A good public park gives people somewhere to walk, play and see the landscape, so a visit goes best with a little preparation. Check the weather and bring water, sun protection and sturdy shoes, since park tracks on hillsides can be steep or slippery. Quiet weekday mornings suit walkers and photographers, while weekends and school holidays bring families, so go early for parking. Look for signs about dogs, fires and track conditions, and take rubbish home. If you are interested in nature or views, a council park page or local signage usually lists tracks and features.
For a walk or a family outing in Redcliffs, Barnett Park is a well-rated local green space.
