Singapore’s Underground Shopping Links: A Hidden City Below the Heat

Getting your Trinity Audio player ready...

It can get pretty hot and humid in Singapore. Singapore’s heat hit me harder than I expected, and I wondered how long I could last outside. Then we stepped into a tunnel near Gardens by the Bay, and everything shifted. The walkway opened into cool corridors with small shops, places to sit, and a quiet break from the glare. I realized the city gives you another way to move—one that protects your energy and makes the day feel more manageable. Most guides tell you where to go. This part shows you how to move through the city without wearing yourself out.

Origins of the Underground Links

These routes began when Singapore needed more room. The city grew upward and outward. Planners looked below the surface because land stayed tight. Early walkways connected offices and malls. Later links reached MRT stations. Today, much of the network falls under the city’s Underground Pedestrian Links, or UPLs. The idea worked. Movement stayed steady during storms and heat. The tunnels became part of daily life.

The full system stretches more than eighteen miles. It connects more than seventy buildings. Some paths feel direct. Others turn between towers and stations. The reach surprised us. We crossed districts without stepping outside. The scale made the crowded center easier to navigate.

Key Routes, Old and New

Funan sits near City Hall and offers one of the newest UPL connections. The passage runs about one hundred meters, or roughly one-sixteenth of a mile. The air stays cool. The corridor feels wide. The shift from tunnel to mall feels smooth. This link shows how new projects shape the city beneath the surface.

CityLink Mall forms one of the oldest and busiest UPL areas. It connects City Hall, Esplanade, Suntec City, and Marina Square. Marina Bay holds another broad network. Walkways link office towers, hotels, and transit stations. These routes shorten long crossings. They help people move through dense districts with ease.

Comfort, Weather Protection, and Design

These passages protect people from direct sun also shielding travelers from sudden rain. They reduce long waits at wide intersections. They offer steady comfort during the hottest hours. We walked without squinting. We breathed without heavy air pressing into our chests. The design turned harsh weather into something we barely noticed.

Technology Behind the Tunnels

UPLs rely on cooling systems because air does not move on its own underground. Engineers use chilled-water cooling to manage heat. Cold water moves through pipes behind the walls. It absorbs warmth and sends cooled air back into the corridors. The temperature stays around twenty-four to twenty-six degrees Celsius, or seventy-five to seventy-nine degrees Fahrenheit. Sensors track heat and humidity. Pumps prevent flooding during storms. Drainage channels move water away from walkways. The systems run quietly, even when crowds fill the space.

Tips for Exploring

Start from any central MRT station. Follow basement signs. Keep track of levels because some links sit on B1 and others on B2. Walk early or late because midday crowds form fast. Look for narrow turns because many paths hide behind shops. Bring water since the routes stretch farther than expected. Many hotels connect directly to these underground walkways, so check if yours offers easy access for a seamless start. Check out our hotel, Village Albert Court Hotel, for convenient access and a great location near key attractions.
