Rather than only visiting the typical touristy spots, try the following and discover the real, authentic Bali that I love so much:
Rent a motorbike
Rent a motorbike instead of a car and explore some of the hidden villages of North Bali. I recommend to drive from the Lovina area to Munduk and Mayong Village. Along the way you can enjoy the fantastic lush scenery. Always drive slowly and be careful though.
Organize a walk or bike tour with a local guide.
Even if this can be a bit touristy it will still give you an impression of the real Bali. You will experience the heat, the smell of herbs and food that is cooked on the street. You will interfere with locals and have fun. Balinese are extremely friendly people. They will always wave at you when you pass by their village and will be happy to talk to you.
Have lunch in a local Warung.
Taste the real local flavors and get in touch with some locals. They will be more than happy to help you with the menu . Also stopping at one of the street food shops is amazing. For recommendations about what to order you can also check my blogpost on the best Balinese dishes and best tropical fruits to try in Bali.
Interact with locals
Participate in a local ceremony.
Ask locals about possible ceremonies in the village. Most Balinese are very open and will be happy to explain you about upcoming ceremonies or temple visits. Very often you can even take part of their ceremonie as long as you show respect and wear appropriate attire (sarong, praying belt around the waste for wowen, barefoot, no sleeveless shirts)
Everybody knows Ubud, or at least the touristic part of it. However it is very interesting to visit and explore all the small villages around Ubud. Every village has a specialty: painting, wood or stone carving, puppet making, etc. These villages are the best places to buy authentic artwork and handicraft items. Best is to simply drive through the villages and stop wherever you see nice handycraft that you like.
On their day off, many locals will gather at the lakes or at the hot springs. Bathing in these hotsprings, together with the locals is a truyl Balines experience. I recommend the Air Panas Hot Springs at Banjar. The water of the springs is considered "holy" by the locals. It is pleasantly warm at about 38° Celsius and is slightly sulfurous. The hot springs are the perfect place to meet locals and to enjoy life together with them.
