Aplysina - Cousteau Reserve

Aplysina. Even the name whispers “sponges,” and trust us, it delivers. We love how this site, shallow as it is at just 11 metres, just feels… *soft*. It’s not about dramatic drop-offs or roaring currents here. It’s a gentle wander through fields of those fantastic rope sponges, golden and purple, some as thick as your arm, others twisting upwards like corkscrews. You’ll also spot plenty of barrel sponges and pipe sponges, creating a maze of nooks and crannies. The light filters through the water beautifully, dappling the sand and making the sponges glow. We’ve found cowfish peeking out from behind a particularly chunky barrel sponge, and those red cushion sea stars just pop against the muted corals. Keep an eye out for brittle stars too, their tiny arms waving from every crevice; there are so many varieties here. This is a perfect site for photographers, especially macro fans, or anyone who enjoys a relaxed, detailed exploration. It’s also our pick for a really pleasant second dive, or for those days when you just want to take it slow and soak it all in.
