Banff National Park , Canada Itenary Recommedation

I’m planning to visit Banff, Alberta at the end of June 2026. The trip will be 3 days and 2 nights, exploring Banff and its surroundings. Yes we will be considering Rental car to travel around.

Could you suggest some must‑see places? Also, are there any passes available that provide access to tourist attractions?

P.S. This will be my first time visiting Canada, and it will be a family trip.
