This is the classic first-day walk: the Main Market Square, the Cloth Hall, St Mary's Basilica and up to Wawel. A guide fills in the history that the buildings alone won't tell you – on your own, you'd walk past most of it without knowing what you were looking at.
What the route actually covers
Most tours start at the Main Market Square, Europe's largest medieval town square, then take in the Cloth Hall (the long Renaissance trading hall through the middle), St Mary's Basilica and its hourly trumpet call – played live from the tower, cut off mid-note in memory of a medieval trumpeter shot mid-warning – and the narrow streets leading up to Wawel hill. Some routes fold in the Barbican and remaining city walls, or a stop in the university quarter. The exact path varies by operator, but the square-to-Wawel spine is standard.
Small-group, private, or free
Small-group tours are the most-booked option: a fixed departure time, a guide, capped numbers so you can actually hear and ask questions. Private tours cost more but let you set the pace and skip anything that doesn't interest you – worth it for families or anyone who wants flexibility. Free, tip-based tours run daily too, and are exactly what they sound like: pay what you think it was worth at the end. They suit a tight budget, but expect a bigger group and looser timing than a paid option.
Timing, and what not to combine it with
Book a morning slot to beat the midday heat and the tour-bus crowds, then use the rest of the day for museums, Wawel's paid exhibitions, or a Kazimierz food tour. Kazimierz is usually its own separate tour rather than an add-on to this one – it's a different district with a different pace and focus (food, nightlife, Jewish heritage), so trying to fold it into the same route rushes both.

Yes, especially on your first day. A guide links the Old Town, Wawel and Main Square into one story and points out what you would otherwise miss.
