The Singapore Zoo's Night Safari is the most popular tourist attraction in Singapore, and an absolute must for family vacationers. The Night Safari is housed within 40 hectares of tropical rainforest, and was conceived of as a way to allow visitors to observe nocturnal animals 'acting naturally'. The method in which this has been achieved is typically ingenious: the zoo is closed during the day so the animals' sleep isn't disturbed, and at night it is lit by soft lighting that resembles natural moonlight. The zoo is divided into eight distinct 'geographical regions' - from the Himalayan Foothills to Equatorial Africa - which are accessible either by tram or on foot, and which display animals native to those regions, from tarsiers to tigers. The Night Safari houses over a thousand animals from 120 species, 29 percent of which are threatened species. Welcoming over a million visitors a year, the Night Safari is a deservedly popular Singapore tourist attraction - and a wonderful place to take the children, offering them the rare and exciting opportunity to feel as though they're 'peeking in' on a real animal kingdom.
