The first day I would build
Give the city one clear route before adding extras.
- Start with Galle Face Green and Pettah Market while energy is high.
- Use Gangaramaya Temple as the natural reset instead of crossing town too early.
the easier plan is Fort and Pettah first, Gangaramaya or Independence Square next, Galle Face for the evening. That keeps the day readable instead of turning every good name into a separate detour.
I would rather leave one place for tomorrow than drag a tired route through Independence Square just because it looked close on a map.
