The boat eases away from the harbor and the shoreline slides back: a five‑minute wake and the water opens into a bowl of vivid blue. Light funnels through the cave mouth and the sea pushes color across the rock like a living filter. You enter with a guide at your side, fins first, and the cave’s sapphire glow frames schools of reef fish that ignore your intrusion.
