If you don't stay in Sanur, or don't stay in the hotel facing Sanur beach, and you would like to see the Bali sun rise, at least there are 3 accesses to Sanur beach. (Maybe there are more, but I just talk about access with bigger roads).
Jalan Hang Tuah (Hang Tuah Street)
Located in northern area of Sanur where hotel Grand Bali Beach is located. The beach is also popular with the local who spend their Sunday afternoon bathing in the beach. But, I am sure it is not crowded at all in the morning.
Jalan Segara Ayu (Segara Ayu Street)
Moving to the middle Sanur, there is another access called Segara Ayu Street. White sandy beach is at the end of the street where you can sit on the beach waiting for the sun rise.
Jalan Pantai Sindu and Jalan Kesuma Sari
The street next is called Jalan Pantai Sindu which located right in the middle of Sanur. Jalan Kesuma Sari is at the end or eastern part of Sanur.
Where is the best place to see the sun rise of all those streets? Any where is good. But I can say middle area is the place where you can see the sun exactly to your east, not in your north east or southern east.
Happy sun rising.
