Supertree Grove
(Supertree Observatory & OCBC Skyway)


Measuring between 25 and 50 metres tall, Gardens by the Bay's Supertrees are designed with large canopies that provide shade in the day and come alive with an exhilarating display of lights and sounds at night. Stand in awe amidst these iconic giants, stroll along the 22-metre-high OCBC Skyway and enjoy panoramic vistas of the Gardens and the Marina Bay skyline at our new Supertree Observatory.

Fascinating Facts About The Iconic Supertrees

Get to know the Supertrees from the inside out. In addition to providing scale and dimension to the landscape around the Gardens, the Supertrees were also designed to mirror the form and function of mature trees.

These unique trees can be found all around the Gardens – twelve at the Supertree Grove, while the remaining six are placed in clusters of threes at the Golden and Silver Gardens. Take in a different view of the Gardens and stroll along the OCBC Skyway, a 128-metre long walkway connecting two Supertrees at the Supertree Grove. Chill out at 50-metres high at the Supertree-top bistro and be captivated by the panoramic views of the Gardens as well as the surrounding Marina Bay area.


  • Each Supertree comprises four major parts:

    • Reinforcement concrete core – Inner vertical structure that upholds the Supertree.
    • Trunk – A steel frame that is attached around the reinforcement concrete core.
    • Planting panels – Installed on the trunk in preparation for the planting of the living skin.
    • Canopy – Shaped like an inverted umbrella, the canopy was assembled and hoisted via a hydraulic jack system (except the 50-metre Supertree canopy which was assembled at its final height).

Environmentally Sustainable Functions

    • 11 Supertrees have canopies embedded with environmentally sustainable functions.
    • Some will have photovoltaic cells to harvest solar energy for lighting up the Supertrees. Others are integrated with the Cooled Conservatories and serve as air exhaust receptacles.


  • How tall is a Supertree?
    About as tall as a 16-storey building.
  • How about the OCBC Skyway?
    The OCBC Skyway connects the Supertree Grove into a 128-metre long walkway at 22-metres high.


    • Over 158,000 plants comprising more than 700 species and varieties of bromeliads, orchids, ferns and tropical flowering climbers have been planted on the 18 Supertrees.
    • Examples of some of the species include the Tillandsia stricta from Brazil, Tillandsia fasciculate from Panama, Cattleya maxima from Ecuador, and Pseudorhipsalis from Costa Rica.
    • The Supertrees have different planting schemes in various colours ranging from warm tones like reds, browns, orange and yellows, to cooler hues like silver and pink.
    • The plants were chosen based on the following considerations:

    - Suitability for vertical planting
    - Lightweight and hardy
    - Soil-less
    - Ease of maintanence
    - Suitability for Singapore’s climate
    - Not commonly found in Singapore
    - High visual interest


  • Is a Supertree made of trees?
  • What is it made of?
    Each Supertree consists of a trunk core made of reinforced concrete wrapped with a steel frame. Planting panels are installed on the trunks for the planting of the living skin. Each canopy is embedded with environmentally sustainable functions, then assembled and hoisted via a hydraulic jack system.
