Stand at the northern end of Galle Face Green as the light goes orange over the Indian Ocean and you will see the whole city arranged in front of you: kite flyers, food vendors, families, and the traffic of Galle Road behind. That strip of grass between the road and the sea is where Colombo comes to unwind, and it is the best single introduction to the city.
Colombo suits travellers who want a South Asian capital they can walk in pieces rather than in one go: colonial churches and Dutch-era buildings, temples of several faiths, a lake at the centre of the city, and a promenade for the evening. It rewards a slow day of moving between districts rather than a checklist.
This guide covers the sights named in the source material, grouped by what is worth your time, followed by a one-day plan and answers to common questions.
Top things to do in Colombo
1. Galle Face Green Promenade
A half-kilometre promenade stretching between Galle Road and the Indian Ocean, and the largest open space of its kind in the city. 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.
Come at sundown for the view. If you want space to yourself, choose a weekday; if you want the full crowd, come at the weekend.
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 that sits upon Beira Lake, along with Gangamaraya Park.
From here you get some urban and eccentric views of the surrounding skyline, including a look back at the Altair Sri Lanka apartment tower. Combine the temple with a walk along the lake shore.
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 that change every few seconds.
Go up for the view, and if you are in the area after dark, look at the tower itself rather than from it.
4. 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 tourist site.
It sits in the middle of Pettah, so pair it with a wander through the market streets around it.
5. The National Museum of Colombo
Also known as the Sri Lanka National Museum, in Cinnamon Gardens, and the largest museum in Colombo. Among its exhibits it contains regalia of the 17th-century Kandyan kings.
It opens Saturday to Thursday, 9AM to 5PM. Cinnamon Gardens holds several other sights, so plan more than one stop in the district.
6. Wolvendaal Church
One of the oldest churches built during the Dutch era, in 1749. The interior is decorated with Dutch furniture, including wooden carved pews, chairs, pulpit and lecterns.
This is a quiet stop rather than a busy one; go for the interior rather than the exterior.
7. The Dutch Period Museum
A small museum on Prince Street documenting Dutch colonial rule in Sri Lanka, with Dutch-inspired artefacts. It is nice but very small.
Open Saturday to Thursday, 9AM to 5PM. Because it is small, treat it as one part of a morning in the Fort and Pettah area rather than a destination on its own.
8. 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 is 200 m north of Sugathadasa Indoor Stadium, which makes it easy to place if you are navigating by landmarks.
9. St Andrew's Scots Kirk church
At No. 73, Galle Road, close to the High Commission of India. It was founded in the late 19th century and prospered during the colonial and post-colonial periods, when it was a centre for the Scots element in Colombo.
Its position on Galle Road means you can fold it into a walk along that artery.
10. St Michael and All Angels Anglican Church
Dedicated on 29 September 1887 and a landmark in Kollupitiya, at 159 St Michael's Road. It is a building of stone, mortar and wood, on the corner of Cameron Place and 100 m east of Kollupitiya Jumma Mosque.
Pair it with the mosque nearby, since the two are within a short walk of each other.
11. St Paul's Church
One of the oldest churches in Sri Lanka, on Galle Road in the Milagiriya district. It was built by the Portuguese as a Roman Catholic church and was known as Nossa Senhora dos Milagres.
Take a bus to the stop called Milagiriya; the church is at the corner of Dr Lester James Peries Mawatha Street.
12. Independence Memorial Hall
Also called the Independence Commemoration Hall, at Independence Square in Cinnamon Gardens. It is a national monument built to commemorate independence from British rule on 4 February 1948, and it houses the Independence Memorial Museum.
Open 9AM to 5PM. It is in Cinnamon Gardens, so combine it with the National Museum and the Natural History Museum.
13. The Natural History Museum
On Sir Marcus Fernando Mawatha in Cinnamon Gardens, featuring Sri Lanka's flora and fauna in dioramas.
Open Saturday to Thursday, 9AM to 5PM, and closed on all public holidays. Check the day before you go.
14. Colombo Lighthouse
On Chaithya Rd, open daily 9AM to 6PM. It used to look out over the coastline, but it 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, so it reads as an anachronism.
Go for that contrast between the old lighthouse and the reclaimed city around it.
15. Slave Island
A commercial suburb popular with locals and visitors alike, with shopping, eating and drinking places as well as many hotels. Malays, Sinhalese, Tamils and Burghers call the suburb home. Despite its name, it is not actually an island; it was a camp for African slaves during the Portuguese period, which is where the British-era name comes from.
The Slave Island railway station is a notable Victorian landmark from the British era. Many historical buildings have been replaced by modern high-rises or left to decay, so look for what remains.
If you only have one day
Morning. Start in Cinnamon Gardens at the National Museum of Colombo, then walk to the Natural History Museum and Independence Memorial Hall, which are all in the same district and open from 9AM. If you have time before lunch, add the Dutch Period Museum on Prince Street.
Afternoon. Move to Pettah and the Fort area. See the Jami-Ul-Alfar Mosque on Second Cross Street, then continue to Gangaramaya Temple and the adjoining Seema Malaka on Beira Lake, where you can take in the skyline views. If you want a higher vantage point, go up the Lotus Tower on the east side of the lake.
Evening. Finish at Galle Face Green Promenade. Arrive at sundown for the view over the Indian Ocean, and stay as the vendors and kite flyers fill the grass. From there, Slave Island is close by if you want dinner and a drink before turning in.
