Bali
Bali packs a lot of variety into short road transfers from Denpasar (DPS), and access is mostly easy: shore dives and day-boats, no liveaboard needed. Tulamben, on the northeast coast, holds the USAT Liberty, a 120m WWII wreck lying about 30m off the beach with its shallowest deck around 5m, so it is a genuine Open Water shore dive. Nearby Amed adds black-sand muck and macro, and Menjangan in the far west offers calm marine-park walls. The headline animals are at Nusa Penida, a boat day-trip from Sanur. Reef mantas cruise the shallow cleaning and feeding stations at Manta Point through the year. From roughly July to October or November, cold upwelling at Crystal Bay and Blue Corner draws the ocean sunfish (Mola) into diveable depths, and that same upwelling can drop water into the low 20s or high teens with strong, unpredictable currents. Padang Bai and Gili Mimpang round out the mix with reef sharks and drift diving. The Nusa Penida belt is where Bali gets serious: down-currents and cold make several sites advanced-only, even though Tulamben and Amed suit new divers.
What makes it special
- USAT Liberty at Tulamben: a 120m WWII wreck about 30m off the beach, shore-entry, top of the wreck around 5m
- Reef mantas year-round at Manta Point's shallow cleaning and feeding stations, Nusa Penida
- Ocean sunfish (Mola) drawn up by cold upwelling at Crystal Bay and Blue Corner, roughly July-November
- Easy access: fly Denpasar, road transfers, and mostly shore or day-boat diving with no liveaboard required

Price is per person for a typical trip, excluding international flights ($ under $2,000 to $$ $2,000–4,000).
Land-based and budget-friendly. Two-dive fun-dive packages run roughly IDR 2.4-2.9M (about $150-180): Tulamben around IDR 2.4M, Amed IDR 2.56M, Padang Bai and Nusa Penida around IDR 2.72M, Gili Islands IDR 2.88M. Nusa Penida marine-park fee is about IDR 100,000 and Menjangan about IDR 200,000 weekday / 300,000 weekend, both extra. A week of guided diving plus modest accommodation comfortably lands under $2k per person excluding flights; higher-end resorts push it into the $$ band.
Best time to dive
- Current
- Moderate
- Water temp
- 19–29°C (coldest Sep, warmest Jan)
- Visibility
- 10–30m — Commonly 15-30m in the dry season (April-November); Menjangan's walls can exceed 30m at their clearest around October-November. Plankton-rich upwelling at Nusa Penida in mola season cuts visibility, and wet-season runoff lowers it elsewhere.
- Getting there
- Moderate — Reachable but with some friction: a 2.5h overland transfer.
- Experience
- Range is wide. Tulamben's Liberty wreck and Amed's macro sites are fine for Open Water divers. Nusa Penida is different: Crystal Bay, Blue Corner and Manta Point can carry strong and unpredictable currents, including down-currents along the walls, and most operators require Advanced Open Water plus current experience for the Penida and south-of-Padang-Bai sites.
Nearest airports
- DPS — Ngurah Rai International Airport (Denpasar) (Bali's only airport; direct international and domestic flights, then a road transfer to the dive base (Sanur, Tulamben, Amed or the west))

Worth knowing before you book
- Nusa Penida's Crystal Bay and Blue Corner get strong, shifting currents and down-currents; several sites are genuinely advanced-only, not for new divers.
- Mola season means cold water: upwelling routinely drops Nusa Penida into the low 20s and thermoclines have hit about 19°C, so a 5mm suit (or 3mm plus hood) is needed while the rest of Bali stays 27-29°C.
- Mola sightings are seasonal and never guaranteed; peak is August-September, and cold-water dives can be cut short or aborted on strong-current days.
- The Liberty and Manta Point are busy: get to Tulamben at dawn before the south-Bali day-trippers arrive, and Manta Point can be crowded with divers and snorkellers.
- Wet season (roughly December-March) brings rain, runoff and reduced visibility at many sites, though diving continues year-round.

Note on the data: Mola season boundaries and peak (roughly July-November, peaking August-September) are well corroborated across operators but vary year to year. Water temperatures are interpolated from published seasonal ranges: most of Bali sits 27-29°C, while Nusa Penida upwelling minima (22-23°C, thermoclines near 19°C) are localised to the mola-season south sites. Prices converted from IDR two-dive package rates. Site coordinates are approximate. Water temperature: maxC reflects the 27-29°C most of Bali holds year-round; the low minC values from July to October are the cold Nusa Penida upwelling in mola season, where water commonly drops to 22-23°C and thermoclines have been reported near 19°C, not a temperature felt across the whole region. Access: Fly into Denpasar (DPS); road transfer runs roughly 30-45 min to Sanur, about 2.5-3h to Tulamben/Amed, or 3-4h to the west, and Nusa Penida sites are a 30-45 min boat crossing from Sanur.
