The Cloud Mountain is entirely man-made, constructed over a reinforced concrete core to support the weight of thousands of live plants.
The waterfall is one of the world's tallest indoor cascades, standing at 35 meters.
The conservatory's glass envelope is designed to minimize heat gain while maximizing light transmission for photosynthesis.
The Secret Garden area focuses on limestone forest flora, which are naturally rare and often overlooked.
The facility functions as a research repository for rare plant species threatened by climate change in their natural habitats.
Cloud Forest is a key component of the Gardens by the Bay's sustainability efforts, utilizing energy-efficient cooling and water harvesting systems.
The Cloud Forest is a climate-controlled conservatory within Gardens by the Bay, Singapore, designed to replicate the cool-moist conditions of tropical montane regions between 1,000 and 3,000 meters above sea level. Its central feature is a 35-meter-tall man-made mountain cloaked in epiphytes, ferns, and orchids, featuring an internal waterfall that cascades from the summit. Visitors ascend to the top via elevator and descend through elevated aerial walkways, including the Cloud Walk and Treetop Walk. The facility houses a Lost World zone at the peak and a subterranean Cavern filled with stalactites and stalagmites. The structure utilizes a glass-and-steel lattice dome with a sophisticated cooling system to maintain temperatures between 23°C and 25°C. As of June 2026, it remains a flagship attraction within the larger Marina Bay reclaimed land development. The garden exhibits diverse flora, including carnivorous plants, begonias, and rare orchids sourced from high-altitude environments.
The mid-point of the Cloud Walk, providing a direct eye-level view of the mountain's waterfall and the distant city skyline through the glass.
Carry a light jacket as the indoor temperature is kept significantly cooler than the outdoor tropical heat.
Visit the Cloud Walk early in your tour to avoid congestion during peak mid-day periods.
Use the internal elevator to bypass the steep climb and go straight to the Treetop Walk levels.
Do not rush through the lower levels; many visitors overlook the Crystal Mountain and Cavern exhibits at the bottom.
Occasionally closed for maintenance; check the official website for monthly closure dates before visiting.
Maintain a quiet volume; do not touch or remove plant life; photography is permitted but avoid using tripods in narrow walkways.
