The premises are well-kept and clean and it is a public outdoor space that gives the opportunity for people from all walks of life to hang around, chat and enjoy their time at Diyatha Uyana. Many people go to Diyatha Uyana during the evening as the sun set and the shimmering waters of the Diyawanna Lake which is adjoining the Diyatha Uyana make the experience all the more perfect. The aquarium at Diyatha Uyana attracts many kids and especially during the evening crowds gather around the circular aquarium as it offers a moment of tranquillity to the city dwellers’ lives. However, this is not something as gigantic and high-tech as the aquariums you see in countries such as Singapore nor can you expect exquisite fish to swim to and from in these tanks. But the concept is a fresh idea to Colombo and it is very well maintained so a quick stroll around the aquarium would be nice on a lazy evening.
