Some of the major attractions are Kintamai & Ubud Tour, Uluwatu Temple Tour, Benoa Beach for water sports, Sunset dinner cruise & many more. For more Info dm me?
Tanah Lot ans Ulluwatu is not to miss. Ubud is an amazing place. Bali river Rafting is life time experience. I personally didn't enjoy Mount Batur and Kintamani tour. You can research more and decide if you want to add in Ur itinerary.
There are many Hidden amazing waterfalls and beaches. Unfortunately i do not have much info on this.
