The Gardens by the Bay (GBTB) is an urban park spanning 105 hectares (260 acres) in the Central Region of Singapore, adjacent to the Marina Reservoir.

It stands at 15 hectares (37 acres) with a 3-kilometre (1.9 mi) waterfront promenade that allows for scenic walks stretching from the city centre to the east of Singapore.

[6] Bay East Garden is 32 hectares (79 acres) in size and has a 2-kilometre (1.2 mi) promenade frontage bordering the Marina Reservoir.

[10] The overall concept of its master plan by Grant Associates draws inspiration from an orchid as it is representative of the tropics and of Singapore, being the country's national flower, the Vanda 'Miss Joaquim'.

The conservatories, designed by WilkinsonEyre and Grant Associates, are intended to be an energy-efficient showcase of sustainable building technologies and to provide an all-weather edutainment space within the Gardens.

[11] The construction of glasshouses is special: having such a large glass roof without additional interior support (such as columns) and aiming to minimize the environmental footprint.

The Flower Dome also features several sculptures, such as a collection of 40 different driftwood animals by James Doran-Webb, Bruno Catalano's La Famille De Voyageurs, and Yayoi Kusama's Kei-Chan.

After ascending to the top by an elevator, visitors descend the mountain via a circular path which crosses underneath the 35-metre (115 ft) waterfall multiple times.

The "Cloud Mountain" itself is an intricate structure entirely clad in epiphytes such as orchids, ferns, spikemosses and clubmosses, bromeliads and anthuriums.

The following is a partial list of plants growing in the Cloud Forest:[16] In April 2022, a Māori kūwaha (meeting house) sculpture was presented to Singapore by Prime Minister Jacinda Ardern, of New Zealand, during her first official trip abroad since the 2020 pandemic.

[19] The Supertrees are home to enclaves of unique and exotic ferns, vines, orchids and also a vast collection of bromeliads such as Neoregelia and Tillandsia, amongst other plants.

There is an elevated walkway, the OCBC Skyway, between two larger Supertrees for visitors to enjoy a panoramic view of the Gardens.

The Observatory Space is located one level below the rooftop deck, and it consists of an indoor area with full-height glass windows and a peripheral outdoor walkway.

[20] Italy's Pavilion in Expo 2015, featured a structure called Albero Della Vita (or "Tree of Life" in Italian), which proved visually similar to Singapore's Supertrees.

[21] There are two distinctly different sets of horticultural-themed gardens, which centre on the horticultural heritage of the various cultural groups in Singapore and on the biology and ecology of the tropical rainforest.

The project received 1.7 million visitors between June and October 2012, who had free admission to most portions of the park but were required to purchase tickets for entering the Conservatories.

[41] Gardens by the Bay hosts several events throughout the year, predominantly the lantern-themed Mid-Autumn Festival, Christmas Wonderland, and River Hongbao (since 2021).
