Harold Boas Gardens is one of Perth’s quieter green spaces, with a lake, cascade and mature trees close to city streets. It is a good choice when a big riverfront lawn is more than you need. Sit by the water for a while, then explore the paths rather than rushing through for a single photograph.

A small garden with a layered history
The City’s visitor description records the former name Delhi Square and a 1976 redevelopment that retained many trees planted around 1900. The changes explain the mixture of old canopy and later water features. Look for differences between the built cascade and the surrounding planting. A waterfall feature may operate differently during maintenance or dry conditions, so the garden itself is the dependable reason to visit.
Take the slower route
Paths, pond edges and lawn offer different surfaces. If you are visiting with a wheelchair, pram or someone who tires easily, choose the firmest path and avoid assuming every garden edge is level. Do not enter the pond, and supervise children close to the water. City parks sometimes host booked events; check on-site signs for a section in use. Pair the garden with John Oldham Park if you want another pocket of water and trees closer to Mounts Bay Road.
