The Beaches on the East side of Nusa Penida are little further than the West Side from the harbor. Nonetheless the road on the way there is a lot better than the West side. Going there in an Air-conditioned car is most comfortable as day-time temperature can be a little bit high. Alternatively you can go there on motorbike.
Diamond beach is the best beach of all on the East. You can take spectacular photos from above the hill, then go down to the beach through stairs provided by the local. At the beach you can take another amazing photo while swinging above the ocean, or take a dip to the crystal clear and white sandy beach. This place is so instagramable!
