Zoo, night safari and bird park
Night Safari
A part of the Zoo but located on completely separate grounds that are closed during the day, this is the world's first wildlife park built to be viewed at night. The grounds are in fact larger than the main Zoo and only parts are accessible to visitors on foot, so most people opt for the guided tram tour instead. There is a 30 minute show at the amphitheater with trained animal displays three times per night. Sit in the center section three rows from the front for a nice surprise. The tram tour is highly recommended unless you have the time to do a lot of walking and it brings you the eastern part of the park which is not accessible by walking. Lighting throughout the park is minimal, but sufficient. Stopping at the second tram station is a must as there is a walking path The Leopard Trail for viewing giraffes, flying squirrels, lions and others. Flash photography is not allowed, so a tripod is recommended. Some other animals you can expect to see include various types of tigers, elephants, bats, flamingos, porcupines, leopards, otters, badgers, and storks.
Singapore Zoo
One of the best zoos in Asia, if not the world — it was endorsed by the late Steve Irwin and Animal Planet uses it for some of its documentaries. The animals are kept in spacious, landscaped enclosures, separated from the visitors by dry or wet moats. To spare yourself walking under the hot tropical sun, you can board a little train that trundles through the park, but it's still best to get there early. Bring along swimsuits for kids, so they can cool off in the "Kidz Zone". There's also a Jungle Breakfast $25/16 adult/child extra, daily at 9 AM, where you're joined at a buffet breakfast by a host of critters from orangutans to otters and you can even try feeding the elephants; very popular, so book ahead.
Jurong BirdPark
A 20.2 hectare open-concept park dedicated to, you guessed it, birds in all shapes and sizes. The Park specializes in birds from Southeast Asia and the more exotic and colorful tropical birds, and its collection of more than 8,000 birds from 600 species is among the largest in the world. The park is attractively presented and quite enjoyable even if you aren't a hardcore ornithologist. To ease the pain of slogging around in the tropical heat, you can circle the park with the Panorail monorail. It features the tallest man made waterfall, at 30 meters.
Historical
Reflections at Bukit Chandu
Small but well-implemented commemorative museum for the last stand of the Malay Regiment in World War II's Battle of Bukit Chandu. Nearest bus stop Pasir Panjang Community Centre lines 10, 30 from central Singapore, but it's still a bit of a hike up the hill from here. If visiting here, make a short detour to the free Canopy Walk next door a part of the Southern Ridges Walk, an elevated footpath through the jungle offering nice views of Singapore's heartlands.
Memories at Old Ford Factory
War museum at the old Ford Motor Factory, where British Lt-General Percival surrendered Singapore to the Japanese. Focuses on the subsequent Japanese occupation and the experiences of both civilians and POWs with modern presentation and multimedia gadgetry, but if you're pressed for time, the Changi Chapel covers much the same territory and is probably the more interesting of the two.
Labrador Park and Labrador Secret Tunnels
Opened in May 2005, there are two ways of looking at these two restored British-era bunkers: either they're done a pretty good job of making a tunnel interesting, or even if you dress it up with spot lights and recorded booms, it's still just a bunch of tunnels. There are also some machine gun posts, old artillery guns etc scattered about in Labrador Park, which also has some walking trails and quiet stretch of seashore opposite Sentosa.
Gardens
Chinese Garden and Japanese Garden
Free and nice for a walk and/or picnic. Also check out the tortoise and turtle sanctuary in the Chinese Garden. $5 adult admission and $2 for leafy vegetables and food pellets let you get up close and personal with these wonderful creatures. Worth a visit during the Mid-Autumn Lantern Festival Sep-Oct, exact date varies, when the garden is lit up with tens of thousands of lanterns, including complex installations with moving figures based on themes ranging from Hello Kitty to Chinese folk tales.
Botanic Gardens
Once considered among the finest botanical gardens in the British empire, and still a firm favorite for visitors and locals alike. Features trees and plants from tropical climates around the world. Walking and jogging trails are throughout. Outdoor sculptures dot the gardens. Look for the girl on the swing that appears to hang from an invisible chain in the air. Picnicking is allowed, but there are also quite a few cafes and restaurants see Eat.
Other
Haw Par Villa
Formerly the Tiger Balm Gardens, this is the former site of the villa of the Tiger Balm brothers, Aw Boon Haw and Aw Boon Par, now packed with an incredibly bizarre assortment of statues illustrating Chinese legends and moral values. The most famous bit is the Ten Courts of Hell, which demonstrate in gruesome detail how sinners get punished in the underworld: for example, ingratitude is punished by grilling on a red hot copper pillar, while cheating in exams merits having your body dismembered and your intestines pulled out.
Singapore Science Centre
Set up to promote interest and learning in science and tecnhology through assortment of exhibits. There are more than 850 exhibits in the various exhibition galleries firmly aimed at younger children 6-10 and it is not possible to view all exhibits in one visit. There is also an interesting water park area near the front entrance.
Kong Men San Phor Kark See Monastery
Singapore's largest Buddhist temple and monastery sprawls over a hill in a residential suburb of Singapore. Founded in 1920, the present buildings are all oversized and rather gaudy concrete structures, but it's still a rather surreal place. The highlight is the Pagoda of 10,000 Buddhas, whose dome is decorated on the inside with, you guessed it, ten thousand tiny Buddha figures. Runs meditation retreats mostly only in Chinese though and gets packed with worshippers on major Buddhist holidays.
