When hikers ask which trails in Alaska are worth a full day — or several — the conversation always circles back to the same handful of routes. Below we've ranked the ten longest hiking trails in Alaska by total mapped distance, drawing from the 5,707 trails OutsideAtlas currently tracks in the state. Each entry includes the distance, what makes the route distinctive, and an honest note on who should actually attempt it.
Alaska is the most physically extreme hiking environment in the US — glacier-carved fjords, active volcanoes, vast tundra, and the highest peaks on the continent. Alaska's mapped long trails are often routes through wilderness rather than constructed paths — distance figures can understate effort dramatically. Summer (mid-June through August) is the only practical season for most routes; even then, snowfields linger above 3,000 feet.
Our rankings here are data-driven — pulled from the 5,707 mapped entries OutsideAtlas tracks in Alaska — but the data has limits worth being honest about. OpenStreetMap distance tags are crowd-sourced and inconsistent. A route may appear longer or shorter than the official measurement, especially when long-distance trails (like state and national scenic trails) are tagged in segments rather than as a single relation.
The Ranking
Ranked from #1 to #10. Click through any entry for the full trail page — map, elevation profile, weather forecast, and direct OpenStreetMap source link.
#1. Little Coal Creek Trail
Little Coal Creek Trail earns the #1 spot for its sheer distance, though the exact mileage in OpenStreetMap data is a rough estimate. Expect 2,953 ft of gain on a forgiving grade. Local trail-association reports tend to agree this is one of the better-maintained options in the area, which matters more on a hike of this length than on a quick walk. Plan as a multi-day if you're not used to single-push 20+ mile days; resupply or shuttle logistics matter here. See full trail details, map, and current weather on OutsideAtlas for the most current information.

Ermine Hill Trail earns the #2 spot for its sheer distance, though the exact mileage in OpenStreetMap data is a rough estimate. Expect 4,265 ft of gain on a forgiving grade. The route is well documented in OpenStreetMap, which is what put it on our radar — community-mapped routes tend to be the ones that get hiked enough to stay open. Plan as a multi-day if you're not used to single-push 20+ mile days; resupply or shuttle logistics matter here.

Yeager's Cabin Connector to Wickersham Summit Trail earns the #3 spot for its sheer distance, though the exact mileage in OpenStreetMap data is a rough estimate. Expect unpaved surface on a genuinely demanding grade. It earns its ranking on the data, but trail conditions can change quickly after storms or fire seasons, so verify before you commit a full day. A paved surface makes this one of the more accessible options on the list — good for strollers, mobility aids, and wet-weather days. Plan as a multi-day if you're not used to single-push 20+ mile days; resupply or shuttle logistics matter here.

Yeager's Cabin Connector to Wickersham Creek Trail earns the #4 spot for its sheer distance, though the exact mileage in OpenStreetMap data is a rough estimate. Expect unpaved surface on a forgiving grade. Compared to similar trails in Alaska, this route trades difficulty for either solitude or scenery — sometimes both. A paved surface makes this one of the more accessible options on the list — good for strollers, mobility aids, and wet-weather days. Plan as a multi-day if you're not used to single-push 20+ mile days; resupply or shuttle logistics matter here.

Iditarod National Historic Trail (Northern route) earns the #5 spot for its sheer distance, though the exact mileage in OpenStreetMap data is a rough estimate. Expect ground surface on a forgiving grade. What makes this one earn its spot on the list is the combination of mapped detail and the kind of through-and-through experience that justifies a longer drive. The natural-surface tread can get slick after rain and muddy in spring — pick a dry weather window if you have the flexibility. Plan as a multi-day if you're not used to single-push 20+ mile days; resupply or shuttle logistics matter here.

Iditarod National Historic Trail (Southern route) earns the #6 spot for its sheer distance, though the exact mileage in OpenStreetMap data is a rough estimate. Expect ground surface on a forgiving grade. Local trail-association reports tend to agree this is one of the better-maintained options in the area, which matters more on a hike of this length than on a quick walk.

Mount Dewey Spur Trail (Shachk Kinaa Deiyi Trail) earns the #7 spot for its sheer distance, though the exact mileage in OpenStreetMap data is a rough estimate. Expect gravel surface on a forgiving grade. The route is well documented in OpenStreetMap, which is what put it on our radar — community-mapped routes tend to be the ones that get hiked enough to stay open. A gravel-and-dirt tread holds up well after rain, though loose surface on descents calls for trekking poles or careful footing. Plan as a multi-day if you're not used to single-push 20+ mile days; resupply or shuttle logistics matter here.

Cottonwood Trail - Summer (hiking) or Winter only (ski/Snowshoe) earns the #8 spot for its sheer distance, though the exact mileage in OpenStreetMap data is a rough estimate. Tagged easy in OpenStreetMap. It earns its ranking on the data, but trail conditions can change quickly after storms or fire seasons, so verify before you commit a full day.

A few pieces of context are worth keeping in mind specifically for Alaska. Summer (mid-June through August) is the only practical season for most routes; even then, snowfields linger above 3,000 feet. Bears (both grizzly and black), unbridged stream crossings, and rapidly changing weather are baseline hazards on any non-trivial route.
Always cross-reference the official land-manager page before driving out — closures, fire restrictions, and seasonal road access can change quickly. Our trail pages link directly back to the OpenStreetMap source so you can see the tags we're working from.
If you're new to hiking generally, our beginner's guide covers footwear, layering, and the day-pack basics. For safety planning on bigger objectives, the ten essentials guide is worth twenty minutes of reading.
