Contrary to Longmen Cave, Guanyan is one of the best-equipped cave in Guilin. The cave contains 3 floors. The first floor is an underground river that's accessible only by boat, followed by an elevator that goes through a waterfall and leads to the second and the third floor. And then, a single-seat railcar will take you out of the cave and continue a little odyssey for 3 kilometres, and you can see the breath-taking landscape alongside the river coming towards you.

It is an engineering marvel, the world's steepest steam-operated railway. This is Tasmania's West Coast Wilderness Railway, and it is 28 tonnes of special. Today, passengers are moved by the same locomotives that began the run from Queenstown back in 1896. They take a comfortable 16-kilometre run through the wildlands, uphill through spectacular landscapes and down to a place called Dubbill Barrill, with stops for a little gold panning and sightseeing. These locos were originally built to move copper ore for the Mount Lyell Mining and Railway Company, delivering the mine's deep riches out of a massive, landlocked deposit at Queenstown to the port of Strahan, and from there, to the world. And every passenger is greeted by one of the line's original workhorses, a 28-tonne steam locomotive that's ready to roll — and guaranteed to raise a smile.
