throughhiking

Throughhiking is the practice of hiking a long-distance trail from end to end in a single continuous journey. It is commonly associated with established trails in the United States, such as the Appalachian Trail, Pacific Crest Trail, and Continental Divide Trail, but it also applies to other long-distance routes worldwide. A through-hike typically lasts several months and requires careful planning and sustained endurance. A hiker who completes an entire trail in one continuous attempt is called a through-hiker.

Notable through-hikes include the Appalachian Trail in the eastern United States, about 2,190 miles (3,520 km) from Georgia to Maine; the Pacific Crest Trail along the West Coast, about 2,650 miles (4,265 km) from Mexico to Canada; and the Continental Divide Trail, roughly 3,100 miles (4,990 km) along the Rocky Mountains. International examples include the Te Araroa in New Zealand. Many other countries offer long-distance routes that are popular for through-hiking as well.

Planning and logistics are central to a successful through-hike. Hikers typically use lightweight gear, plan for frequent resupply, and adapt to variable weather and terrain. Permits or quotas may apply on some trails or segments, and backcountry restrictions or timing considerations can influence itineraries. Support systems exist in many trail communities and at trail towns, including services, mail drops, and “trail magic” encounters. Practice and etiquette emphasize Leave No Trace, respect for wildlife, and minimal impact on ecosystems.

Through-hiking fosters a distinct culture and vocabulary, including terms like through-hiker, section hiker, and zero days. It is a demanding form of long-distance travel that emphasizes endurance, preparation, and a connection to backcountry landscapes.
