Georgia to Maine, United States
2,200 miles/3,500 km
Best time to go: Springtime.
Northbound trekkers leave late March to mid-April; southbound starts late May to mid-June. This swath of trail cruises through 14 states, with a quarter of the journey cutting through Virginia. If you're eager to try a long trek but want to be able to pop into town on a regular basis for a candy bar or shower, this is the hike for you. You can sleep in the 260 shelters along the way, but a tent or hammock will help you escape the crowds and have a bit of privacy. Most trekkers set aside 5 to 7 months for the journey, though Karel Sabbe set the speed record for the Appalachian Trail in 41 days, 7 hours and 39 minutes.
Camino de Santiago
Saint Jean Pied de Port, France, to Galicia, Spain
500 miles/804 km
Best time to go: April and May
This isn't just a hike, it's a religious pilgrimage that winds through the Pyrenees Mountains, past vineyards and into eucalyptus forests. It's named for Saint James, an apostle believed to be buried beneath the Cathedral of Santiago de Compostela. In the ninth century, pilgrims would walk to the apostle's resting place to ask forgiveness for their sins. Today, the route goes right by lodging and restaurants so don't feel pressured to carry too much.
Everest Base Camp
Khumbu region, Nepal
80.7 miles/129 km
Best time to go: Spring (February to May) or fall (September to October)
This is one of the most famous treks in the world for good reason. Reaching a height of 18,193 feet, this trek brings visitors through the majestic Himalayas to stand at the base of the highest mountain in the world. There is no shortage of quaint mountain villages, impressive peaks and friendly Sherpa people along the way. The distance isn't as daunting as others, but the altitude is, so be sure to trek slow and allow yourself time to acclimate.
South Island, New Zealand
20 miles/32 km
Best time to go: late May to early October
This epic alpine adventure goes through the Southern Alps and two national parks, stealing your breath with the stunning scenery. Think massive valleys, waterfalls and soaring peaks with the occasional stop at refreshing lakes. It is not a loop so feel free to start from either end. But reserve a spot sooner than later because permits can be hard to come by!
26 miles/43 km
Best time to go: May to September
This ancient trail leads to Machu Picchu, a mysterious city of stone built by the Incas without the aid of iron tools or wheels. Although it was constructed in the 15th century, hikers didn't begin flocking to the hilltop citadel until 1911 when Hiram Bingham "discovered" it. The trail begins in Sacred Valley and winds its way through the mountains, crossing three high passes before arriving at 7,970 feet (2,430 meters). Don't be in a hurry to get there though. Along the way you'll experience cloud forests, jungles, sweeping views of the Andes and an array of archaeological sites. A permit is necessary -- only 200 hikers are allowed each day.
Length: 112 miles/180 km
Best time to go: Mid-June to early September
This journey will take you through brilliantly painted hills in the Highlands of Iceland with lava fields stretching across valleys and hot springs to soak your tired muscles. One of the highlights is the misleadingly named "Ugly Puddle," a small crater lake boasting sparkling blue water, neon green moss and red lava rock. High-end campgrounds or mountain huts - it's your choice.
Tour du Mont Blanc
France, Switzerland, Italy
Length: 110 miles/ 170 km
Best time to go: June to August
Dying to see Mont Blanc but don't want to climb it? This breathtaking trek circumnavigates the 15,781-foot mountain, which is the highest in Western Europe. You'll cross through three countries with lots of ups and downs (think 32,000 feet or 10,000 meters of elevation gain) but the unbeatable views of the Alps and alpine charm will distract you from the pain. There are homey refuges dotted along the trail that offer a bed or home cooked meals to keep your load light.
Torres del Paine
Length: 80 miles/130 km
Best time to go: December to February
This is a place dreams are made of. Dramatic granite spires, sparkling lakes and vast glaciers fill the park and offer endless photo ops. The hiking isn't too tough but the weather is known for being unpredictable. Brace yourself for the possibility of cold temperatures and high winds no matter what time of year you go. You have the choice of camping on your own or staying in huts along the way.
