The first day I would build
Keep the opening route compact enough to feel like a city, not a scavenger hunt.
- Start in Old Town before the lanes get busy.
- Use Central Market when you are already near the station or river.
Begin with Old Town while your legs are fresh and the streets still feel crisp rather than crowded. Riga rewards small turns: a church spire, a quiet courtyard, a warm bakery window, then another narrow lane that pulls you forward.
After that, let Central Market and the Daugava edge widen the day. The market gives Riga a practical pulse, while the river helps reset the map in your head. I would not cross the city for one extra stop unless it clearly improves the evening.
