    StandoutExceptional marine biodiversity

    Goa TJG Arus offers an intriguing cave dive for those looking to explore Sulawesi's submerged geological features. The main draw here is the cavern itself, presenting a chance to navigate confined spaces. Visibility inside can vary, so a good dive light is essential. We'd suggest this site for experienced divers comfortable with overhead environments and focused on unique topography rather than abundant marine life.

    Safety Notes

    Overhead environment - never enter without proper cave/cavern training, redundant equipment, and a guideline.
