The Pinggan Viewpoint looks unreal, from here you can see Mount Agung and Mount Batur. The area is breathtaking, has not been explored by many tourists yet and doesn't require any hiking. The viewpoint is located in the Pinggan village in Kintamani area, 1 hour from Ubud. I stayed in Kintamani which I can highly recommend. It is a unique area with almost no tourists, different sightseeing spots and it is only 25 minutes from Pinggan viewpoint.
There are different platforms and views in this area so I recommend coming early for sunrise to pick out the best spot.
