Kobuk Valley National Park in northwestern Alaska 25 miles (40 km) north of the Arctic Circle is noted for the Great Kobuk Sand Dunes and caribou migration routes. No roads lead to the park. People typically get there by chartered air taxi. Three sets of sand dune fields are located on the south side of the Kobuk River. The Great Kobuk Sand Dunes, Little Kobuk Sand Dunes and the Hunt River Dunes are remnants of dune fields that covered as many as 200,000 acres immediately after the retreat of Pleistocene glaciation. A combination of out-wash deposits from the glaciers and strong winds created the field, which is now mostly covered by forest and tundra.

The Stone Forest or Shilin is a notable set of limestone formations about 500 km2 located in Shilin Yi Autonomous County, Yunnan Province, People’s Republic of China.
The tall rocks seem to arise from the ground in a manner somewhat reminiscent of stalagmites, or with many looking like petrified trees, creating the illusion of a forest made of stone. According to legend, the forest is the birthplace of Ashima, a beautiful girl of the Yi people. After falling in love she was forbidden to marry her chosen suitor and instead turned into a stone in the forest that still bears her name.

The Grand Prismatic Spring in Yellowstone National Park, US, is known for its striking coloration and enormous size. The vivid colors in the spring are caused by bacteria, living on the edges of the mineral rich water. The water in the center of the pool looks extremely clear, and has a beautiful, deep-blue color – thanks to the scattering of blue wavelengths – because the water is so hot that’s actually sterile.

David Jarman, the British creator of Limit Zero, set up and created a zipwire ride connecting the Spanish village of Sanlúcar de Guadiana with Alcoutim, across the Guardiana River in Portugal.
Visitors are provided a unique experience crossing over the River Guadiana from Spain to Portugal. Along the 720 meters joining the two countries, users cross over the river at speeds between 70 and 80 kilometers per hour, literally flying through time and gaining one hour because of the time zone change between both countries.
Participants, when they reach the end of the zip line in Portugal, they walk to the Alcoutim jetty where they are ferried back across the river to Spain.
