Tianzi Mountains, China

Hundreds of waters and thousands of peaks are in the Tianzi Mountains. What an uncanny work of art by Nature. The highest peak of the mountains is 1262.5 meters above sea level. Around it is rolling ridges and peaks and high picturesque rocks. On the top of the mountains, one can have a bird's eye view of numberless inter winding hills and deep valleys of the Wulingyuan area as well as downpouring waterfalls and lofty old pines in drifting mists and clouds. There are different sights when seasons and weather change, Sometimes it is fine with blue sky, which gives one a sense of strength and vastness. Sometimes it is full or clouds and mists, which gives one a sense of mystery of if in fairyland.

Twelve Apostles, Australia

Witness the rugged splendour of the famous 12 Apostles, magnificent rock stacks that rise up majestically from the Southern Ocean on Victoria’s dramatic coastline. Created by constant erosion of the limestone cliffs of the mainland beginning 10-20 million years ago, the stormy Southern Ocean and blasting winds gradually eroded the softer limestone, forming caves in the cliffs.The caves eventually became arches and when they collapsed rock stacks up to 45 metres high were left isolated from the shore.

Ha Long Bay, Vietnam

Halong Bay is one of the world’s natural wonders, and is the most beautiful tourist destination of Vietnam. Halong Bay features more than one thousand awesome limestone karsts and islands of various sizes and shapes along the 120-km coastline of Bai Chay Beach. Its waters are host to a great diversity of ecosystems including offshore coral reefs, freshwater swamp forests, mangrove forests, small freshwater lakes, and sandy beaches. The folk tale has it that the dragons descended from heaven to help locals by spitting jewels and jade to the sea, forming a natural fortress against invaders; these precious stones are represented by the lush green outcrops. Several islands boast beautiful grottos and caves with contiguous chambers, hidden ponds and peculiar stone formations.

Pamukkale, Turkey

Pamukkale, meaning “cotton castle” in Turkish, is a natural site in Denizli Province in southwestern Turkey. The city contains hot springs and travertines, terraces of carbonate minerals left by the flowing water. It is Turkey’s foremost mineral-bath spa because of its natural beauty: hot calcium-laden waters spring from the earth and cascade over a cliff. As they cool they form dramatic travertines of hard, brilliantly white calcium that form pools.

Monument Valley, USA

Monument Valley (Navajo: Tsé Biiʼ Ndzisgaii, meaning valley of the rocks) is a region of the Colorado Plateau characterized by a cluster of vast sandstone buttes, the largest reaching 1,000 ft (300 m) above the valley floor. Monument Valley provides perhaps the most enduring and definitive images of the American West. The isolated red mesas and buttes surrounded by empty, sandy desert have been filmed and photographed countless times over the years for movies, adverts and holiday brochures. Because of this, the area may seem quite familiar, even on a first visit, but it is soon evident that the natural colors really are as bright and deep as those in all the pictures. The valley is not a valley in the conventional sense, but rather a wide flat, sometimes desolate landscape, interrupted by the crumbling formations rising hundreds of feet into the air, the last remnants of the sandstone layers that once covered the entire region.

Petra, Jordan

Petra, the world wonder, is without a doubt Jordan’s most valuable treasure and greatest tourist attraction. It is a vast, unique city, carved into the sheer rock face by the Nabataeans, an industrious Arab people who settled here more than 2000 years ago, turning it into an important junction for the silk, spice and other trade routes that linked China, India and southern Arabia with Egypt, Syria, Greece and Rome.

The Wave, Arizona, USA

The Wave is a sandstone rock formation located in the United States of America near the Arizona and Utah border on the slopes of the Coyote Buttes, in the Paria Canyon-Vermilion Cliffs Wilderness, on the Colorado Plateau. Nearly 200 million years ago, this region was a sandy desert where huge dunes migrated across the landscape pushed by seasonal winds. Prevailing winds of that ancient Jurassic time can be determined by examining the cross-bedding (layers) in the sandstone.

 What we see today are some of the original crossbedded dunes shaped into dramatic landforms and exposed by erosion from eons of runoff. The spectacular ribbons of various colors called Liesegang Bands, were formed by movement and precipitation of oxidizing materials such as iron and manganese by ground water. Thin veins or fins of calcite cut across the sandstone, adding another dimension to the landscape.
