Types of Hikes
Northbound (NOBO)

Typical Start: March–April
Advantages:
- Most social experience
- Largest support network
- Many hikers following the same schedule
Challenges:
- Crowded shelters and campsites
- Greater competition for services during peak season
Southbound (SOBO)
A southbound hike begins at Mount Katahdin in Maine and ends at Springer Mountain in Georgia.
Typical Start: June–July
Advantages:
- Smaller crowds
- Greater solitude
- Cooler temperatures during the southern portion of the hike
Challenges:
- Katahdin and the White Mountains are encountered immediately
- Shorter hiking season
- Fewer fellow thru-hikers
Flip-Flop
A flip-flop hike begins somewhere in the middle of the trail. Hikers complete one half of the trail, then travel to the opposite end and hike the remaining section.
Advantages:
- Flexible scheduling
- Can avoid crowded sections
- May provide more favorable weather conditions
Challenges:
- Requires additional travel logistics
- Different experience from a continuous end-to-end hike
Trail Culture
The Appalachian Trail has its own culture, customs, and shared language. Many of these traditions developed over decades as hikers, volunteers, trail towns, and local communities shaped the experience of the trail.
Trail Names
Many long-distance hikers use trail names instead of their regular names while hiking. A trail name may come from something funny, memorable, personal, or unexpected that happens on the trail.
Trail Angels
Trail angels are people who help hikers through acts of kindness. They may offer rides, food, water, encouragement, lodging, or other support.
Trail Magic
Trail magic is an unexpected act of generosity along the trail. It might be a cooler full of drinks at a road crossing, a meal offered by a stranger, or help getting into town.
Hiker Boxes
Hiker boxes are places where hikers leave extra food, gear, fuel, or supplies for other hikers. They are often found at hostels, outfitters, and other hiker-friendly locations.
Shelter Etiquette
Shelter etiquette helps hikers share limited space respectfully. Common expectations include making room for others, keeping gear organized, controlling noise, and respecting those who want to sleep.
Leave No Trace
Leave No Trace principles help protect the trail and surrounding wilderness. Hikers are expected to pack out trash, minimize impact, respect wildlife, and leave campsites better than they found them.
Shelters and Camping
Appalachian Trail hikers use a mix of shelters, tents, hammocks, hostels, and occasional lodging in trail towns. Understanding how camping works on the AT helps hikers plan safer and more comfortable days.
Appalachian Trail Shelters
Many sections of the Appalachian Trail have three-sided wooden shelters located near the trail. These shelters are usually first-come, first-served and may include nearby tent sites, water sources, and privies.
Tent Camping
Many hikers carry tents and camp near shelters, designated campsites, or other approved areas. Tenting provides more privacy and flexibility than sleeping inside a shelter.
Hammock Camping
Some hikers use hammocks instead of tents. Hammocks can work well in wooded areas, but they require appropriate suspension straps, insulation, and awareness of local rules.
Water Sources
Water planning is a daily part of AT hiking. Hikers often check the distance between reliable water sources before deciding where to camp.
Food Storage
Proper food storage helps protect hikers and wildlife. Depending on the location, hikers may use bear cables, bear boxes, bear canisters, or food hangs.
Privies
Many shelter areas include privies. They help reduce environmental impact and keep campsites cleaner.
Shelter Etiquette
Shelters are shared spaces. Hikers are expected to make room for others, keep gear organized, control noise, avoid cooking inside the shelter, and respect quiet hours.
Trail Towns
Trail towns are communities near the Appalachian Trail where hikers can rest, resupply, do laundry, shower, eat a real meal, and recover before returning to the trail.
Resupply
Resupply means obtaining food, fuel, and other supplies needed for the next section of trail.
Hostels
Many trail towns have hiker-friendly hostels that offer bunks, showers, laundry, charging stations, shuttles, and a place to rest.
Shuttle Services
Some towns are not directly on the trail, so hikers may use shuttle drivers to get between the trailhead and town.
Restaurants and Grocery Stores
Food is a major part of trail-town life. After days on the trail, restaurants and grocery stores become important morale stops.
Zero Days
A zero day is a day when a hiker does not hike any trail miles. Zero days are often used for rest, laundry, resupply, and recovery.
Nero Days
A nero, or near-zero day, is a short hiking day. A hiker may hike only a few miles before entering town or leaving town.
Notable Trail Towns
Some well-known Appalachian Trail towns include:
- Damascus, Virginia
- Hot Springs, North Carolina
- Harpers Ferry, West Virginia
- Hanover, New Hampshire
- Monson, Maine
