Natural Park Aquarium Boat Trip

This three-hour boat trip from San Antonio covers Ibiza's northwest coastline at a deliberate pace. You'll visit Cap Blanc Aquarium, an old lobster nursery tucked inside a sea cave and home to endemic Pityusic species, then cruise past Cala Gración, Cala Gracioneta, Cala Salada, Cala Saladeta and Punta Galera. The route ends at Margaritas Islands, a protected nature reserve where a 45-minute swim stop lets you use snorkelling gear or view the seabed through the glass-bottom boat hull. Refreshments include water, soft drinks, sangria, white wine and beer, plus fresh fruit and savoury snacks after swimming. The trip runs Mondays, Wednesdays, Thursdays and Saturdays, departing San Antonio at 11:00am. Check in at the Captain Nemo kiosk in the port, in front of the Egg roundabout, arriving 30 minutes before departure.
