Start with a small radius
Choose a neighbourhood you can reach easily and give yourself ninety minutes. A compact area makes room for wandering without spending the whole day in transit. Start near a park, a market or a pedestrian street, then let one interesting detail lead to the next.
Save your starting point on a map, check how you will get home and keep a little battery in reserve. The aim is a pleasant detour, not a complicated expedition.
Follow a theme, rather than a checklist
Look for three independent bookshops, a favourite piece of street art or the best-looking courtyard. A theme gives a walk direction while leaving space for surprises. Architecture, old shopfronts and public gardens are good starting points that do not depend on buying anything.
Notice what makes a place feel welcoming: a bench in the shade, an unhurried café, a library with a community noticeboard. These are places worth returning to.
Leave room for one conversation
Ask a bookseller which shelf they would start with, or a café team which quiet time they recommend. Keep it brief, be considerate when someone is working and let the conversation end naturally. Curiosity works best without an agenda.
If you explore with someone else, take turns choosing the next stop. You will each notice something the other would have walked straight past.
Make a tiny city notebook
Keep a note of one place to revisit, one thing you learned and one idea for another day. You do not need a perfect photograph or a public post. A city becomes more interesting as it becomes familiar.
A good first route: a local library, a short walk through a park and a drink somewhere independent. Check opening hours before setting out.
