Supertree Grove and Observatory Space, Singapore (must see)

Supertrees are a set of 18 tree-like structures that dominate the landscape of the Gardens. They vary in height from 25 meters (82 feet) to 50 meters (160 feet). These structures essentially function as vertical gardens, serving multiple purposes, including planting, providing shade, and acting as environmental tools for the gardens.

Within the Supertrees, you'll find clusters of unique and exotic plant species like ferns, vines, orchids, and a wide assortment of bromeliads, such as Tillandsia. They incorporate environmental technologies designed to mimic the ecological roles of natural trees. For instance, they have photovoltaic cells that capture solar energy, much like how trees photosynthesize, and they collect rainwater for use in irrigation and fountain displays, similar to how trees absorb rainwater for growth. Additionally, the Supertrees contribute to the cooling systems of the conservatories by serving as air intake and exhaust components.

Visitors can enjoy an elevated walkway called the OCBC Skyway, which connects two of the larger Supertrees and offers a panoramic aerial view of the Gardens. Every evening at 7:45pm and 8:45pm, the Supertree Grove hosts a coordinated light and music show known as the Garden Rhapsody. The music for the show changes monthly, featuring themes like "A World of Wonder" and "A Night of Musical Theatre," which include excerpts from movies such as Jurassic Park and Pirates of the Caribbean.

There's also a relatively new attraction known as the Supertree Observatory, which opened on December 27, 2019. It is housed within the tallest Supertree, standing at 50 meters tall, and consists of three levels: the ground floor, the Observatory Space, and the Open-Air Rooftop Deck. Visitors can take an elevator to the Observatory Space and then climb a flight of stairs to reach the Rooftop Deck. The Observatory Space features an indoor area with floor-to-ceiling glass windows and an outdoor walkway around the perimeter. Here, visitors can experience a message about the impacts of climate change conveyed through digital media. The Open-Air Rooftop Deck, situated atop this Supertree canopy, provides unobstructed 360-degree views of the Gardens and the Marina Bay area.
