The answer to “What is the longest hiking trail in the world?” depends on what counts as a hiking trail. Guinness World Records currently lists the Pacific Crest Trail as the world’s longest designated hiking trail. The Appalachian Trail, meanwhile, is recognized by the Appalachian Trail Conservancy as the world’s longest hiking-only footpath. Even longer recreational routes exist, but they fall into different categories.
Quick Answer
Guinness World Records lists the Pacific Crest Trail as the world’s longest designated hiking trail at about 2,650 miles (4,260 km). The Appalachian Trail is shorter at 2,197.9 miles in 2026, but the Appalachian Trail Conservancy calls it the world’s longest hiking-only footpath.
Key Takeaways
- Guinness World Records recognizes the Pacific Crest Trail as the longest designated hiking trail.
- The PCTA’s January 2026 GIS data estimates the PCT at 2,655.84 miles, although 2,650 miles remains the standard rounded figure.
- The Appalachian Trail is 2,197.9 miles in 2026 and is described by the Appalachian Trail Conservancy as the world’s longest hiking-only footpath.
- The 28,000-km Trans Canada Trail is much longer, but it is a multi-use network containing land and water routes rather than one hiking-only footpath.
- Long-distance hikers must plan for permits, changing weather, water treatment, food storage, wildlife, closures, resupply, and months of sustained physical effort.
Which Trail Is Actually the Longest?
There is no useful answer without defining the category. Trail organizations use terms such as designated hiking trail, hiking-only footpath, hiking route, and recreational trail network differently.
| Trail or Route | Approximate Length | What the Record Means |
| Pacific Crest Trail | About 2,650 miles; PCTA’s 2026 GIS estimate is 2,655.84 miles | Guinness World Records lists it as the world’s longest designated hiking trail. |
| Appalachian Trail | 2,197.9 miles in 2026 | ATC describes it as the world’s longest hiking-only footpath. |
| Sentiero Italia CAI | About 7,900–8,000 km (roughly 4,900–5,000 miles) | CAI describes it as one of the world’s longest hiking routes, divided into more than 500 stages across mainland Italy and major islands. |
| Trans Canada Trail | More than 28,000 km (about 17,400 miles) | The world’s longest trail network; it is multi-use and includes both land and water routes. |
Note: Trail-length records can appear contradictory because organizations are measuring different things. A continuous hiking-only footpath, a designated hiking trail, and a nationwide network of roads, waterways, greenways, and footpaths are not identical categories.
Why the Appalachian Trail Still Holds a World Record
The Appalachian National Scenic Trail runs from Springer Mountain in Georgia to Katahdin in Maine and crosses 14 states. The Appalachian Trail Conservancy gives its official 2026 length as 2,197.9 miles and describes it as the world’s longest hiking-only footpath.
A typical thru-hike takes around six months. Northbound hikers commonly start in Georgia between late February and early April, then aim to reach Katahdin before seasonal conditions close summit access in autumn.
The Appalachian Trail recorded about 16.9 million recreation visits in 2025, and more than 3,000 people attempt to thru-hike the entire footpath in a typical year, according to the Appalachian Trail Conservancy.
History and Development of the Trail
The Appalachian Trail began with forester and regional planner Benton MacKaye. In October 1921, his article, “An Appalachian Trail: A Project in Regional Planning,” proposed a long-distance route through the Appalachian Mountains. His idea went beyond recreation. He saw the trail and surrounding landscape as a way for people to reconnect with nature and as part of a broader regional-planning vision.
Trail construction gathered momentum through volunteer hiking clubs. The Appalachian Trail Conference, now known as the Appalachian Trail Conservancy, was established in 1925 to coordinate the effort. Myron Avery later pushed construction forward by organizing trail clubs, mapping routes, clearing and marking the footpath, and publishing trail information.
The Civilian Conservation Corps and other state and federal partners also contributed to construction during the 1930s. The route was fully connected from Maine to Georgia in 1937, although hurricanes, development, land acquisition, and later relocations changed the route many times afterward.
The trail became one of the first National Scenic Trails under the National Trails System Act in 1968. Its exact distance still changes slightly from year to year as sections are relocated or measured more precisely.
Trail Highlights and Points of Interest
The Appalachian Trail passes through a remarkable range of eastern U.S. landscapes, from the southern Appalachians to the rugged mountains of New England.
Katahdin and Baxter State Park
Katahdin, Maine’s tallest mountain, is the A.T.’s northern terminus and sits inside Baxter State Park. For northbound thru-hikers, reaching the summit is the symbolic end of a journey that normally began more than 2,000 miles earlier at Springer Mountain.
The climb is demanding, exposed in places, and governed by Baxter State Park rules. Hikers planning to finish there should review the current ATC Katahdin guidance before arriving.
Great Smoky Mountains National Park
The A.T. crosses Great Smoky Mountains National Park along the Tennessee–North Carolina border. Its elevation changes, dense forests, misty ridges, and biodiversity make it one of the trail’s best-known sections.
The National Park Service reported more than 22,000 identified species in the park as of 2025. Researchers believe many more remain undocumented. Hikers may pass hardwood forests, high-elevation spruce-fir communities, wildflowers, streams, historic sites, and wildlife habitat within the park.
The Blue Ridge and Other Scenic Sections
The Appalachian Mountains offer long ridge walks, rocky viewpoints, forested gaps, streams, and seasonal displays of fall color. Famous A.T. areas include Shenandoah National Park, McAfee Knob, the White Mountains, the Great Smokies, and the mountains of Maine.
Linville Falls is another famous North Carolina waterfall sometimes associated with Appalachian travel, but it is not an Appalachian Trail landmark. The National Park Service places Linville Falls along the Blue Ridge Parkway near milepost 316, so visiting it requires a separate side trip rather than simply following the A.T.
Challenges and Considerations for Hiking the Trail
| Challenge | What to Consider |
| Physical Endurance | Train gradually, test your footwear and pack, and avoid pushing through pain caused by overuse. |
| Weather Conditions | Carry appropriate rain, insulation, and emergency layers. Mountain conditions can change quickly. |
| Navigation | Use current maps or trail data and carry a backup navigation method rather than relying on one phone or GPS device. |
| Wildlife Encounters | Keep a clean camp, never feed wildlife, and store food, trash, and scented items securely. |
| Water and Food Supply | Plan resupply stops and water carries carefully. Natural water sources can be seasonal and should be treated before use. |
| Permits and Closures | Check current regulations, permit requirements, closures, fires, storm damage, bridge outages, and detours before each section. |
The A.T. may be well marked, but that does not make it easy. Long climbs, rocky descents, wet roots, mud, heat, cold rain, snow, river crossings, and prolonged fatigue can all become serious problems. Many sections are remote enough that hikers must manage their own food, water, shelter, navigation, and emergency planning.
Warning: Backcountry conditions change constantly. Check the ATC Trail Updates page and the managing park or forest before leaving. Do not enter closed sections simply because a trail appears passable.
Permits and Camping Rules
Most of the Appalachian Trail does not require one trail-wide permit, but specific protected areas do. The ATC currently identifies permit requirements in Great Smoky Mountains National Park, Shenandoah National Park, and Baxter State Park. Camping, shelter, fire, parking, and food-storage rules also vary by location.
Review the current Appalachian Trail permit and fee guidance instead of relying on an old trip report or guidebook.
Water Treatment
Natural springs and streams are the main water sources for many backpackers, but clear water is not automatically safe water. The ATC recommends treating or filtering water before using it for drinking, cooking, or cleaning because microorganisms such as Giardia can be present.
Water availability also changes with weather and season. A source marked on a map may be weak or dry after a prolonged dry period, so hikers should check recent reports and carry enough capacity for the section ahead.
Bears and Food Storage
Black bears live along much of the A.T. The most important preventive steps are keeping a clean camp and preventing bears from getting human food. Store food, trash, and scented items according to local rules and never keep them loose in your tent.
The Appalachian Trail Conservancy currently recommends hard-sided bear canisters for overnight hikers as the most reliable food-storage method on the A.T. Some locations also have specific food-storage requirements, so check the rules for every section you plan to visit.
Leave No Trace
Hikers should stay on established tread, avoid cutting switchbacks, use durable campsites, pack out trash, dispose of human waste correctly, respect wildlife, and follow local fire restrictions. These actions reduce erosion, wildlife conflicts, campsite expansion, and damage caused by millions of visits.
Wildlife and Natural Features Along the Trail
The Appalachian Trail crosses a wide range of habitats. Black bears, white-tailed deer, wild turkeys, salamanders, snakes, and many bird species live within or near its corridor. Hawks and other raptors may be visible from open ridges, while warblers are common in forested sections during migration and breeding seasons.
Wildlife should be observed from a safe distance. Feeding animals or leaving food unsecured can change their behavior and create dangerous situations for both wildlife and hikers.
The trail also showcases changing geology and vegetation from Georgia to Maine. Southern hardwood forests give way to higher, colder mountain environments as hikers travel north. Rocky ridges, streams, balds, spruce-fir forests, exposed alpine terrain, and long mountain views keep the landscape varied across nearly 2,200 miles.
The Blue Ridge Mountains are especially colorful in autumn, when deciduous forests turn shades of red, orange, and yellow. Farther north, New Hampshire’s White Mountains and the mountains of Maine introduce rougher rock, exposed terrain, and severe weather that can make the final portion of a northbound thru-hike especially demanding.
Tips and Advice for Hiking the Longest Trail
Very few people should make a multi-month thru-hike their first backpacking trip. Start with day hikes, then overnight trips, then multi-day sections. This gives you time to learn how your footwear, pack, shelter, sleep system, clothing, food, and body perform in real conditions.
- Train consistently: Walking with a loaded pack is more useful than relying only on gym workouts.
- Test your footwear: Shoes or boots that feel fine for five miles may cause trouble after repeated 15- to 20-mile days.
- Keep pack weight reasonable: Carry what you need for safety without packing unnecessary duplicates.
- Plan resupply: Know where you can leave the trail for groceries, fuel, lodging, medical care, and replacement gear.
- Treat drinking water: Carry a dependable filtration or treatment method and a backup appropriate to your trip.
- Carry navigation: A phone app is useful, but batteries fail and electronics can be damaged or lost.
- Check conditions repeatedly: Weather, wildfire, flooding, storm damage, bridge closures, and bear activity can change an itinerary.
- Listen to your body: Overuse injuries are common on long-distance hikes. Rest early rather than turning a minor problem into a trip-ending injury.
Pro Tip: Build flexibility into your itinerary. Extra time makes it easier to wait out dangerous weather, recover from soreness, adjust mileage, handle a closure, or make an unexpected gear replacement without feeling forced to take unnecessary risks.
Food should be calorie-dense, easy to prepare, and practical to carry. Nuts, dried fruit, energy bars, tortillas, nut butter, dehydrated meals, and similar foods are popular because they provide substantial energy without excessive bulk. Longer hikers normally resupply repeatedly rather than carrying months of food at once.
Phones, GPS devices, headlamps, cameras, and satellite communicators also create charging needs. A power bank is often the simplest option, while solar performance can vary with tree cover and weather. Hikers considering solar charging can review this guide to the best solar charger for backpacking when deciding whether one fits their route and electronics setup.
Personal Experiences and Stories from Hikers
The appeal of the Appalachian Trail goes far beyond mileage. A thru-hiker repeats the same basic cycle for months: walk, find water, eat, make camp, sleep, resupply, and start again. That simple routine can make weather, terrain, small comforts, trail towns, and encounters with other hikers feel unusually significant.
The trail’s social side is equally important. People who begin as strangers often see one another repeatedly at shelters, campsites, road crossings, and resupply towns. Hikers use trail names, share weather and water information, help one another solve gear problems, and form informal groups as their pace changes.
The statistics also show how difficult a complete hike can be. The Appalachian Trail Conservancy recorded a 25% completion rate among northbound thru-hike attempts in its 2025 counts. Some hikers leave because of injury, illness, finances, weather, family obligations, or simply because a multi-month hike no longer matches what they want.
Finishing is therefore only one way to experience the trail. Section hikers may complete it over several years, while millions of other visitors enjoy day hikes, weekends, or shorter backpacking trips without attempting all 2,197.9 miles at once.
Conclusion and Future of the Longest Hiking Trail
The phrase “longest hiking trail in the world” sounds simple, but the accurate answer depends on the category. Guinness World Records recognizes the Pacific Crest Trail as the longest designated hiking trail, while the Appalachian Trail holds a separate distinction as the world’s longest hiking-only footpath according to the Appalachian Trail Conservancy. Longer routes and networks, including Sentiero Italia and the Trans Canada Trail, show why defining the term matters.
The Appalachian Trail itself remains an extraordinary conservation and recreation corridor. Its future depends on maintaining the footpath, responding to storm and climate impacts, protecting surrounding ecosystems, managing heavy use, reducing wildlife conflicts, and keeping hikers informed about changing conditions.
Technology can make long-distance hiking easier through better maps, weather information, emergency communication, and lighter equipment. It should complement rather than replace basic backcountry skills. A charged phone cannot make unsafe water drinkable, reopen a closed trail, or substitute for sound decisions when mountain weather deteriorates.
Whether someone hikes the whole A.T., attempts the PCT, completes a few sections, or spends one afternoon on a local stretch, the same principles apply: prepare carefully, respect the land, follow current regulations, and adjust plans when conditions demand it.
Frequently Asked Questions
What is the longest hiking trail in the world?
Guinness World Records currently lists the Pacific Crest Trail as the world’s longest designated hiking trail at 4,260 km, or about 2,650 miles. The Pacific Crest Trail Association’s January 2026 GIS data gives a more precise current estimate of 2,655.84 miles. The Appalachian Trail holds a different distinction: the Appalachian Trail Conservancy calls its 2,197.9-mile route the world’s longest hiking-only footpath.
How long does it take to hike the entire Pacific Crest Trail?
The Pacific Crest Trail Association says an average thru-hike takes about five months. Roughly 4.5 to 5.5 months is common, depending on daily mileage, rest days, snow, wildfire closures, injuries, and other conditions. Very fast completions are possible but are not realistic benchmarks for most hikers.
What are the main highlights along the Pacific Crest Trail?
The PCT crosses Southern California desert landscapes, the Sierra Nevada, forests of Northern California and Oregon, and the volcanic and alpine scenery of the Cascade Range in Washington. The route passes through a dramatic range of climates and ecosystems between the Mexican and Canadian borders.
Are there dangerous sections along the Pacific Crest Trail?
Yes. Hazards can include extreme heat, scarce water, lingering mountain snow, steep snow traverses, high stream crossings, thunderstorms, wildfire and smoke, falling trees in burned areas, cold rain, and early-season or late-season winter conditions. Hikers should check current PCTA closures and agency information instead of assuming that a previous year’s route is open or safe.
Are permits required for hiking the Pacific Crest Trail?
Permit requirements depend on the trip. For a continuous PCT journey of 500 miles or more, hikers and equestrians can apply for the interagency PCT Long-distance Permit issued by the Pacific Crest Trail Association under U.S. Forest Service authority. Many individual wilderness areas also have their own permit systems, so shorter trips may require local permits.
Why is the Appalachian Trail called the longest hiking-only footpath?
The Appalachian Trail Conservancy uses “hiking-only footpath” as a specific category and describes the A.T. as the world’s longest route of that type. It extends 2,197.9 miles in 2026 from Springer Mountain, Georgia, to Katahdin, Maine. That category is different from Guinness’s “longest designated hiking trail” record for the PCT.
Is the Trans Canada Trail longer than the PCT and Appalachian Trail?
Yes in total network length. The Trans Canada Trail spans more than 28,000 km, making it the world’s longest trail network. However, it is a multi-use system made from many connected trails and includes land and water routes, so it is not the same type of single designated hiking trail measured by the Guinness PCT record.
