The movement pattern that feels best
Let the city stay compact instead of stitching together too many corners.
- Walk Old Town, the Daugava edge, and nearby Centrs.
- Use trams or buses when Miera iela or a farther base enters the day.
Riga rewards walking because the city changes texture quickly: medieval lanes, open river light, market halls, then calmer central streets. The trick is not to walk everywhere; it is to know when walking stops adding charm and starts eating the day.
I would build each day around one side of the city first. If you start in Old Town, add Central Market or the river. If you start in Centrs, add parks, cafes, or Miera iela. Crossing back and forth makes Riga feel more tiring than it is.
