Colombo, on the west coast of Sri Lanka, is the country’s commercial capital and the gateway for most travelers: Bandaranaike International Airport lies north of the city, near Negombo. Many people pass through too quickly, yet there are plenty of things to do in Colombo: one or two days are enough to see the colonial Fort district, the Pettah bazaars, Gangaramaya temple and the Galle Face seafront before heading on to Kandy, the Cultural Triangle or the southern beaches. Before you land, apply for your ETA: the process is explained on our Sri Lanka visa page.
This guide covers what to do in Colombo in one or two days, the climate based on official normals and a table of expected rain over a short stay, a useful check if you are planning a night or two on arrival or before your flight home.

Things to do in Colombo: the top sights
Fort, the colonial district
The Fort district stands on the site of the former Portuguese and later Dutch fortress. You can see restored colonial buildings, including the old Dutch Hospital, turned into a complex of shops and restaurants, as well as the presidential residence and the clock tower lighthouse.
Pettah and its bazaars
Just east of Fort, Pettah is a maze of specialized shopping streets: fabrics, spices, electronics, fruit. Here you will find the Jami Ul-Alfar mosque, recognizable by its red and white bricks, and the Dutch Museum. Come in the morning, when it is quieter, and watch your belongings in the crowds.
Gangaramaya temple and Beira Lake
The Buddhist Gangaramaya temple mixes Sri Lankan architecture, Thai and Chinese influences and an astonishing collection of objects donated by worshippers. Next door, on Beira Lake, the small Seema Malaka temple, set on the water, completes the visit.
Galle Face Green
This long oceanfront lawn is where locals stroll in the late afternoon: kites, street food stalls, sunset over the sea. Swimming here is not an option.
The National Museum and Viharamahadevi Park
The Colombo National Museum covers the island’s history, from the ancient kingdoms to the colonial period. It borders Viharamahadevi Park, the city’s largest public garden, in the leafy Cinnamon Gardens district.
The Lotus Tower
Completed in 2019 and 350 m (1,148 ft) tall, the lotus-bud-shaped tower has become a landmark of the skyline. An observation deck offers views over the city and the coast.
Mount Lavinia
South of the city, Mount Lavinia is known for its beach and its colonial hotel. Be careful: according to the UK FCDO (GOV.UK, updated 21 September 2026), many beaches in Sri Lanka have dangerous surf or rip tides at certain times of the year; get advice from your hotel before going in the sea.
