Uluwatu, Padang Padang, Green Bowl, Nusa Dua, Dream Land, Honeymoon, Bingin, Balangan. This site you can find around Bukit Jimbaran Area until Nusa Dua. Most of them have big Wave and nice views because go there you have to go through the hill.
Kuta - Seminyak. You can surf from Kuta beach until Seminyak Beach. Most of them are small wave. There is good for beginner. And you can surf close to the Airport.
Sanur Beach. Sometimes you can surf in Sanur, but depend on the wave. But Sanur is good for kite surfer or wind surfer because it has good wind.
Serangan. Actually Serangan is different island, but sometimes we are not realizing it is a different island because it's just a few meters from Bali Island. And Serangan is one of my favorite places in Bali because the way to Serangan is so green.
Berawa and Batu bolong. They are around Canggu Area. I think now Canggu is popular for tourist because when you go to Canggu it's like you out of Bali. Many foreigners living in Canggu.
