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.

The short version

Known forUSAT Liberty at Tulamben.

Main tradeoffThe headline animals are not on Bali itself: mantas and sunfish mean a day trip across to Nusa Penida, which is a longer, rougher and more demanding day than diving the main island.

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.
