Barreta de L'arbre is a classic boat dive on one of Mataró’s rocky bars, set inside a Special Conservation Area. The site is all about cracks, porous rock, and the small animals that hide in the gaps, so it suits slow scanning and camera time more than a fast pass. Expect octopus, conger eels, moray eels, lobsters, and nudibranchs in a compact Mediterranean profile.
