If you are interested in tropical plants, the Cairns Botanic Gardens definitely won’t let you down as it’s one of the best exhibitions of tropical plants in Australia. I liked the Aboriginal Plant Use Garden and the orchid garden. Just walked and explore the beauty of tropical plants and learn about tropical flora and horticulture. Saw lots of different types of butterflies too. We spent 2 hours in the garden and we really enjoyed our time there. We also stopped for a coffee in the garden cafe as a break. It’s a good place to spend with family.
