The land on the other side of the map, that's north Bali. Although one-sixth of the island's population lives here, this vast region is overlooked by many visitors who stay cocooned in the south Bali−Ubud axis.
The big draw here is the incredible diving and snorkelling at nearby Pulau Menjangan. Arcing around a nearby bay, booming Pemuteran may be Bali's best beach escape. To the east is Lovina, a sleepy beach strip with cheap hotels and even cheaper sunset beer specials. All along the north coast are interesting little boutique hotels, while inland you'll find quiet treks to waterfalls.
Getting to north Bali for once lives up to the cliché: it's half the fun.
