Stand at the northern end of Galle Face Green as the light drops and the whole promenade fills: kite flyers, vendors, families, couples, all of them strung out along the strip of grass between Galle Road and the Indian Ocean. Behind you the towers of the financial district catch the last of the sun, and the sea breeze carries the smell of frying snacks from the carts.
Colombo suits travellers who want a city with layers rather than a single set piece. It is Sri Lanka's executive and judicial capital and its financial centre, and the Portuguese, Dutch and British presence is still legible in its architecture, names, food and language. It is also a city of holy places, museums and colonial-era buildings, with the coast and Beira Lake shaping how you move through it.
This guide covers the sights and experiences worth your time, drawn from what is documented about the city, followed by a plan for a single day if that is all you have.
Top things to do in Colombo
1. Galle Face Green Promenade
A stretch of open land along the Indian Ocean coast in the heart of the city, running between Galle Road and the water. It draws children, teenagers, vendors, kite flyers and families, and on Saturday and Sunday evenings it fills with day-trippers, food vendors and people picnicking.
Go at sundown for the view. If you want space rather than crowds, avoid the weekend evenings, when it becomes very busy.
2. Gangaramaya Temple and Seema Malaka
One of the most important temples in Colombo, with architecture that mixes Sri Lankan, Thai, Indian and Chinese styles. Adjoining it to the west is Seema Malaka, a Buddhist temple complex sitting on Beira Lake, along with Gangamaraya Park.
From here you get some unusual views back over the surrounding skyline, including the Altair Sri Lanka apartment tower. Combine the temple with the lake-side complex and the park in one visit.
3. Lotus Tower
A distinctive telecommunications tower on the east side of Beira Lake that offers great views over the city. At night it is lit with colours on the flower shape, changing every few seconds.
If you are a foreign visitor, note that the admission price is considerably higher than the rate for Sri Lankans. Going after dark lets you see the tower lit as well as the city lights.
4. The National Museum of Colombo
Also known as the Sri Lanka National Museum, this is the largest museum in Colombo, in Cinnamon Gardens. Among its exhibits it holds the regalia of the 17th-century Kandyan kings.
It opens Saturday to Thursday, 9AM to 5PM. Pair it with the other Cinnamon Gardens sights on the same day.
5. Jami-Ul-Alfar Mosque
A historic mosque on Second Cross Street in Pettah, built in 1909 by the Pettah Muslim community to serve their required five-times-daily prayer and Jummah on Fridays. It is one of the oldest mosques in Colombo and a popular site for visitors.
It sits in Pettah, so combine it with a walk through the surrounding commercial streets and the area's market life.
6. Wolvendaal Church
One of the oldest churches built during the Dutch era, on Galle Road in Colombo 06, dating to 1749. The interior is decorated with Dutch furniture, including wooden carved pews, chairs, pulpit and lecterns.
Come for the interior rather than the exterior alone; the carved woodwork is the reason to make the trip.
7. St Lucia's Cathedral
The seat of the archbishop of the Roman Catholic Archdiocese of Colombo, on St Benedict's Street and St Lucia Street in Kotahena, in the northeast of the city.
It stands about 200 m north of the Sugathadasa Indoor Stadium, which makes the stadium a useful landmark when you are finding your way there.
8. St Michael and All Angels Anglican Church
Dedicated on 29 September 1887, this is a landmark in Kollupitiya, a suburb of the commercial capital. It is a building of stone, mortar and wood, at 159 St Michael's Road, Colombo 3.
It sits on the corner of Cameron Place, about 100 m east of Kollupitiya Jumma Mosque, so the two can be seen in the same short walk.
9. St Andrew's Scots Kirk church
Founded in the late 19th century at No. 73, Galle Road, Colombo 3, this church prospered through the colonial and post-colonial periods and was a centre for the Scots element in the city.
It is close to the High Commission of India, which helps you place it along Galle Road.
10. Dutch Period Museum
A small museum at 95 Prince Street, Colombo 01, documenting Dutch colonial rule in Sri Lanka and housing Dutch-inspired artifacts. It is nice but very small, so treat it as a short stop.
It opens Saturday to Thursday, 9AM to 5PM. It sits in the Fort and Pettah area, which you can pair with the Jami-Ul-Alfar Mosque.
11. Independence Memorial Hall
Also known as Independence Commemoration Hall, this national monument at Independence Square in Cinnamon Gardens was built to commemorate independence from British rule with the establishment of the Dominion of Ceylon on 4 February 1948. It also houses the Independence Memorial Museum.
It is open 9AM to 5PM, and its Cinnamon Gardens location makes it easy to combine with the National Museum of Colombo.
12. Kelaniya Raja Maha Viharaya
Located about 9 km from Colombo, this is one of the most significant Buddhist temples in Sri Lanka. It was built more than 2,000 years ago and contains images of the reclining and preaching Buddha along with frescoes depicting incidents from his life.
Because it lies outside the city, allow for the journey there and back rather than treating it as a quick stop.
13. Colombo Lighthouse
On Chaithya Road, open daily 9AM to 6PM. It once looked out over the coastline, but is now hemmed in by the urban centre to the east and the new Colombo International Financial City built on reclaimed land to the west.
That setting is the point of the visit: you are looking at a lighthouse that has been overtaken by the city around it.
14. Slave Island
A commercial suburb popular with locals and visitors alike, with shopping, eating and drinking places and many hotels. Malays, Sinhalese, Tamils and Burghers all call it home, and despite the name it is not actually an island.
During the Portuguese period the area was a camp for African slaves, and the British gave it its name; the Slave Island railway station, a notable Victorian landmark, dates from the British era. Many historical buildings have since been replaced by high-rises or left to decay, so look for what remains as you walk.
15. Victoria Masonic Temple
The meeting place for the Masonic Lodges at Galle Face, Colombo 03. It was built in 1901 during British rule, designed by E. Skinner and built by the Colombo Commercial Company, in a neo-Georgian style mixed with elements of Eastern architecture.
It is at Galle Face, so it fits naturally into a walk that includes Galle Face Green.
If you only have one day
Morning: Start at the National Museum of Colombo in Cinnamon Gardens when it opens at 9AM, then walk to Independence Memorial Hall at Independence Square, which also opens at 9AM and houses the Independence Memorial Museum.
Afternoon: Move to Pettah and the Fort area. See the Jami-Ul-Alfar Mosque on Second Cross Street, then the Dutch Period Museum on Prince Street, which is small enough to fit into the same afternoon. If time allows, continue to Gangaramaya Temple and the adjoining Seema Malaka on Beira Lake.
Evening: Finish at Galle Face Green Promenade for sundown, with the Victoria Masonic Temple nearby at Galle Face. If you want the view over the city after dark, the Lotus Tower on the east side of Beira Lake is lit with colours that change every few seconds.
