Mallorca and Cabrera make one of the Mediterranean's easiest mixed-activity dive trips: fly into Palma, base on Mallorca, then choose local shore dives, short day boats, marine reserve trips or a more regulated Cabrera excursion. Expect limestone walls, caverns, Posidonia seagrass, grouper, moray eels, octopus, barracuda, rays and wrecks in clear blue water. The best overall window is May to October, with May to June and September to October giving the easiest blend of warm water, reliable boat schedules and fewer peak-summer crowds. Cabrera adds a national park layer: navigation, mooring and scuba are permit-controlled, and land services are minimal. That makes it feel more remote than its map distance suggests, while Mallorca keeps logistics simple for non-divers, families and training days.
