The first day I would build
Give the city one clear route before adding extras.
- Start with Dongjiang Lake and Suxian Ridge while energy is high.
- Use Gaoyiling Scenic Area as the natural reset instead of crossing town too early.
the easier plan is Suxian Ridge or city center first, Dongjiang Lake as its own block, Gaoyiling or Mangshan only with a clear transport plan. 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 hot spring areas just because it looked close on a map.
