Singapore looks expensive until you walk past the malls. The hawker centres serve S$4 plates, half the best gardens and trails charge nothing, and an EZ-Link card moves you across the island for pocket change. Three days, roughly S$40 a day.
Free daily 05:00–midnight, and a UNESCO World Heritage Site since 2015. The 6-hectare Rain Forest tract predates the 1859 garden itself. Skip the paid National Orchid Garden (S$15) and walk Swan Lake, the Ginger Garden and the Bandstand instead.
Second floor of a 1950s market in Singapore's first public housing estate. Jian Bo Shui Kueh sells steamed rice cakes at S$2.50 for five, Tiong Bahru Hainanese Boneless Chicken Rice runs S$5. Most stalls close by 14:00 and the whole place shuts Mondays.
A free hilltop park layered with Raffles' 1822 experimental spice garden, a 14th-century Malay royal site, and the WWII Battlebox bunker above ground. The Fort Canning Tree Tunnel — a spiral stairwell framed by tembusu canopy — costs nothing to photograph.
Singapore's oldest Hindu temple, founded 1827, with a gopuram stacked with painted deities. Entry is free; a S$3 camera fee applies if you shoot inside. Open 07:00–12:00 and 18:00–21:00, so the evening slot catches the puja and the lit tower.
Ground-floor hawker stalls plus a wet market of goat carcasses and banana-leaf vendors upstairs. Allauddin's Briyani plates mutton biryani for around S$7; teh tarik is S$1.60. Busiest and cheapest on Sunday when migrant workers fill Buffalo Road.
Free to wander: the gold-domed Sultan Mosque of 1928 (open to visitors 10:00–12:00 and 14:00–16:00, robes provided), then the two-metre-wide Haji Lane lined with murals and shophouses. Arab Street's textile shops still sell by the metre.
Built on the runway of the 1937 Kallang Airport and rated by locals above any tourist hawker centre. Lao Fu Zi fried kway teow is S$5, Toa Payoh Rojak S$5, Roast Paradise char siew S$6. Over 150 stalls; many sell out by mid-afternoon.
A free public dam roof with an unobstructed line on the Marina Bay skyline, open 24 hours with no ticket and no queue. Locals bring kites and picnics; the sea breeze across the reservoir is the only reliable air-conditioning outdoors in Singapore.
Free entry to 163 metres — Singapore's highest natural point — through primary rainforest with long-tailed macaques on the handrails. The paved summit route takes about 40 minutes up. Open 07:00–19:00; go early, the humidity is brutal by 11:00.
Singapore's highest pedestrian bridge at 36 metres, a wave of curved yellow balau slats between Mount Faber and Telok Blangah Hill. Free, open around the clock, lit by LEDs after 19:00. The full Southern Ridges walk runs 10 km if you keep going.
A ten-minute bumboat from Changi Point Ferry Terminal costs S$4 each way and lands on an island still living as 1960s kampong Singapore. Bicycle rental at Ubin village runs S$8–15 a day; Chek Jawa's wetlands boardwalk is free.
A 2.2 km wooden boardwalk hugging the cliff back to Changi Village, where stall #01-57 has queued for nasi lemak since the 1980s at about S$4.50 a plate. Planes on the Changi approach pass directly overhead every few minutes.
