When hikers ask which trails in Missouri 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 Missouri by total mapped distance, drawing from the 7,319 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.
Missouri straddles the Ozark Plateau in the south — clear-running rivers, sandstone bluffs, and dolomite karst — and the rolling glaciated plains in the north. The Ozark Trail dominates Missouri long-distance mileage; the Berryman Trail and Ozark Highlands Connector add complementary routes. Spring and fall are best; summer is humid and tick-heavy; winter trails are quiet but ice-prone in shaded ravines.
Our rankings here are data-driven — pulled from the 7,319 mapped entries OutsideAtlas tracks in Missouri — 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.

#1. Federer’s Folly Trail
At 0.80 mi, Federer’s Folly Trail tops the list — a route built for hikers who plan in days, not hours. Expect 0.80 mi, compacted 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. 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.

A few pieces of context are worth keeping in mind specifically for Missouri. Spring and fall are best; summer is humid and tick-heavy; winter trails are quiet but ice-prone in shaded ravines. Copperheads and rattlesnakes in the Ozarks, ticks across the state, and flash floods in narrow river canyons after thunderstorms.
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.
