Singapore's expensive reputation is half true, and the half that is true is hotels, alcohol and the big theme parks — not the sightseeing. The city's most famous attraction is largely free: the outdoor gardens at Gardens by the Bay, Supertree Grove included, are open from 5:00am to 2:00am at no charge, and the light show is free nightly. Add a free botanic garden, free ridge walks and hawker meals under five dollars and several days cost almost nothing in admission. Prices are in Singapore dollars as published.

1. Gardens by the Bay

The rare headline attraction where the iconic part costs nothing. The outdoor gardens are free and open 5:00am to 2:00am daily, and Garden Rhapsody, the light show at Supertree Grove, runs free every night at 7:45pm and 8:45pm.

The paid domes are optional. Cloud Forest is $26 for an adult, Flower Dome $12, the two together $46, and the Supertree Observatory $14. All are open 9:00am to 9:00pm. Worth knowing: single-attraction tickets cost the same for residents and visitors, so there is no tourist premium to dodge — the resident discount only applies to the combinations.

If you buy one thing, make it Cloud Forest at $26 rather than the $46 pair. Arrive around 6:30pm, do the dome, then be at Supertree Grove for the free 7:45pm show. Each paid attraction closes one day a month for maintenance, so check the date before you go.

2. The hawker centres

Not filler — this is the single biggest lever on a Singapore budget. Hawker centres are where a developed-world city still sells a proper meal for a few dollars, and entry is free; you pay only for food. Maxwell Food Centre in Chinatown, at 1 Kadayanallur Street by Tanjong Pagar MRT, is the most approachable for a first visit and trades 8:00am to 2:00am, though individual stalls keep their own hours and many shut by mid-afternoon.

For a sense of scale, the government's own survey of commonly sold hawker dishes put 2023 averages at $3.65 for mee siam, $3.82 for economical rice and $1.22 for coffee or tea without milk. Eating here rather than in malls is the difference between an affordable trip and an expensive one.

One practical warning: every hawker centre closes quarterly for cleaning and the dates are published in advance. Check before crossing town for a meal.

3. The Southern Ridges

A free ridge-top walk on elevated boardwalks linking a chain of parks above the harbour — the best free half-day in the city that is not Gardens by the Bay. Mount Faber Park and Telok Blangah Hill Park are open 24 hours and free, and HortPark runs 6:00am to 11:00pm.

Walk it finishing at Mount Faber above HarbourFront so you end next to an MRT station rather than stranded, and go late afternoon for the cooler light. Some current closures matter: sections of the Forest Walk are unlit between 7:00pm and 7:00am while maintenance runs to 30 September 2026, and part of the Mount Faber Loop footpath has been closed since January 2025, so you may be diverted between Henderson Waves and the cable car station.

4. Singapore Botanic Gardens

A UNESCO-listed garden that is free to everyone, every day, open 5:00am to midnight. The one paid section is among the cheapest world-class attractions in the city.

The National Orchid Garden is $15 for a non-resident adult, $3 for seniors over 60 and students, and free for every child under 12 regardless of nationality. It opens 8:30am to 7:00pm, but the last ticket is sold at 6:00pm — a full hour before closing, which locks out plenty of late arrivals.

5. MacRitchie Reservoir and the TreeTop Walk

A suspension bridge through rainforest canopy twenty minutes from the business district, with macaques and monitor lizards on the trail, and no admission charge. The reserve is open 7:00am to 7:00pm daily.

The hours are the strictest of anything here and getting them wrong wastes a morning: the TreeTop Walk is closed on Mondays except public holidays, runs 9:00am to 5:00pm on weekdays and 8:30am to 5:00pm at weekends, and last entry is 4:45pm. Start from the Venus Drive car park rather than the main entrance — it is a far shorter approach — and note the bridge is one-directional, so plan the loop before you set off.

Worth knowing

The short version

Singapore is not the expensive city it is sold as. The Supertrees, both light shows, the Botanic Gardens and the ridge walks are free, and hawker centres keep meals under five dollars. Buy one ticket — Cloud Forest at $26 — and let the free city carry the rest of the trip.
