Inca Trail, Peru
While there are other trails that can get you to the famous archaeological ruins of Machu Picchu, none or more famous than the Inca Trail. While you can get to the mythical citadel without making the trek, you will miss out on imposing mountain passes, snowcapped peaks visible along the route, cloud forest high in the Andes and the opportunity to walk in the footsteps of the Inca. The three- to four-day trek can only be done with an approved outfitter, and there are limits on the number of people allowed on the trail daily. Plan early as slots fill up fast.
Kilimanjaro, Tanzania
Climbing to the rooftop of Africa can be a daunting task. While multiple routes exist to summit the continent’s highest peak (19,340 feet), the Machame and Marangu routes are the most popular. The trek can take between seven and eight days depending on the route and will take you through a multitude of ecosystems from tropical jungle to glacial snowfields on your way to the summit. If you desire to see the snow atop the peak, you better hurry as they are expected to be completely gone within the next decade.
