Blue Lagoon, Comino: swimming and snorkelling in Malta's turquoise channel

What Blue Lagoon actually is, and the swimming and snorkelling

Blue Lagoon is a narrow channel between Comino and the tiny islet of Cominotto, floored with pale sand that turns the shallow water an unusually bright turquoise. The main swim zone near the beach is calm and shallow, which makes it forgiving for weaker or open-water-nervous swimmers, while the water clarity is excellent for casual snorkelling.

For snorkelling, the interest is around the edges rather than the sandy middle: the rocky sides of Cominotto and the channel walls hold small fish, and visibility is often superb on a still morning. This is easy, warm-water snorkelling, not a rich reef dive, so set your expectations towards scenery and light rather than big marine life.

If you want more than a paddle, the same boat trips usually take in the nearby Comino caves and the Crystal Lagoon on the far side, which are quieter and just as clear.

When to go, and being honest about the crowds

The swimming season runs roughly May to October, when the sea is warm and ferries are frequent. June and September are the pick: warm enough to swim comfortably, without the full weight of the July and August peak.

Crowds are the single biggest downside and they are not exaggerated. The bay that once saw up to 12,000 people a day is now capped at around 4,000 at a time, and even at that cap the middle of a summer day is packed with tour boats and swimmers. Arrive at opening, around 7am to 9am, or come back in the late afternoon after about 4pm when the day-trippers head for their return ferries. Midday, roughly 11am to 3pm, is the crush.

Out of season the lagoon is quiet and beautiful but the boat schedule thins right out and kiosks may be shut, so check sailings before you commit.

How to get there and how to do it

Comino has no cars and no resort of note; you come by boat and leave the same day. Public ferries run from Cirkewwa and Marfa on Malta's northern tip and from Mgarr on Gozo, crossing in roughly 10 to 25 minutes. As of 2026 expect somewhere around 10 to 15 euros return, and pre-book online, but verify the current fare before you rely on it.

Since 1 May 2025, anyone stepping onto the shore must hold a free timed access pass booked through Malta's official Access Management System (the government blcomino portal). Entry is checked at the jetty and landing without a valid pass can mean a fine. The pass itself costs nothing; it is a numbers cap, not a fee.

A useful loophole for swimmers: if you take a small private or self-drive boat from Cirkewwa and stay in the water rather than landing, you do not need the pass, and you get quieter corners away from the main beach. Guided operators run everything from big group ferries to jet-ski safaris and private charters, so pick by how much crowd you can tolerate.

Safety note: shelving depth, no full lifeguard cover, and jellyfish

The lagoon is easy but not risk-free. It is shallow and warm near the beach, around a metre and a half, then shelves away quickly to ten metres or more as you head out into the channel, which catches out weaker swimmers who drift beyond the sandbar. Lifeguard cover, where present, is focused on the main beach, not the whole bay or the rocky snorkelling edges, so treat the deeper water and the Cominotto side as unsupervised.

Boat traffic is heavy in season; stay inside marked swim areas, keep clear of the jetty and moving craft, and be visible if you snorkel out to the rocks. There is little natural shade and the reflection off pale water burns fast, so plan for sun and water.

Mauve stinger jellyfish appear seasonally, most often in deeper open water rather than the shallow beach zone. Stings are painful but not lethal; rinse with seawater, remove tentacles carefully and carry a sting-relief spray. Check the beach warning flags before you swim.

Entry, cost and practicalities for the travelling nomad

Malta is in the Schengen Area and the EU. Many nationalities, including UK, US, Canadian and Australian passport holders, can visit visa-free for up to 90 days in any rolling 180-day period; the EU's ETIAS travel authorisation is expected to come into force during late 2026, so check whether it applies to you before you fly. Confirm your own nationality's rules against an official source, as these change.

This is a trip, not a nomad base: there is nowhere on Comino to reliably work, and you should not plan around wifi or a desk here. Base yourself in Malta or Gozo, treat Blue Lagoon as a morning out, and bring water, sun cover, reef-safe sun cream and cash for the kiosks. Prices and pass rules are current as of 2026; verify before you rely on them.
