Zoological Garden

Sri Lanka's National Zoological Gardens, commonly known as the Dehiwala Zoo, sits about 11 kilometres south of Colombo Fort in the suburb of Dehiwala-Mount Lavinia. Spread across roughly 30 landscaped acres, it is one of the oldest and most-visited wildlife attractions on the island, drawing more than 1.2 million visitors each year. Families, school groups, and curious travellers find it a calm counterpoint to the city's pace — a green corridor where mammals, birds, reptiles, and fish from across the globe live in naturalistic enclosures.

What is the history of the Dehiwala Zoo?

The zoo's origins trace back to the late 1920s, when German animal dealer John Hagenbeck — a member of the Hamburg-based Hagenbeck family long associated with circus and wildlife trade — purchased around five acres of land in Dehiwala. He used the property as a holding centre for wild animals destined for export to Europe, particularly to his brother Carl Hagenbeck, one of the continent's most prominent animal dealers at the time.

The collection quickly became a local attraction. The land expanded to approximately eleven acres, and the Sri Lankan government formally recognised the site as a public zoological garden in July 1936 when it purchased the property. From that modest beginning, the gardens have grown steadily into a 30-acre institution maintained under the Ministry of Environment.

What animals can you see at the Dehiwala Zoo?

The zoo houses a broad cross-section of species arranged across dedicated zones. Highlights include:

• Large mammals: elephants, hippopotamuses, giraffes, big cats including leopards and lions, and various primates.
• Reptile House: a dedicated reptilian section featuring crocodiles, monitor lizards, pythons, and other species native to Sri Lanka and beyond.
• Walk-through Aviary: a free-flight enclosure where visitors move through the habitat of dozens of bird species, many of them tropical.
• Butterfly Park: a contained garden where several butterfly species complete their lifecycle, offering close observation of pupae, larvae, and adults.
• Sea lions and penguins: among the more unexpected residents, these southern-hemisphere species are part of the aquarium complex.

For those interested in Sri Lanka's own wildlife beyond the zoo, the Elephant Transit Home in Udawalawe offers a very different — and entirely wild — elephant experience worth including on any itinerary.

What makes the Dehiwala Zoo Aquarium special?

The aquarium is arguably the zoo's most distinctive feature. It is widely cited as one of the most comprehensive public aquariums in Asia, exhibiting more than 500 varieties of aquatic life — freshwater, marine, and brackish — drawn from ecosystems around the world. Viewing tanks are arranged to allow observation from multiple angles, including side-lit displays that show fish behaviour in near-natural conditions.

Among the rarer species on display:

• Arapaima (Arapaima gigas): one of the world's largest freshwater fish, originating from the Amazon basin.
• Lungfish: an ancient lineage of fish capable of breathing atmospheric air through a primitive lung structure.
• Polypterus: a genus often described as a living fossil, with a body plan largely unchanged over millions of years.
• Large freshwater catfish and a range of invertebrates and aquatic plants displayed in themed tanks.

The aquarium also hosts sea lion and penguin enclosures adjacent to the main tank halls, providing an interactive dimension that is especially popular with younger visitors.

Is there an elephant show at the Dehiwala Zoo?

A daily elephant performance has long been one of the zoo's signature events, typically held in the late afternoon. The demonstration showcases the animals' learned behaviours and has been part of the zoo's programme for decades. Visitors should arrive a few minutes early to secure a good viewing position, as it draws large crowds, particularly on weekends and public holidays.

Animal welfare standards at zoological gardens worldwide have evolved considerably, and the zoo's management practices have been subject to ongoing review. Travellers who prefer to observe elephants in a more natural context may wish to compare this experience with sanctuaries and national parks elsewhere on the island.

When is the Dehiwala Zoo open and how do you get there?

The zoo is open every day of the year, including public holidays, from 8.00 a.m. to 6.00 p.m. It is located in Dehiwala, approximately 11 kilometres south of Colombo Fort along the Galle Road corridor.

The most straightforward way to reach the zoo is by taxi or ride-hailing service from central Colombo, which typically takes 20–40 minutes depending on traffic. The coastal rail line also stops at Dehiwala station, a short walk from the entrance. If the zoo forms part of a broader Colombo itinerary, it pairs naturally with a Colombo city tour that can be arranged through Lakpura.

How long should you spend at the Zoological Gardens?

A comfortable visit covering the main mammal enclosures, aquarium, aviary, and butterfly park takes around three to four hours. Visitors who want to attend the elephant performance and spend unhurried time at the aquarium should allow a full half-day, arriving by early afternoon. The grounds are shaded in parts by mature trees, which helps during the warmer midday hours, but lightweight, breathable clothing and water are advisable.

Tips for visiting the Dehiwala Zoo with children

• Arrive before 9.00 a.m. on weekdays to avoid school-group crowds at the aquarium.
• The butterfly park is small but very popular with young children — allow extra time there.
• Pushchairs and prams can navigate most of the paved pathways comfortably.
• Light snacks and beverages are available inside, but bringing your own water is recommended.
• Photography is generally permitted in open enclosures; check signage near glass-fronted tanks where flash can disturb the animals.

What else is worth seeing near the Dehiwala Zoo?

Dehiwala is well connected to several other Colombo-area attractions. The Colombo Lotus Tower, visible from much of the city, is a short drive north and makes a logical pairing on the same day. The beachfront at Mount Lavinia is only a few kilometres south and provides a pleasant place to wind down after the zoo. For travellers extending their journey along the coast, the turtle hatcheries around Kosgoda are worth factoring into the itinerary.
