    StandoutDramatic cave topography

    Painted Cave, off Santa Cruz Island, lives up to its name with colourful algae painting the cavern walls. It’s one of the largest sea caves in the world, offering a long, dark penetration for experienced cave divers comfortable with low light and tight spaces. Inside, the water can be surprisingly calm, a contrast to the often-lively conditions outside. We’ve seen sea lions darting in and out, adding to the dramatic atmosphere.
