Cueva de la Luz is a guided boat dive near Cala Galdana with easy swim-throughs, a bright air chamber, and a shallow profile that suits relaxed divers and photographers. Plan it as a calm-water outing with a torch, a slow pace, and room for the afternoon light beam to do the work. The route is about filtered light, simple cave movement, and a mixed Mediterranean cast of groupers, barracudas, octopus, moray eels, scorpionfish, and nudibranchs.
