Night Safari

This is another of the great attractions of Singapore. Making the most of having one of the best zoos in the world and amazing plant life, as soon as it's night and until midnight there's a nocturnal safari, which at only 20 euros lets you have a unique experience. Hop on the train or walk down the middle of a jungle and be surrounded by free animals (though controlled, don't worry). It is certainly highly recommendable. Tucked away from the city, but in a taxi you can be there in half an hour and will cost less than 10 euros.
