Renowned for its huge rolling waves, Nusa Lembongan is a top surfing spot (experts only) from April to September. When the waves are at their strongest, you can watch the ballet of the tiny silhouettes on the foam opposite Jungutbatu, beyond the coral reef at the Shipwreck, Lacerations and Playground spots. Diving is popular at Ental Point, where, from August to October, the luckiest may catch a glimpse of the enormous (1t) moon fish (mola mola).
