Sua Ocean Trench, Samoa
As well as the stunning gardens that form a perimeter around the hole, there is also a secluded beach on the western side of the land-formation and a number of little blow holes. A long ladder descends down into the pool so that you can access it safely, but be careful as this can become slippery with use. You will find this intriguing slice of perfection in the Lotofaga region of the island.
Salar de Uyuni salt flat, Bolivia
Little mounds of salt appear across the horizon, and occasionally you’ll see the odd structure made completely out of the mineral. One of these novel hotels will almost certainly be a part of any trip to the flats as well as an excursion to the eerie train graveyard; a collection of old, wrecked steam engines.
The contrast between the pure, white salt and the vivid blue sky is quite a sight in itself, but it’s the evening, when the stars come out, that the view is at its finest. Tours of the flats can last from one to four days, but it’s best to get an overnight stay in to make the most of it.
Pink Lake, Western Australia
Pink Lake, close to the small town of Esperance, is surrounded by white sand and a short distance away from the stunning Australian coastline. For the best views of this bizarre natural phenomenon, take the walk up to the Pink Lake look-out.
The Stone Forest, Madagascar
Standing as tall as 300 feet, these grey pinnacles are incredibly difficult to get to due to the harsh terrain surrounding them and their distance from civilisation. As a result of this, there is very little human presence in the area, which has allowed a number of different species to thrive. The most notable inhabitant of the Grand Tsingy – the official name for the area – is the lemur, which lives high up in the rocks.
The catacombs, Paris
The eerie corridors are actually part of the old stone mines that were used to source rock and build the city. Due to overflowing cemeteries in the 1500s, the long-dead were exhumed and placed in the mines which have today become a museum as well as a monument to the deceased. This is not one for the claustrophobic or the faint of heart.
