Located on the western coast of the island, the city of Colombo is the economic capital of Sri Lanka (the administrative capital being Sri Jayawardenapura Kotte). It is one of the country's main entry and exit points, making it an essential stop on any Sri Lanka itinerary. The good news? The city is brimming with historical, architectural and cultural treasures. Discover all the things to do and see in Colombo in one day. 

Morning: exploring the Fort Colombo and Pettah districts 

To start your day discovering Colombo, we suggest heading to the Fort Colombo and Pettah districts, two must-see neighborhoods where the majority of the city's attractions are located. 

The Fort Colombo district

The Fort Colombo district (or Fort) is the historic heart of the city. It's also Colombo's central business and financial district. Today it's home to the headquarters of numerous government institutions, such as the President's residence and several ministries.

Wandering through the paved alleyways of Fort Colombo, you'll be dazzled by the colonial architecture. For a bit of history, the city once housed a real fort built first by the Portuguese before being demolished and rebuilt by the Dutch during the conquest of the Dutch East India Company. Much of the fort was later destroyed under British rule, and many Dutch buildings were replaced by structures with neoclassical architecture. 

Today, only a few remnants of the fort and its ramparts remain (such as the Delft Gate, one of the 3 main entrances), and the district has become a charming labyrinth perfect for leisurely strolls. 

Among the must-sees in the Colombo district, we recommend: 

• The Clock Tower: the former Colombo lighthouse, known as the Old Lighthouse, now transformed into a clock tower; 

• The Dutch Hospital: dating from the Dutch colonial era, this former hospital is considered the oldest building in the district. Beautifully restored, it now houses a shopping and dining center; 

• The Sambodhi Chaithya: a Buddhist stupa and sanctuary built with reinforced concrete. Erected on a platform above Marine Drive at the entrance to the port, you can climb to its top to enjoy breathtaking views of Colombo's harbor; 

• The World Trade Center (WTC Colombo): the city's most important business center, consisting of 2 twin towers of 40 stories each and standing 152 m high. 

The Pettah district

Located right next to the Fort district, Pettah is one of the city's oldest neighborhoods. A true cultural and commercial melting pot bustling with activity, it's also one of the most popular and lively areas. 

Among the things not to miss in the district, we recommend: 

Pettah Market

The district is especially renowned for its sprawling open-air market, popular with both locals and tourists alike. It's Sri Lanka's most bustling commercial zone and the country's largest street market. Forming a labyrinth, you'll find absolutely everything: spices, food products, handicrafts, clothing and textiles, jewelry, high-tech items... Take the opportunity to stop at a street food stall to sample Sri Lankan culinary specialties

Jami-Ul-Alfar Mosque (or Red Mosque)

Another iconic Colombo site to discover in the Pettah district: the Jami-Ul-Alfar Mosque, one of the city's oldest (1908). Better known as the Red Mosque, it's characterized by a construction of red and white bricks forming stripes. It combines Indo-Islamic and indigenous Indian architectural elements with neogothic and neoclassical styles. You can visit the interior outside of prayer times.

Our tip: 

To save time, we highly recommend taking a tuk-tuk to move between Colombo's different districts (especially if you're traveling to Sri Lanka with family and children). This will help you avoid crowds and see as much as possible in minimal time. Plus, beyond being practical, this mode of transport always offers a quirky and fun experience!

Afternoon: exploring Beira Lake and Gangaramaya Temple

For the afternoon, we recommend heading to the Beira Lake district. It's a chance to take a break from the urban hustle and bustle before discovering the Gangaramaya Temple, located right nearby.

Beira Lake

A former moat with a turbulent past where crocodiles once thrived to deter enemy troops, Beira Lake is now the city's green lung. Many locals come to stroll along its banks, escaping the city's hustle. 

On Beira Lake, you can admire the Gangaramaya Sima Malaka. Set on the water's surface thanks to stilts, this floating temple is an extension of the Buddhist Gangarama temple. It once served as a place of entertainment and tea trading post for the British and is now used as a place of rest and meditation rather than worship.

Around the lake, you can also admire the Lotus Tower (also called Nelum Kuluna). Standing 350 m tall, it's the country's tallest skyscraper and South Asia's tallest self-supporting structure. Inaugurated in 2022, it takes the form of a lotus flower, a symbol of purity and renewal in Sri Lankan culture. For 20 USD, you can access the observation platform on the 29th floor to enjoy a panoramic view of Colombo and its surroundings.

Gangaramaya Temple

After exploring Beira Lake, head to the Gangaramaya Temple

The visit provides access to the main temple, inside which you'll find numerous objects (statues, relics, jade and ivory jewelry, sacred fabrics and manuscripts...) that make it feel like an antiques market. You can also see a sacred tree, a symbol of spiritual awakening (bodhi tree) from Anuradhapura.

Still have time? 

End your day on the Galle Face Green lawn to watch the sunset over the ocean! It's the gathering spot for both locals and tourists. You'll see children flying kites and families picnicking. The perfect way to finish your day beautifully and get a true taste of Sri Lankan culture before continuing or ending your trip!
