This is an absolutely beautiful place that seems less trafficked than the nearby Manoa Falls. You will probably need to park at the Manoa Falls parking lot below which costs $5. When you get up to the Arboretum visitor center, there is a suggested $5 donation, but I don't think it is required. Even with the donation, it is well worth it. There are plenty of beautiful views and a diversity of plant life. This is a good place to come and hike for a while. There are established, paved gravel trails but there are also some fun trails that are a little more wild and less paved.
One of the top Botanical gardens on island. For a $5 donation you can walk through acres of tropical plants, many native Hawaiian, all the way to a small, but beautiful waterfall. Not stroller friendly, as the paths are gravel. Many paths are not maintained. Put on bug spray before starting out!
