Distinguish exploring from connecting
Look at the route between two itinerary stops. A riverside path, shopping street or chain of squares can be part of the visit. A long stretch beside a major road may simply consume energy you would prefer to spend elsewhere.
Choose one or two walkable clusters and connect them by transit when the gap is unappealing. This avoids treating every mile as equally valuable. In a spread-out city, a short ride can protect time for a slower neighborhood walk instead of turning sightseeing into a distance target.
Compare the whole effort
A short metro ride can involve a long platform walk, a wait and another exit passage. For a brief journey, walking may be equally straightforward. Use the street map as well as the transport diagram; diagram spacing is not a reliable distance measure.
Account for hills, crossings, weather and surface. A route that looks short can climb sharply or cross a bridge with limited access. If stairs are a problem, consult an official step-free route rather than assuming the metro saves effort.
Keep the return flexible
Energy changes during sightseeing. Plan the walk you care about while you are likely to enjoy it, and retain transit for the return. This is useful after a museum, where indoor walking may have been longer than expected.
Know a nearby station or stop and its direction home. Do not wait until everyone is exhausted to discover the closest platform serves the wrong branch. A small transport allowance makes changing plans easier without turning the decision into an argument.
Let the modes differ
You need not use the same mode both ways. Walk downhill toward the center and ride back, or travel outward and return through a district you want to explore. Verify that the chosen service operates when you need it.
One purposeful walk can make a day coherent. Several additional connecting walks may only make it tiring. Judge each section by what it adds, and leave room to stop at a café, take shelter or abandon the route when it no longer feels enjoyable.
