The University of Papua New Guinea campus in Waigani contains a notable botanical garden with a collection of native tropical plants, including orchids, palms, and rainforest species. The university grounds are open to visitors and provide a pleasant, shaded walk — one of the greener and more tranquil spots in a city that is otherwise short on public green space.
The garden is modest by international standards but valuable for anyone wanting to see labelled examples of PNG's extraordinary botanical diversity. The campus itself is architecturally interesting: a 1960s development built around a central plaza on the Waigani ridge, with views over the city.
