Naxos rewards divers with a varied site roster: boat-accessed reefs, walls, caves, canyons, and several wrecks, including the Marianna shipwreck and the Bristol Beaufighter aircraft. Most sites suit intermediate divers, though beginners have accessible options such as Amaras Reef and Mikri Vigla. The Common Octopus, Great Barracuda, Mediterranean Moray, and nudibranch species such as the Cratena Slug and Mediterranean Violet Aeolid are consistently observed. Conditions are most favourable from late spring through autumn.

Several sites are rated for beginners, including Amaras Reef, Black Rock, and the shore-accessible Mikri Vigla, which offers shallow reef and drop-off terrain. That said, the majority of the site roster is rated intermediate, so beginners will find a good starting point but will quickly have room to progress.
