About this tour
When Lily from our team took this 3-hour boat run along Ibiza's northwest coast, she found a solid mix of geology, swimming, and downtime. The boat leaves San Antonio and swings past several coves — Cala Gració, Cala Salada, and others — before stopping at the Aquarium Cap Blanc, a sea cave where you can spot local marine life. The captain talks you through the coastline and island history as you cruise. The highlight is a swim stop at Islas Margaritas, a protected reserve with snorkel gear on hand and fruit plus drinks waiting after. It's the kind of tour that suits couples, small groups, and families after a gentler water day.

- Four named coves — Gració, Gracioneta, Salada, Saladeta — plus sea caves

- Snorkel kit and water equipment included on board
- Fresh fruit platter and drinks (beer, sangria, wine) post-swim
- Relaxed pace suits mixed fitness levels and family groups
What to expect
The boat departs from San Antonio and spends the first hour or so cruising the northwest edge, with the skipper pointing out coves and rock formations. The Aquarium Cap Blanc is a working natural cave — you'll lean over the rail to spot fish darting in native habitat rather than a formal aquarium setup. Lily noted it's peaceful but brief. The real meat of the tour is the Islas Margaritas stop: anchor up in shallow, transparent water where the reserve rules mean it stays quiet and unspoiled. You get maybe 45 minutes to an hour in the water with snorkel gear or just swimming. The boat crew set out fresh fruit and a drinks station (including alcohol options) so there's no scrambling after.
Pacing is unhurried. You're not rushing between ten sights; instead it's a coastal drift with one main activity. If you're after high-energy or lots of stops, this will feel loose. If you want a morning or afternoon afloat with a proper swim and no hard sell, it fits the bill.

Good to know
This tour works if you want to tick off northwest Ibiza without a full-day commitment. The snorkel gear is there if you want it, but swimming without it is fine too. Fruit and a proper drinks spread (wine and beer included, not just water) add value. The boat suits prams and service animals, so families and people with mobility gear have options. No serious fitness demands.
The Aquarium Cap Blanc is a viewing stop, not a dive or close encounter — expect a quick peek from the boat. Weather can close this tour in rough conditions; northwest swells do happen even in summer. The three-hour slot means you're committed to early-morning or early-afternoon timing. If you're hoping for lively watersports or competitive snorkelling, this is more sedate. Group sizes aren't specified, so don't assume intimate; you could share the boat with 30 others.
Bring sunscreen, a rash vest if you burn easily, and a light layer for the boat (sea breeze). Wear shoes you can slip off easily. Inclusions: snorkel kit, fruit, water, soft drinks, beer, sangria, white wine. Not included: lunch, transfers beyond San Antonio. Public transport gets you to the dock.
