The Flint Hills Trail stretches for 117 miles* across east-central Kansas, from Osawatomie in the east to Herington in the west, and passes through communities including Rantoul, Ottawa, Pomona, Vassar, Osage City, Miller, Admire, Allen, Bushong, and Council Grove. The trail passes through five counties: Miami, Franklin, Osage, Lyon, and Morris.
The Prairie Spirit Trail in eastern Kansas is a 52 1/2 mile path through small towns, shaded woodland canopy, and scenic prairies alive with wildflowers (and wildlife!), and running beside streams, rivers, neatly-tended fields and family farms. Built on the railbed of the old Leavenworth, Lawrence and Fort Gibson Railroad, the trail offers easy grades for hikers and bikers alike.

Construction of the “Berlin Wall Trail” (Berliner Mauerweg) began in 2002 and was completed in 2006.
Nevado Ojos del Salado (6893m) is the second highest peak in South America. It is on the border between Chile and Argentina, and can be climbed from either side.
From the Chile side, the logical start point is the large Refugio Claudio Lucero (a.k.a. Refugio Murray), at 4527m, or from the Atacama Base Camp at 5250m. From there it is about 27km with 2366m of elevation gain to the top. Permanent mountain refuges are built on most camps and are reachable in 4x4 vehicles.
