Neptune's Arm - Quirimbas Archipelago
Blue Cavern, off the California coast, offers a genuine cave diving experience. It’s a narrow entry that opens into a larger chamber, where light filters in from above, creating a deep blue glow. Visibility can vary, but on a good day, the play of light and shadow is impressive. This site is definitely one for experienced divers comfortable in overhead environments, not a place to try out new gear.
