Bali sits at the edge of the Coral Triangle, which is why a single island offers wreck diving in Tulamben, manta encounters off Nusa Penida, macro critters in Amed and Padang Bai, and calm reef training around Sanur and Nusa Lembongan. That variety matters when choosing a school, because the best instructor for your Open Water course may be based on the other side of the island from the dive site you most want to see. Conditions change between the east and west coasts, and between the dry season (April to October) and the wet season, so a good school tells you plainly what is realistic on the day you plan to dive.
The fifteen schools below were ranked on communication, service quality, pricing, reputation, and reliability. Ratings come from public reviews, and each listing links to a full profile on bestinbali.co. Scores between 4.7 and 5.0 are common among Bali dive operators, so the write-ups focus on what separates one school from another: location, group size, course range, equipment, and the kind of diver each school suits best.
Before booking, confirm which agency certifies the course (PADI, SSI, or another recognised body), how many students each instructor takes, and whether boat fees, equipment, and transfers are included in the quoted price. Those three questions prevent most surprises on the day.
1. Bali Diving School | Scuba Diving Course
Full-service dive centre covering courses, fun dives, and multi-site trips
Bali Diving School holds a 5.0/5 rating and positions itself as a complete training and trips operation. It runs beginner experiences, Open Water certification, and fun dives to the island’s best-known sites, including the USAT Liberty wreck in Tulamben, Crystal Bay and Manta Point at Nusa Penida, and the reefs of Nusa Lembongan. Having one school handle both training and the later dive trips means students can progress through certification levels without changing operators.
The school offers hotel pick-up for its trips, which matters on an island where a dive site can be two hours from your accommodation. Packages bundle courses with trips, so divers who plan to certify and then dive for several days can cover everything under one booking. Small groups are part of the pitch, and reviewers frequently mention patient instruction for nervous first-timers.
Pros
- Perfect 5.0/5 rating from public reviews
- Courses and multi-site dive trips under one roof
- Hotel pick-up arranged for most trips
- Suits complete beginners as well as certified divers
Cons
- Popular sites such as Manta Point can be busy in peak season
- Pricing varies by package, so request a written quote before booking

2. Diving in Bali – Bali Diving Academy
Academy-style training school with a strong 4.9 rating
Bali Diving Academy is a training-focused operation with a 4.9/5 rating. The academy format suggests a structured approach to teaching, from first breaths underwater through to advanced and professional-level courses. Divers who want to progress beyond Open Water, whether to Advanced Open Water, Rescue Diver, or beyond, will find the school set up for that pathway.
The academy also runs guided dives to the main Bali sites, so certified divers can book trips without enrolling in a course. As with most larger operators, the experience depends on the instructor assigned, so ask about group sizes and instructor languages when you enquire.
Pros
- 4.9/5 rating
- Structured course progression from beginner to advanced
- Guided trips available for certified divers
Cons
- No standalone website listed, so enquiries go through the directory listing or social channels

3. Adventure Scuba Diving Bali
Boutique operator focused on personal service and flexible itineraries
Adventure Scuba Diving Bali holds a 4.9/5 rating and operates on a smaller scale than the big-box dive centres. Smaller operators tend to offer more flexibility on dive sites and timing, which suits divers who want to chase specific conditions, such as visibility at Tulamben or current-driven drift dives at Nusa Penida, rather than follow a fixed daily schedule.
The school runs courses and guided dives, and reviewers commonly praise attentive guides and a relaxed pace. Divers with particular interests, such as photography or a first return to the water after a long break, are well served by an operator that can adjust the plan.
Pros
- 4.9/5 rating
- Smaller-scale service with flexible planning
- Good fit for divers who want a personalised itinerary
Cons
- Fewer departures than larger centres, so book ahead in peak months
- Limited accommodation or resort add-ons compared with bigger operators

S.E.A. Diving Bali carries a 4.9/5 rating and is known for an approach that combines recreational diving with attention to the marine environment.

DUNE Bali is part of the wider DUNE dive network and holds a 4.9/5 rating. Being part of a multi-location brand usually means standardised safety procedures, consistent equipment, and staff used to working with international guests.
The centre runs courses and guided dives, and the brand’s international footprint suits divers who plan to continue training elsewhere. Ask which Bali sites the centre dives most often, since the answer shapes both travel time and the kind of marine life you are likely to see.

PADI 5 Star centre based on the east coast at Padang Bai
Geko Dive Bali is a PADI 5 Star dive centre in Padang Bai with a 4.9/5 rating. The east coast location puts divers close to Blue Lagoon, Bias Tugel, and Jetty, sites known for good coral, macro life, and relatively gentle conditions, plus easy access to Nusa Penida and Nusa Lembongan by boat.
The PADI 5 Star status reflects an established training operation with a full course range. Padang Bai is also a working port, so it offers a very different feel from the resort areas in the south, and many divers prefer the quieter setting.

Who is the best dive schools in Bali?
Bali Diving School, KRISS Bali Diving, Planet Bali Dive, and Ocean King Dive Shop each hold a 5.0/5 rating, and Bali Diving School leads this ranking for its mix of courses, multi-site trips, and hotel pick-up. The right choice still depends on where you are staying, your certification level, and whether you prefer small groups or a larger centre. Geko Dive Bali suits the east coast, and Crystal Divers suits anyone planning a professional career.
How much does a dive school cost in Bali?
Prices vary by school, course, and season, and the operators above publish their rates directly or provide quotes on request. As a general guide, an introductory dive costs the least, an Open Water certification costs several times more, and professional courses such as Divemaster or Instructor cost the most. Ask each school what is included (equipment hire, boat fees, certification card, transfers, lunch) so you can compare like for like.
How do I choose a dive school in Bali?
Start with location, since transfers to sites such as Tulamben, Amed, and Nusa Penida can take two hours or more each way. Next, check the certifying agency, instructor-to-student ratio, and equipment condition. Read recent reviews for comments on safety briefings and communication, and message two or three schools to compare response times and clarity. A school that answers questions plainly before you pay usually runs its dives the same way.
What should I look for in a dive school?
Look for recognised certification (PADI, SSI, or equivalent), small group sizes for beginners, well-maintained equipment, and clear safety briefings. Confirm that instructors speak your language fluently and that emergency oxygen and first aid equipment are on every boat. Transparent pricing, a written itinerary, and honest advice about conditions and seasonal marine life are further signs of a reliable operator.
Are there good dive schools for small businesses in Bali?
Several schools on this list handle group bookings, including corporate retreats, team-building days, and resort or villa operators who want to offer diving to guests. Boutique operators such as Adventure Scuba Diving Bali and Bali Fun Diving can adjust itineraries for small groups, while larger centres such as Bali Scuba and DUNE Bali can handle bigger parties. Contact the school with your group size, dates, and experience levels to get a tailored quote.
Bali offers enough variety that most divers can find a school matching their level, location, and budget, and every operator ranked here has earned a rating of 4.7/5 or higher from public reviews. Shortlist two or three schools near your accommodation or preferred dive area, compare written quotes, and check the details on safety, group size, and inclusions before booking. Browse the full listings on bestinbali.co to compare further and contact schools directly.
