    StandoutExceptional marine biodiversity

    Angel Window in Sulawesi is a good choice for divers who enjoy exploring caves. Entry involves swimming through a narrow opening, which widens into a cavern illuminated by light shafts from above. You'll find yourself in a large chamber with a sandy bottom, keeping an eye out for the odd reef shark resting in the deeper sections. It’s not a long dive, but the light show is worth it, especially midday.

    Safety Notes

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