Stuðlagil is a ravine in the Eastern Region of Iceland. It is known for its columnar basalt rock formations and the blue-green water that runs through it. It became an unexpected tourist sensation after being shown in a WOW air airline brochure in 2017. The rock formation is 30 meters tall.
The river Jökla runs through the ravine. The water level decreased by 7 to 8 meters due to the Kárahnjúkar Hydropower Plant, which opened in 2009.

Sail Rock is a natural sandstone monolith located on the shore of the Black Sea in Russia. It resembles the outline of a ship’s sail, hence its name. The monolith has a sheer vertical slope confronting the shore of the sea, isolated from the mass of basic rock by geological forces. It is more than three-fourths revealed by the tide and lies perpendicular to the coast. What is most remarkable about this landmark is its proportions. While the cliff is only a little more than one meter thick, its height is about 25 m and its length about 20.
An opening of unclear origin is located in the sail, approximately 2.5 meters above the ground. Many guides state that the formation was a defense against mountain artillery during the Caucasian War. However, this version of the origin of the opening is under some doubt. In 1903, S. Vasyukov, who was investigating the Black Sea coast, wrote after the inspection of the cliff that it was “[..] shot from a battleship by seamen, they released 4 projectiles, but the wall remained firm, although the traces are noticeable, but they nowhere opened the rock […]”.

Located at the foot of the Cuillin Mountains, the Fairy Pools are a natural waterfall phenomenon in Glen Brittle on the Isle of Skye. The pools are a vivid aqua blue and are a popular place for wild swimmers who brave the frigid waters.
The habitat of the Fairy Pools hosts a variety of animals and a large number of birds. The physical landscape is predominately rocky, with some boggy areas here and there. The water in the area is typically cold, as the pools are fed by mountain streams. The pools look as though they were pulled from the imagination of J.R.R. Tolkien.

The Tour Isabelle double arch, also named the Tour Percée arch, is a double natural arch, located in Chartreuse Mountains, in the French Alps. Its span is 32 metres (105 ft), which makes it the biggest natural arch in the Alps.
It remained unknown for probably everybody, until its discovery in May 2005, when Pascal Sombardier, who was trekking to write his book Chartreuse inédite : Itinéraires insolites, dealing with lost places of the range, discovered it fortuitously. Its pictures illustrated the front cover of his book, published in 2006 : this double arch became then the symbol of the hidden treasures of the Chartreuse Mountains.
Located in a very remote area, with a difficult and dangerous access, very few guide books, even the most recent ones, mention its existence.

The Adršpach-Teplice Rocks comprise some of the most popular rock formations in the Czech Republic. A sandstone rock town with many bizarre formations up to 300ft high open to the public since the middle of 18th century.
The Adršpach-Teplice Rocks are an unusual set of sandstone formations covering 17 km2 in northeastern Bohemia. The rocks have been protected as a national nature reserve since 1933, and since 1991 the whole adjacent region of Broumovsko has enjoyed the status of protected landscape area. Tourists may visit the rocks via a number of marked trails. The area is a popular destination for rock climbers.

Lake Powell is a man-made reservoir on the Colorado River in Utah and Arizona, United States. The Lake was created by the flooding of Glen Canyon by the Glen Canyon Dam, which also led to the 1972 creation of Glen Canyon National Recreation Area, a popular summer destination of public land. The lake also stretches up the Escalante River and San Juan River where they merge into the main Colorado River. This provides access to many natural geographic points of interest such as the Rainbow Bridge, the Hite Crossing Bridge, Cathedral in the Desert and San Juan goosenecks. The sparkling blue waters of Lake Powell are magnificently framed by towering rock formations and soaring red cliffs which surround the area for as far as the eye can see.

“That Wanaka Tree” – a willow growing just inside the lake – is a tourist attraction in its own right, featuring on many tourists’ Instagram feeds. The tree had its lower branches, including one branch that dips into the water, cut by vandals in 2020. The lone tree is at the foothills of Mount Aspiring National Park, New Zealand, a World Heritage Site and symbolises hope and endurance.
