The first day I would build
Give the city one clear route before adding extras.
- Start with Stolby Nature Reserve and Yenisei River while energy is high.
- Use Paraskeva Pyatnitsa Chapel as the natural reset instead of crossing town too early.
the easier plan is Stolby as its own outing, or Yenisei and Paraskeva Chapel for the city route. 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 city center just because it looked close on a map.
