Free gardens and river outlook
Ask for the day's open outdoor circuit, then take the gardens and lakes at an easy pace before heading toward the river viewpoint. Stop for one close look at plants and one longer period of bird observation. Return whenever your group needs shade or a break; there is no reason to complete every path. The operator describes a 100-metre river boardwalk, not a 100-metre total park walk.
About 60–90 minutes, editorial estimate.
