The best waterfront walk does not need a destination. Start where the streets open onto the harbour, put the phone away for a few minutes, and let the pace of the water replace the pace of the road.
Look for the details that change from one visit to the next: a rope drying on a railing, the colour of a ferry reflected in a window, or the thin line of shade under a footbridge. Familiar places become interesting when you stop asking them to be spectacular.
For a comfortable afternoon, carry water, choose shoes with a little grip, and check the weather before heading out. After rain, stone steps and painted surfaces can be slippery. Turn back whenever the sky begins to close in.
Finish with a short note: one sound, one colour, and one thing you had not noticed before. A walk is easier to remember when it has a few ordinary details attached to it.
