Blue Grotto Malta by Boat: See It on a Private Charter
The Blue Grotto in Malta is one of the most photographed natural sites on the island, and almost everyone sees it from exactly the wrong place. The clifftop viewpoint at Wied iż-Żurrieq gives you a look down at the arches from above. It’s fine for a photo. But at sea level, with the limestone caves rising directly overhead and the water glowing blue beneath you, it’s a completely different experience.
Malta Catamaran Charters has been running private day charters to the Blue Grotto and Malta’s south coast for over ten years. This page covers what the Blue Grotto is, how to get there, and how to see it properly.
What Is the Blue Grotto in Malta?
The Blue Grotto is a cluster of sea caves and natural arches cut into the limestone cliffs near Wied iż-Żurrieq, on Malta’s south coast. By road it’s about 40 minutes from Valletta; by sea it feels like a different world.
The name comes from what happens to the light on a calm morning. Sunlight hits the water, bounces off the white sandy seabed, and fills the caves with a shade of blue that looks almost artificially vivid. It’s at its best between roughly 9am and midday. Later in the day the effect fades, but the caves are still worth seeing.
Most visitors come for the caves, but the south coast around them is genuinely one of the best stretches of coastline in Malta. Limestone cliffs, clear water, and hidden coves that don’t appear on any tourist map. The reason most people never see it is because you can only reach it by boat.
Blue Grotto Boat Trips: Two Ways to Visit
There are two ways to visit.
The first is by road. Drive to the small harbour at Wied iż-Żurrieq (about 40 minutes from Valletta) and board one of the traditional dghajsa boats that run short trips through the arches. The trips take around 20 minutes and give you a quick look at the caves from the water. A decent option if you’re driving the south coast and want to add a stop.
The second is a private catamaran charter that includes the Blue Grotto as part of a full day on the water. You depart in the morning, head south along Malta’s east coast, and arrive at the caves with time to anchor, swim, and actually spend time there. No fixed 20-minute window, no queue. The route also takes you along a coastline that is genuinely hard to access any other way.

Visiting the Blue Grotto by Private Boat: What to Expect
A full-day charter with Malta Catamaran Charters runs around 8 hours. You board at Roland Marina in Ta’ Xbiex or at Tigné Seafront in Sliema in the morning, head south along the east coast, and arrive at the Blue Grotto roughly 90 minutes later. From that point the day is yours.
Most groups anchor near the cave arches, swim at the base of the cliffs, and snorkel along the rocky edges. The water along this stretch of the south coast stays clear and calm for most of the season from spring through to autumn. Our skippers time the route specifically to arrive in the morning, when the light inside the caves is at its strongest.
We have boats for groups of up to 55 people, from a 10-guest sailing yacht up to a catamaran that takes 55, and bigger groups can book two or three boats together. Whatever the group size, there’s a boat that fits.
What’s included on a day charter:
- 8 hours on the water, with skipper and fuel included
- Swimming and snorkelling stops at the Blue Grotto and along the south coast
- A stand-up paddleboard on every catamaran and the sailing yacht
- Food and drinks: bring your own, or ask us about our BBQ and food and drink packages
- Boarding at Roland Marina, Ta’ Xbiex, or Tigné Seafront, Sliema, at no extra cost; pickups from other places on request
If you want to combine the Blue Grotto with a stop at the Blue Lagoon at Comino, we run that as a combined route on the same day. It’s a long day and regularly comes back as one of the best things people did on their trip.
Best Time to Visit the Blue Grotto in Malta
April to October is the best window to visit the Blue Grotto in Malta because the sea is usually calm, the water is clear, and swimming is pleasant. We run private charters all year, though, so in October, November and the winter months you can still see the Blue Grotto by boat on calm days, often with the caves almost to yourselves. We check the wind and sea the day before and only go when conditions are right.
Go in the morning for the strongest light inside the caves, since the reflection effect peaks before noon and drops off through the afternoon.
In July and August the clifftop fills up fast and the dghajsa queue builds from mid-morning. However, on a private charter you’re away from all that, but an early start to the day will help if you want the bay mostly to yourselves.
Blue Grotto Malta: Frequently Asked Questions
Is the Blue Grotto in Malta worth visiting?
Yes, especially from the water. The clifftop viewpoint gives you a look down at the arches, but doesn’t show you much of what makes it special. One of the most impressive natural spots in Malta is looking at the cave arches from sea level and seeing the light refract through the water below. In addition, the surrounding south coast is worth the trip on its own.
Can you swim at the Blue Grotto in Malta?
Yes. The water around the caves is clear and sheltered on most days from April to October. On a private charter you anchor in the bay and can swim freely near the caves. The short dghajsa trips from the harbour at Wied iż-Żurrieq do not include swimming.
How long does a Blue Grotto boat trip take?
The traditional dghajsa trips from the harbour take around 20 minutes. A full-day private charter with Malta Catamaran Charters runs approximately 8 hours, with time to swim, eat, and explore the south coast at your own pace.
How do you book a Blue Grotto boat trip in Malta?
You can book a private day charter directly online. If you have a larger group or want to talk through the route first, get in touch and we’ll get you the correct boat for your situation.
Can you combine the Blue Grotto and the Blue Lagoon in Malta on the same day?
Yes. Malta Catamaran Charters runs a combined route covering the Blue Grotto on Malta’s south coast and the Blue Lagoon at Comino on the same day. It’s one of the most popular routes we run in summer.
How far is the Blue Grotto from Valletta?
About 40 minutes by road or around 90 minutes by sea. The road option gets you to the clifftop viewpoint and the short dghajsa boat trips. The sea option gives you a full day at water level with time to swim and explore the south coast properly.
What is the best way to see the Blue Grotto in Malta?
By private boat at sea level, arriving in the morning when the light inside the caves is at its strongest. The traditional dghajsa trips from Wied iż-Żurrieq give you a quick 20-minute look. A private catamaran charter gives you the full experience.
