For many Singapore may bring to mind skyscrapers with financial corporation headquarters, high-tech industry and one of the largest harbours in the world. And this is true, but Singapore is no concrete jungle — on the contrary it was the vision of founding prime minister Lee Kuan Yew, that it should not be so. The Government often refers to Singapore as "City in a Garden" and that is largely true; there are plants and trees everywhere, even in the CBD, and apart from the many great parks there are also a number of wild, green patches. One patch, the Bukit Timah Nature Reserve consists almost exclusively of primary rainforest, and is said to have more species living there than North America, and although that is debatable the biodiversity is indeed extremely high. Singapore has tropical rainforest within its city limits, and the Singapore Botanical Garden is one of only three botanical gardens to have UNESCO World heritage status (The other two being Kew Gardens in London and Padoa Botanical Garden in northern Italy). In Singapore you can board a train or bus and go directly to primary rainforest or mangrove swamp, and at the same time you don't really have to worry about horrid tropical diseases, poisonous snakes (do exist, but are quite rare) or giant spiders.

Singapore is part of the Indomalayan Realm, with South Asian wildlife.

Prepare

Symphony Lake, Singapore Botanic Gardens

Singapore is generally an extremely safe place to be and very easy to navigate, and you can buy almost anything after arriving. But being placed in the "high tropics" just a few degrees north of equator you will need to deal with both heat (always) and strong sun (when the sky is clear, more rarely). Be sure to check the weather forecast particularly if you plan to visit in the afternoon or early evening where there is a higher probability of rain. Wherever you go into nature bring water. A cap is a good idea, as well as sunblock and covering but very light clothing. When going into nature you will need to balance between the long pants and sturdy shoes required by location, and the shorts and sandals required by the climate.

Also note that Singapore has (and enforces) very strict regulations on collecting plants and especially animals, and even on straying from the official paths - and this is good for there are a lot of people sharing the nature!

All publicly accessible nature comes well signed, and it pays off to read the information given as it will tell in those few cases where caution is needed!

For a high-tech country like Singapore, it is in some cases amazingly dependent on cash; when going into nature you will find soft drink vending machines in the most unlikely places (to avoid people dehydrating) but they usually accept only coins (≤$1) and small notes (~$2).

Changi airport

While not really a sight in itself, Changi airport is the point of entry for most visitors and deserves mention for the impressive greenery displays found everywhere in the airport - worth mentioning is a large stand of Agathis at immigration (one side). Jewel Changi Airport is a mixed-use development at Changi Airport in Singapore that opened in 2019. It includes gardens, a hotel, aviation facilities and 300 retail and dining facilities
