What this solves
Most "learn to dive in Bali" pages quote Open Water at Rp 4–6m and stop there. They don't tell you that Crystal Bay (Nusa Penida) is a drift / down-current site that requires Advanced + a Deep specialty before reputable shops will take you; that Tulamben USAT Liberty wreck is open-water accessible but the deeper reaches need AOW; that Amed's Japanese wreck sits at 30+ m and demands Deep cert. This tool chooses the right cert path for the site you actually want to dive.
Who it's for. Travellers planning their first / next cert; divers eyeing a Bali trip and wondering what to upgrade before they fly; parents checking whether their 14-year-old can get OWD; anyone budgeting a dive trip in IDR vs USD.
Plan your cert path
How to read the result
- Path shows the cert steps in order, with the budget per step in IDR. Skip a step only if you already hold it.
- Site cert requirement is the minimum shops ask before they take you on a boat. Some sites (Crystal Bay, Gili T deep slopes) enforce the practical standard regardless of what's on your card.
- Month / visibility matters: dry season gives 25–30 m+ at Tulamben and Menjangan; wet season drops to 10–15 m. Cold thermoclines (Nusa Penida, Aug–Oct) require a 5 mm wetsuit.
- Shop considerations — what to ask before booking, what the inflated "tourist" prices hide.
Limitations
- Cert prices vary by 30–50% across operators. A reputable small shop (e.g. local PADI 5-star in Sanur or Tulamben) is similar in quality to a big operator but cheaper. The IDR figures are 2026 mid-range.
- Nusa Penida's "Manta Point" is technically accessible to AOW divers, but the currents at Crystal Bay require experienced AOW + Deep cert + a divemaster guide. Don't skip the cert based on the headline "AOW needed".
- Medical fitness to dive is not modelled here. Pregnancy, certain cardiac / pulmonary conditions, and recent surgery are absolute contraindications. DAN (Divers Alert Network) pre-dive medical is recommended.
- This tool does not substitute for a proper check-in with a dive shop about your logged dives, recent activity, and comfort level. Reputable shops will turn you away from a site that's above your comfort even if your card says you can.
FAQ
Can I get Open Water certified in 3 days?
Yes. PADI / SSI OWD in Bali is typically 3 days: 1 day academics + pool, 2 days open-water dives (4 total). Most shops run a Mon–Wed or Fri–Sun schedule. Expect Rp 4.5–6m including manual, card, and 4 boat dives. The card fee is included. Be wary of "Rp 2.5m OWD" — usually a stripped-down course with shared equipment and minimal pool time.
What's the minimum age for OWD?
PADI / SSI Junior OWD is 10+. AOW is 12+. Divers aged 10–14 have a depth limit of 12 m and must dive with a certified adult. Most Bali dive shops will book a 12+ for full OWD and AOW programmes; under-12 typically needs a private instructor (Rp 1–2m surcharge on top).
Should I do AOW in Bali or at home?
If you're already in Bali for a week and have OWD + 4 logged dives, doing AOW here makes sense — you dive in actual conditions instead of cold quarry water. Costs roughly Rp 4–5.5m for the 5-dive adventure-dive programme (deep, navigation, plus 3 electives). If you have time at home, doing it in colder / cheaper water and then doing fun dives in Bali saves IDR 2–3m.
What's the mola mola season and what does it require?
July through mid-October, with peak sightings late July through August. The mola mola (ocean sunfish) come up to the cooler, nutrient-rich thermocline at Nusa Penida / Nusa Lembongan. Depth is usually 15–30 m, water temp drops to 18–22°C. You'll need AOW + Deep cert + 5 mm wetsuit and reasonable experience in currents. Expect Rp 4.5–6.5m for a 2- or 3-dive package at a reputable shop — half the dives will be "mola scouting" with no guarantee of a sighting.
