Gardens by the Bay in Singapore is a breathtaking 101-hectare waterfront garden built on reclaimed land beside Marina Bay. Since opening, it has become one of the most recognizable attractions in Asia, drawing millions of visitors every year with its futuristic skyline of glass conservatories and glowing “Singapore Supertrees.”
The master-planned attraction is made up of three main waterfront gardens – Bay South Garden, Bay East Garden, and Bay Central Garden. Bay South is the largest and most famous, home to the instantly recognizable Supertree Grove, the Flower Dome, and the Cloud Forest conservatories. Bay East provides quieter lawns and waterfront promenades with postcard views of Marina Bay, while Bay Central acts as a green link between the two.
What sets Gardens by the Bay apart from traditional botanical gardens is how it blends tropical horticulture, landscape design, and green engineering. Every major feature, from the cooled conservatories to the Supertrees, is designed to showcase cutting-edge sustainability – capturing rainwater, using solar power, and helping to cool the micro-climate around the gardens.
The most striking feature of the gardens is the collection of 18 Singapore Supertrees in Bay South. These towering vertical gardens range from about 25 to 50 meters in height and are arranged in clusters, with the main Supertree Grove forming the centerpiece. Each Supertree is a steel “trunk” wrapped in planting panels that support thousands of plants, including ferns, orchids, bromeliads, and tropical climbers.
Beyond their sculptural beauty, the Supertrees perform real environmental functions. Many are fitted with photovoltaic cells that harvest solar energy to help power the evening light shows. Others act as air exhaust receptacles for the cooled conservatories, venting hot air away from the glass domes. Their trunks and crowns also help to collect rainwater, which is routed into the garden’s water system and used for irrigation.
During the day, the Supertrees provide welcome shade from the equatorial sun and act as shady vertical parks. At night they transform into illuminated “trees of light” during the popular Garden Rhapsody show, where thousands of LEDs and spotlights are choreographed to music. From the ground, visitors look up into a glowing canopy; from the OCBC Skyway – a suspended walkway connecting two of the taller Supertrees – you can stroll 22 meters above ground with sweeping views of Marina Bay Sands and the Singapore skyline.
The Supertrees sit outside in the gardens, but they visually frame and support the experience of the two cooled conservatories nearby: the Cloud Forest and the Flower Dome. Many visitors start with the Supertree Grove at ground level and then move indoors to explore the contrasting climates recreated under glass.
The Cloud Forest Conservatory is a cool, mist-shrouded dome that recreates the rare environment of tropical cloud forests found at higher elevations in Southeast Asia, Central and South America, and Africa. At its heart stands a 35-meter-tall man-made “mountain” completely wrapped in lush vegetation, mosses, and epiphytes.
Entering the Cloud Forest, visitors are immediately greeted by the thunderous sound and cool spray of the world’s tallest indoor waterfall, cascading from the top of the mountain into a planted pool below. Elevated walkways and glass-walled ramps spiral around the mountain, taking you up through different “altitude zones,” each with its own plant communities and micro-climate.
Interpretive exhibits highlight the biodiversity of cloud forests and their vulnerability to climate change. You’ll see rare orchids, carnivorous pitcher plants, ferns, moss gardens, and other species that normally cling to steep, misty mountain slopes. Educational displays also explore how these forests store water and carbon, echoing the broader reforestation and conservation themes that sites like Tree Plantation champion.
From viewing platforms near the top of the mountain, you can look out across the conservatory glass and glimpse the Supertree Grove and Marina Bay skyline beyond – a visual reminder of how Gardens by the Bay stitches together urban architecture, glass biomes, and vertical forests into one continuous landscape.
Like the Supertrees, the Cloud Forest is also a showcase of sustainable design. The cooled conservatory uses high-performance glass, shading devices, and a sophisticated cooling system that chills only the lower occupied zones rather than the entire air volume. Part of the excess heat is exhausted through the nearby Supertrees. Rainwater collected from the conservatory roof is filtrated and reused for irrigation and waterfall circulation, creating a closed loop that keeps water and energy use in check.
Next to the Cloud Forest sits the Flower Dome, recognized as one of the largest column-free glass greenhouses in the world. While the Cloud Forest is cool and misty, the Flower Dome recreates the dry, mild climates of Mediterranean and semi-arid regions – think coastal California, parts of South Africa, Chile, and the lands around the Mediterranean Sea.
Visitors enter the Flower Dome through a bright lobby that opens into a wide, gently sloping space filled with themed gardens and sculpted beds. From almost anywhere inside you can see out toward the Supertree Grove, Marina Bay Sands, and the open water – reinforcing that you are in a modern city even as you walk among ancient olive trees and towering baobab look-alikes.
The dome is divided into a series of climate-inspired gardens. A Mediterranean Garden highlights aromatic shrubs and trees from southern Europe and the Middle East. The South African Garden showcases proteas, aloes, and other species from the Cape Floral Kingdom. Another zone focuses on Australian myrtles and flowering shrubs, while a South American section displays cacti and succulents that thrive in drier conditions.
Throughout the year, the Flower Dome hosts rotating floral displays that keep repeat visits interesting: Chinese New Year themes with chrysanthemums and peonies, the popular Tulipmania event with Dutch-style fields of tulips, and large-scale orchid exhibitions with thousands of blooms. Sculptures, whimsical art pieces, and seasonal installations are woven into the planting beds to create a gallery-like experience for visitors and photographers.
Just as with the Cloud Forest, the Flower Dome relies on efficient glazing, shading, and targeted cooling to maintain its mild interior climate while minimizing energy use in Singapore’s tropical heat. Both conservatories, together with the Supertrees and surrounding gardens, make Gardens by the Bay a global reference point for integrated landscape design and sustainable horticulture.
Beyond the headline attractions, Gardens by the Bay includes a network of landscaped lakes, outdoor gardens, and interpretive trails. The Dragonfly and Kingfisher Lakes are designed wetlands that help filter stormwater while providing habitat for fish, birds, and aquatic plants. Elevated boardwalks and viewing platforms explain how the lakes tie into Singapore’s broader efforts to manage water and create urban biodiversity corridors.
The nearby Heritage Gardens explore the role of plants in Singapore’s cultural tapestry – showcasing species important to the Chinese, Malay, Indian, and colonial European communities that helped shape the city. Culinary herbs, fruit trees, spices, and medicinal plants are displayed with signage that connects botany to food, medicine, and traditional crafts, echoing the broader theme of trees and plants as the foundation of human life.
Most visitors plan at least half a day at Gardens by the Bay, combining a walk through the Supertree Grove with visits to the Cloud Forest and Flower Dome. It’s wise to see the conservatories in the late morning or early afternoon when the tropical sun is strongest, then return to the Supertrees around sunset to catch the Garden Rhapsody light and sound show under the night sky.
Tickets can be purchased for the conservatories alone or bundled with access to the OCBC Skyway, the aerial bridge that runs between two Supertrees. Comfortable footwear, a camera, and a light jacket for the cooler Cloud Forest are all recommended. Dining options inside and around the gardens range from casual cafés to restaurants with panoramic views over Marina Bay.
The Singapore Supertrees at Gardens by the Bay are more than a photo backdrop – they are working prototypes for how vertical green infrastructure can shade cities, support biodiversity, and integrate renewable energy. Their success has inspired architects, urban planners, and horticulturists worldwide to explore new models of sky gardens, living facades, and elevated tree canopies.
For organizations focused on reforestation, tree plantations, and innovative propagation systems, Gardens by the Bay provides a useful case study in how public landscapes can educate visitors about climate change, conservation, and sustainable design. Technologies like vertical planting systems, efficient irrigation, and smart climate control share common ground with next-generation propagation and agroforestry concepts being developed for food forests and climate-resilient tree plantations.
Whether you are drawn by the engineering, the plants, or the views, the Singapore Supertrees and their surrounding biomes are a must-see. From the cool mists of the Cloud Forest and the seasonal displays of the Flower Dome to the glowing trunks and canopies of the Supertree Grove at night, Gardens by the Bay offers one of the world’s most compelling examples of how cities can weave nature, architecture, and technology into a single living landscape.
The Singapore Supertrees are towering, tree-shaped vertical gardens in the Gardens by the Bay complex. Each “tree” is a steel trunk and canopy wrapped with living plants—orchids, ferns, and bromeliads—that create a vertical forest in the heart of Marina Bay. They provide shade by day and transform into an illuminated grove at night during the Garden Rhapsody light-and-music show.
Several Supertrees are fitted with photovoltaic panels that harvest solar energy to power the nightly light displays and site lighting. Others act as exhaust and air-intake stacks that help passively cool the nearby Cloud Forest and Flower Dome conservatories. Together with extensive rainwater collection and irrigation systems, they demonstrate how green infrastructure can cut energy use and manage water in dense cities.
The Supertrees range from roughly 25 to 50 meters (about 80–160 feet) in height, with the tallest ones forming the core of the Supertree Grove. Visitors can purchase tickets to walk the OCBC Skyway , a suspended walkway that connects several canopies and offers sweeping views of Marina Bay Sands, the conservatories, and the Singapore skyline. In the evening, plan to stay for the free Garden Rhapsody show, where the Supertrees come alive with synchronized lights and music.
The trunks of the Supertrees are planted with a curated mix of epiphytes and climbers chosen for color, texture, and durability in a tropical urban climate. These include many species of orchids, ferns, bromeliads, and flowering vines similar to those you might see in high-elevation cloud forests and rainforest canopies. These plantings complement the collections inside the Cloud Forest and Flower Dome and create habitat for birds and insects in the city.
In land-scarce cities like Singapore, the Supertrees show how vertical gardens can stack ecological functions—shade, cooling, stormwater capture, and habitat—into a compact footprint. They complement traditional street trees and parks by adding green space vertically and by integrating with energy and water systems. As a flagship project in climate-smart urban design, the Supertree Grove has become a global case study in how architecture, ecology, and public art can work together to cool cities and reconnect people with plants.
You’ll get two very different experiences: day and night. Visit during the day to see the plant details up close, walk the OCBC Skyway , and explore the lakes and conservatories. Then return or stay through sunset to watch the Supertree canopies light up for the Garden Rhapsody show. If you’re planning a longer trip that includes other forests and tree destinations, you can pair Gardens by the Bay with more traditional urban forestry walks and nature reserves around Singapore.
