Just an hour's boat trip away from Cartagena lie the magnificent Rosario Islands, which belong to Colombia's only underwater natural park (Rosario and San Bernardo Corals National Natural Park). Abundant marine wildlife (including over 50 species of corals) and some of Colombia's best beaches draw in many in search of relaxation and active pursuits such as snorkelling and diving. Isla Grande is best for kayaking through unique mangrove forests and seeing the phosphorescent plankton light up the waters of a brackish lake at night, while Playa Blanca is Cartagena's most spectacular white-sand beach (also reachable by land). It should be said that the company you choose to tour with has the potential to make or break the experience. Low cost tours can mean multiple intermediate stops en route to your destination, as well as unpleasant surprises such as no transfer back to your hotel. Try and choose a trusted company with consistently good reviews, or opt for a private tour. Mind that seas may be rough at certain times of the year, particularly in December and January, when tours on smaller boats may even become dangerous.

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.
