Natural Park Aquarium Boat Trip

The Natural Park Aquarium Boat Trip departs from San Antonio's port four times weekly, heading northwest along Ibiza's protected coastline. The three-hour journey stops at Cap Blanc Aquarium, a former lobster nursery carved into a sea cave where endemic Mediterranean species still shelter. En route you'll pass Cala Gració, Cala Gracioneta, Cala Salada, Cala Saladeta and Punta Galera before reaching the Margaritas Islands nature reserve. A 45-minute swim stop lets you explore via snorkel or glass-bottom boat viewing. The water here is clear enough to see the seabed without getting wet. Afterward, fruit and light snacks come with drinks—water, soft drinks, sangria, white wine and beer included throughout. Depart Monday, Wednesday, Thursday or Saturday at 11:00am from Captain Nemo's kiosk at San Antonio port. Arrive 30 minutes early.
