4 day itenerary for Bali

Hi!
I am planning a 4 day trip to Bali with my (retired) parents. Can someone please help me create an itenerary that is not crammed with just beach visits or focused on nightlife. My folks are into temples and local culture and stuff. We would also like a taste of the best local food.

All of what i have found on the net seems to be beach focused!

Also, is candidasa okay to stay in, accessibility wise? Any suggestions/ recommendations would be most helpful.
