When hikers ask which trails in Oklahoma 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 Oklahoma by total mapped distance, drawing from the 37,280 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.
Oklahoma's Ouachita and Wichita Mountains, the Black Mesa in the panhandle, and the cross-timbers eastern forests produce more topographic variety than expected. The Ouachita Trail provides the bulk of Oklahoma's long-distance mileage; the Black Mesa Trail and Quartz Mountain routes add complementary terrain. Spring and fall are prime; summer is brutal across most of the state; winter brings ice storms.
Our rankings here are data-driven — pulled from the 37,280 mapped entries OutsideAtlas tracks in Oklahoma — 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. Oklahoma Highway Patrol Lieutenant Pat Grimes Memorial Bridge
Oklahoma Highway Patrol Lieutenant Pat Grimes Memorial Bridge earns the #1 spot for its sheer distance, though the exact mileage in OpenStreetMap data is a rough estimate. Expect asphalt 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. 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.

Clearbay Mountain Bike Trails (New Loop -- red/white) earns the #2 spot for its sheer distance, though the exact mileage in OpenStreetMap data is a rough estimate. Expect dirt surface on a forgiving grade.

The natural-surface tread can get slick after rain and muddy in spring — pick a dry weather window if you have the flexibility.

A few pieces of context are worth keeping in mind specifically for Oklahoma. Spring and fall are prime; summer is brutal across most of the state; winter brings ice storms. Tornadoes and lightning, copperheads and rattlesnakes, and serious heat-related illness in summer.
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.
