This place is not just a collection of fish, but part of an ambitious project to improve the banks of the Diyawanna Oya River. Where there were once swamps, there is now a picturesque green zone with modern infrastructure. The main feature of the aquarium is its design, which allows visitors to literally take a round-the-world journey through the life of local water bodies.

Thanks to its location in the administrative capital, the aquarium has become an important cultural and educational site. Visitors can see rare representatives of local ecosystems, making this place a must-visit for families with children and all nature lovers wishing to learn more about the island's underwater treasures.

For your convenience, we have gathered up-to-date contact information to help you better plan your visit to this modern complex. Although the Diyatha Uyana Aquarium is part of an open park, having direct contact details allows you to clarify information about special events or visiting conditions. Below is the available contact data and the exact location of the site.

The main activity here is, undoubtedly, observing the inhabitants of the freshwater world. Walking along the circular walls of the aquarium, you can see in detail the fish and other creatures that inhabit the country's rivers and lakes. It is an excellent chance to see the diversity of local nature in one place without leaving the city.

After getting acquainted with the underwater residents, it's worth taking a stroll through Diyatha Uyana park itself. Here you can engage in active recreation: go for a run along the well-kept paths, take a boat trip on the river, or have a cozy family picnic on the grass. For children, there is a modern playground on the territory.

Don't miss the opportunity to dine at the unique floating restaurant or stop by one of the many cafes to try local delicacies. If your visit falls in the evening, you will witness a vibrant musical fountain show, whose colorful jets create a truly magical atmosphere under the open sky.

Diyatha Uyana Aquarium is located in the administrative capital of the island nation, Sri Jayawardenepura Kotte, making it easily accessible for residents and guests of nearby Colombo. The exact address is: WW36+FCQ, Sri Jayawardenepura Mawatha. A helpful landmark for drivers is the B240 road, along which the park is situated.

The most comfortable and fastest way to get here is by using taxi services or the island's popular tuk-tuks. A trip from central Colombo takes very little time, as Kotte is effectively a suburb of the metropolis. If you prefer public transport, choose buses heading towards the administrative center, but be prepared for a short walk from the stop to the park entrance.

The history of this site began in 2012, when the government initiated a large-scale land development project. In place of the modern park and aquarium, there were once abandoned and impassable marshes along the banks of the Diyawanna Oya River. The transformation of this zone was an important step in refreshing the image of the new capital.

The creation of the Diyatha Uyana Aquarium served both aesthetic and ecological purposes. The architects successfully integrated modern structures into the natural landscape, maintaining a balance between urban infrastructure and the natural environment. Today, this project is considered a model for successful urban greening in Sri Lanka.

Interestingly, the circular shape of the aquarium was not chosen by chance — it allows visitors to observe the inhabitants of the water world from different angles, creating a sense of full immersion. Since its opening, the park has become a favorite leisure spot for both locals and international tourists who appreciate modern comfort and proximity to nature.

For a relaxed tour of the Diyatha Uyana Aquarium exhibit, you will need about 40–60 minutes. This time is quite sufficient to see all the freshwater inhabitants and enjoy the unusual circular design of the tank. However, keep in mind that the aquarium is just one part of a large park complex.

If you plan to walk along the park's well-maintained paths, visit the floating restaurant, or go for a boat ride, we recommend setting aside at least 2–3 hours for your visit. The evening time is particularly popular among tourists, as you can complement your fish viewing with watching the musical fountains and relaxing in an open-air cafe.

The Diyatha Uyana Aquarium and its surrounding park operate on a schedule that is surprisingly convenient for tourists — the site is open 24/7 (24 hours a day), seven days a week. This allows you to plan your visit for the early morning to avoid the heat, or for late in the evening when the area is beautifully illuminated.

Despite the 24-hour access to the grounds, it is worth remembering that the internal cafes, restaurants, and boat stations may have their own schedules, typically closing closer to midnight. However, the opportunity to walk by the water and look into the aquarium is available at any time of day.

Exploring the surroundings of Diyatha Uyana can significantly enrich your experience of visiting the capital. The area around Lake Diyawanna Oya is actively developing, offering tourists a combination of modern recreation areas, historical monuments, and natural spots.

Near the aquarium, you will find several interesting locations reachable on foot or within minutes by tuk-tuk. Here is a list of nearby sites to include in your itinerary:
