs
• Steep: Significant elevation changes and challenging ascents/descents
• Mixed: Varied terrain combining different features
• Mostly Flat: Minimal elevation change throughout

Trail Characteristics

Technical Features: Specific challenges such as stream crossings, exposed ridges, high altitude sections, or tidal considerations.

Trail Surface: Description of the physical trail conditions, from well-maintained dirt paths to rocky, rooty, or sandy surfaces.

Elevation Range: The lowest and highest points on the trail, measured in feet. This information helps hikers prepare for altitude considerations and temperature variations.

Ratings (Scale: 1-10)

Light Pack Weight: Rates how favorable the conditions are for pack weight (10 = most favorable/lighter packs, 1 = least favorable/heavier packs). Higher ratings indicate trails where you can carry less weight due to frequent resupply options, no bear canister requirements, or abundant water. Lower ratings indicate trails requiring heavy food carries, bear canisters, or substantial water carries between sources.

Weather Consistency: Rates predictability and severity of weather conditions (10 = most consistent/mild, 1 = unpredictable/extreme). Considers temperature swings, storm likelihood, and seasonal variations.

Water Availability: Rates how plentiful and accessible water sources are (10 = abundant, 1 = scarce). Critical for planning daily water carries.

Low Insect/Reptile Pressure: Rates the presence of troublesome wildlife (10 = few pests, 1 = significant pest pressure). Includes mosquitoes, ticks, flies, snakes, and other creatures that can impact comfort and safety.

Trail Solitude: Rates the likelihood of encountering other hikers (10 = complete solitude, 1 = crowded). Considers trail popularity, permit systems, and seasonal variations.

Wildlife Safety: Rates the presence of potentially dangerous wildlife (10 = minimal concerns, 1 = significant hazards). Primarily focuses on bears, mountain lions, and moose.

Permit Availability: Rates the ease of securing necessary permits (10 = no permits/easy to obtain, 1 = highly competitive lottery). Critical for planning trail access.

Seasonal Access: Rates the window of opportunity for hiking the trail (10 = year-round access, 1 = very limited season). Considers weather conditions, snow cover, and fire season. It ends up being roughly the number of months recommended to be on the trail each year.

Resupply Options: Rates the availability of food and supply replenishment (10 = frequent options, 1 = no options). Important for longer trails to minimize carried weight.

Trailhead Access: Rates the ease of reaching the starting point (10 = easy access via paved roads, 1 = difficult remote access). Considers transportation options and road conditions.

These metrics allow hikers to quickly assess which trails align with their capabilities, preferences, and available time. For all ratings, higher numbers (closer to 10) indicate more favorable conditions for hikers, while lower numbers (closer to 1) indicate more challenging or demanding conditions.

Now get out there on the trail and experience the natural bounty that America has to offer!
