Natural Park Aquarium Boat Trip

Natural Park Aquarium Boat Trip explores Ibiza's northwest coast in three hours, departing from San Antonio at 11:00am. The route follows the shoreline past Cala Gració, Cala Gracioneta, Cala Salada and Cala Saladeta before reaching Cap Blanc Aquarium, an old lobster nursery carved into a cave. Here you'll see species endemic to the Pityusic sea through a glass bottom boat, then continue to the Margaritas Islands, a protected nature reserve where a 45-minute swim stop lets you snorkel and explore the seabed. The morning includes drinks—water, soft drinks, sangria, white wine and beer—plus fresh fruit and salty snacks. Depart Mondays, Wednesdays, Thursdays and Saturdays at 11:00am from Puerto de San Antonio. Check in at the Captain Nemo kiosk in front of the Egg roundabout and arrive 30 minutes early.
