Historic Abrolhos wreck broken across chapeirões and reef growth.
This site is normally dived from licensed overnight or day boats already operating inside the park.
Naufrágio Guadiana is one of Abrolhos' classic wreck dives, with the broken hull spread between large chapeirões and reef structure rather than lying as a single clean outline. Divers follow machinery, anchor gear, and tilted plating through an artificial-reef setting that also draws resident groupers, schooling fish, and hard-coral growth.
