The first day I would build
Keep the city day practical and save Yercaud for a real route.
- Use Five Roads or Swarnapuri as the city-side anchor.
- Add Sugavaneswarar or Kottai Mariamman Temple when the route stays compact.
- Treat Yercaud as a separate hill trip, not a late add-on.
Salem becomes more useful when the first day is honest: arrival, a practical base, one temple or local stop, food, and an easy return. It does not need to pretend to be a dense monument city.
Yercaud is the tempting extra, but the climb and timing deserve their own plan. If you try to bolt it onto a full city day, both Salem and Yercaud can feel thinner than they should.
