The dry season from April to October is the best time to visit, with calmer seas, reliable fast-boat crossings, and clearer water for snorkeling and diving. July and August are peak: busiest viewpoints, highest prices, and the prime window for spotting the rare mola mola (sunfish), which appear roughly July to October. The wet season (November to March) brings short, heavy downpours, slippery cliff trails, and occasionally cancelled boats, though it is quieter and cheaper. For the best balance of weather and smaller crowds, aim for April to June or September. Manta rays are seen year-round.

Almost everyone arrives by fast boat from Sanur, a 30 to 45 minute crossing costing roughly 150,000 to 350,000 IDR (about $10 to $25) each way, landing at Banjar Nyuh or Toyapakeh harbor; boats also run from Padang Bai and Nusa Lembongan. Book a morning departure and keep your return ticket flexible, as rough seas can disrupt schedules. On the island, the roads range from decent to brutally potholed, so rent a scooter only if you are a confident rider (helmets are essential and accidents are common). Most visitors hire a private driver with car for around 600,000 to 800,000 IDR per day, or join a full-day island tour. There are no ride-hail apps reliably operating here, so arrange transport in advance.
