Blue Grotto vs Blue Lagoon: Malta's Two Blues Explained
Every summer, visitors book one expecting the other. The Blue Grotto and the Blue Lagoon are both spectacular, both very blue — and completely different places on opposite sides of the sea between Malta and Comino. Here's the two-minute version.
The Blue Grotto: sea caves you visit by boat or jet ski
A chain of sea caves in the limestone cliffs of Malta's south coast, where the water glows turquoise inside the caverns. You don't sunbathe here — you ride to it. Our 2-hour guided Jet Ski Safari (€275, 18+) arrives entirely from the sea, or you can take the skippered 28ft boat along the same coast from €180.
The Blue Lagoon: Comino's shallow swimming bay
A shallow, sandy-bottomed bay on Comino island with water so clear the boats look like they're floating on air. This one IS for swimming and snorkeling — our full-day trip from St Julian's costs €30 per person and departs daily at 10:00 until 31 August.
Important: Comino island requires the government entry QR (get it at blcomino.com/product/blue-lagoon) — it's mandatory and not included in any boat ticket. The Blue Grotto needs no pass.
So which one?
- •Want a full beach day of swimming and snorkeling → Blue Lagoon (Comino), €30
- •Want adventure, cliffs and caves in 2 hours → Blue Grotto safari, €275
- •Doing both is the classic combo — they're different days, different coasts
