Snorkeling & Diving in Bali
Bali is one of Southeast Asia's great underwater playgrounds, with warm, clear water and dive sites for every level. Swim with graceful manta rays year-round at Nusa Penida, explore the coral-encrusted USAT Liberty WWII shipwreck at Tulamben straight from the shore, and drift over healthy reefs at Menjangan Island, Amed and the Gili Islands. This guide covers the best snorkelling and diving sites, when to go, what it costs and how to choose a safe operator — whether you're a first-time snorkeller or a certified diver.
Frequently Asked Questions
Do I need a diving certificate to dive in Bali?
No. If you are not certified you can still do a 'Discover Scuba' try-dive with an instructor to about 12 metres, no experience needed. To dive independently you take an Open Water course (2–4 days). Snorkelling needs no certificate at all.
Can non-swimmers or beginners snorkel in Bali?
Yes. Calm, shallow spots like Blue Lagoon in Padang Bai and Crystal Bay in Nusa Penida are ideal for beginners, and all reputable operators provide life jackets and guides so weak swimmers can join safely.
Where and when can I see manta rays and mola mola?
Manta rays are seen year-round at Manta Point off Nusa Penida. The rare mola mola (ocean sunfish) appears in the cooler upwelling season, roughly July to October, mostly around Crystal Bay and Gamat Bay.
When is the best time for snorkelling and diving in Bali?
The dry season from April to November has the calmest seas and best visibility. Water is warm (26–29°C) all year, though Nusa Penida can have cold, strong currents, so those sites suit stronger swimmers and divers.
How much does snorkelling and diving cost in Bali?
A shared snorkel day trip starts from about USD 25–45. A guided try-dive for beginners is USD 80–110, a two-tank fun dive for certified divers is USD 70–100, and a full Open Water certification course runs USD 400–500. Prices usually include gear, a guide and boat transfers.
Do I need to bring my own snorkel or dive gear?
No. Every reputable operator provides masks, fins, snorkels, life jackets and — for divers — a full set of scuba equipment. If you prefer your own mask for a better fit you can bring it, but it is not required. Just bring swimwear, a towel and reef-safe sunscreen.
