1. Take a heritage tour
A British colony for nearly 150 years, from 1819 until 1963, Singapore boasts many beautifully maintained Victorian-era buildings along the Singapore River, just west of Marina Bay.
A walk through the central area will take travelers on a heritage trail, from the grand City Hall and Old Supreme Court, the Peranakan Museum, Fort Canning Flagstaff, St. Andrew's Cathedral, Victoria Theater and Concert Hall and The Arts House.
Many of the heritage buildings hug the Padang, an open playing field home to both the Singapore Cricket Club (est. 1870) and the Singapore Recreation Club (est. 1883)
Overlooking the cricket field, the recently renovated National Gallery Singapore specializes in Southeast Asian art.
It is a popular stop thanks to its ever-changing interactive exhibits, including a recent show by Japanese artist Yayoi Kusama, who harnessed infinity mirrors, patterns and light to create a compelling visual experience.

2. Eat everything
Singapore is said to be one of the world's best food cities - and it's easy to see why.
The island is home to the world's cheapest Michelin-starred meal - Hong Kong Soya Sauce Chicken Rice & Noodle - a humble hawker stall that sells its famous chicken and rice dish for just S$2 ($1.42)
This is just one of thousands of hawker stalls where travelers can indulge in tasty noodle dishes and quick snacks for just a few dollars.
The options are endless and all delicious, from the flaky roti prata in Little India to grilled satay, kaya toast (a coconut-like jam served with half-boiled egg), Hokkien mee noodles, laksa, Hainan chicken rice, chili crab and ice kachang - a dessert made with shaved ice, condensed milk and assorted toppings such as red beans and mango.
When thirst strikes, a cup of traditional kopi-o (thick black coffee with sugar), kopi kosong (without sugar), grass jelly soy milk or sugarcane juice should be easy enough to find.
Nearby, Maxwell Road Hawker Centre also draws crowds to its famous stalls, including the Tian Tian Hainanese Chicken Rice stall and Hoe Kee Porridge.
And for a contemporary take on the traditional hawker center? Try Timbre - an artsy outdoor gastropark with more than 30 food stalls, food trucks, craft beer vendors and live music nearly every night of the week.

3. Drink up the nightlife
Singapore might be known for its Singapore Slings - best savored at the famous Long Bar inside the 19th century Raffles Hotel - but that's not the only tipple worth a try.
The city is home to countless cocktail bars, particularly around Clarke Quay, Club Street, China Town and the Ann Siang Hill area.
Speakeasy 28 Hongkong Street serves up American-style classic cocktails and barrel-aged favorites, while Bitters & Love specializes in Asian-inspired cocktails with quirky presentations (like a Kaya Toast cocktail served in a mason jar).
Nearby, Operation Dagger does experimental libations in a sculptural setting.
For more low-key options, we'd suggest grabbing a seat outdoors at one of the hookah bars and alfresco cafes along Haji Lane.

4. Soak up some culture
Singapore is a melting pot of cultures with a diverse population, its residents hailing from Malaysia, China, India and more.
In Chinatown, the skyscrapers of Marina Bay fade into the background and three-story shophouses transport travelers back in time.
These quiet lanes, busy markets and traditional restaurants showcase Singapore's unique heritage.
Look closely and you'll notice that many of the traditional buildings have been remodeled into upscale boutique hotels, restaurants and speakeasies.
One example is ultra-slick Potato Head. Stretched across three floors in a heritage shophouse, it's now home to an intimate cocktail bar and rooftop restaurant.
While wandering around Chinatown, travelers will likely stumble upon Thian Hock Keng Temple, which is the oldest of its kind in Singapore, as well as the Buddha Tooth Relic Temple, and the Sri Mariamman Temple - a pastel-painted Hindu temple that perfectly embodies the city's multicultural identity.
Likewise, in Little India - toward the north side of the city - color and energy ooze out of sari tailor shops, gold jewelry boutiques and small restaurants.
For a bite, Lagnaa...barefoot dining - which is pretty much what it sounds like - comes highly recommended for its cushioned seating and tasty Indian cuisine.

5. Visit Marina Bay
Hugged by futuristic skyscrapers on all sides, Marina Bay is where you'll find Singapore's collection of modern architecture.
The centerpiece is, of course, Marina Bay Sands - a 55-floor hotel and entertainment mecca with an infinity pool, lookout point, and Ce La Vi bar and restaurant on the rooftop.
Inside, it feels awkwardly like an airport, but there's no arguing with its iconic status.
And for Formula One fans? A room here provides amazing views of the Marina Bay Street Circuit, where the Formula 1 SingTel Singapore Grand Prix takes place every September.
Elsewhere around the Marina, you'll find a few of the city's top landmarks, including the ArtScience Museum - shaped like blooming flower - the Merlion (fashioned after a mythical creature with a fish body and lion's head), the Singapore Flyer and No SignBoard Seafood Restaurant - famous for its addictive chili crab.

No SignBoard Seafood Restaurant, 8 Raffles Ave, 01-14/16, Singapore 039802; +65 6336 9959
6. Explore Gardens by the Bay
Directly behind Marina Bay Sands, an elevated walkway leads to the award-winning Gardens by the Bay.
This 101-hectare wonderland provides a futuristic ecosystem full of aerial walkways above the canopies, lakes, sculpture parks and 164-foot-tall Supertrees - vertical gardens that harvest solar energy.
Within the park, there are two climate-controlled conservatories - one a misty cloud forest and the other a Flower Dome.
The largest of its kind in the world, the 1.2-hectare glass greenhouse cultivates an incredible array of flora, olive trees and enormous African Baobab trees.
If that's not enough flora and fauna for you, we'd also recommend visiting the Singapore Botanic Gardens to the west.
Founded in 1859, the UNESCO World Heritage site is home to all kinds of walking trails, raw rainforest, sweeping green lawns and an immaculately manicured Orchid Garden with more than 1,000 orchid species.

7. Go on a safari
Safaris...in Singapore? The urban powerhouse doesn't seem like the most likely place to find monkeys and manatees - but you'd be surprised.
There are more than 6,000 beasts within the grounds of the River Safari - a river-themed experience northwest of the city center that traverses various ecosystems, from the River Nile to the Amazon.
The highlights include flamingos, one-horned rhinoceroses, wildebeests, monkeys, pufferfish, red pandas, crocodiles and more.
Tigers and bears more your thing? The next-door Night Safari delivers a tram ride through the rainforest, where tigers, leopards and elephants await.
It's all part of the larger Wildlife Reserves Singapore, including the Singapore Zoo, bird park, aquarium and a major research and conservation center.
Northwest of the complex, there's another worthy nature outing - the Sungei Buloh Wetland Reserve, an ASEAN Heritage Park.
This sprawling ecological jewel promises excellent hiking and birdwatching - with more than 140 bird species - along the mangrove boardwalks and wetland terrain.

8. Take a side trip
Most people think of Singapore as a cosmopolitan city, but there are actually 62 islands off its coast.
For a family-friendly side trip, Sentosa Island provides an easy option.
Located on Singapore's southern shore, the man-made island is home to Universal Studios, as well as golf courses and a few luxury resorts, such as the Capella Singapore or the glamorous W Sentosa.
For a more rustic adventure, we'd recommend Pulau Ubin or the Sisters' Islands - perfect for scuba diving, snorkeling, hiking and lounging around on clean beaches.
Departing from Changi Point Ferry Terminal, Pulau Ubin is about a 15-minute ferry ride away, with camping grounds should you wish to stay overnight - though travelers must register with the Pulau Ubin Police Post when they arrive.
Meanwhile, Sisters' Islands Marine Park comprises several islands, beaches and excellent snorkeling among the protected reefs.
To reach the islands, it's best to book a guided walk, which includes transportation as well as an introductory overview of the coral and wildlife preservation programs.
Otherwise, travelers will need to charter their own transportation from Marina South Pier.
