Easy, in the village
The jewel (by boat)
Calm sea
Most spots
Southern Mallorca has some of the clearest, most alive water on the island, thanks to its Posidonia seagrass meadows. We live in Colònia de Sant Jordi and have snorkelled here since we were children: this is our honest guide to the best spots, from the easiest (right in the village) to the most spectacular (the Cabrera marine reserve), with the best season and how to do it safely and respectfully.
Data: Open-Meteo.
Why the water is so clear here
The southern water is this clear thanks to the Posidonia meadows, the sea plant that filters the water and shelters fish, starfish and octopus. It’s protected, so you mustn’t stand on it or anchor over it: it’s exactly what lets you see so much here. Mixed rock-and-sand bottoms dotted with Posidonia are where you’ll find the most life.
Cala Galiota: the easiest, in the village
Right in Colònia, Cala Galiota is rocky with very clear water and an easy entry: perfect to start, for children who already swim, and for a quick masked dip without travelling. You’ll spot fish over the Posidonia just metres from shore. It’s our number-one pick for the first day.
The port rocks and Es Dolç
Around the port and the rocky areas by Es Dolç there’s good snorkelling close to home too. Watch for boat traffic near the port: stay close to shore and use a marker buoy if you venture out.
Cap de ses Salines: crystal water
At Mallorca’s southern tip, Cap de ses Salines has rocky shores with spectacular clarity. It takes a bit more effort (and a car) and you should check the forecast, as wind makes it uncomfortable. With a calm sea, it’s among the best in the area.
Cabrera, the jewel of the reserve
The best snorkelling of all is in the Cabrera National Park, a marine reserve with crystal water and abundant life. You get there by boat from Colònia; the stop at the Cova Blava and the archipelago’s coves are unforgettable. See the Cabrera excursion.

The islets by kayak or paddleboard
Off the coast there are small islets (such as Na Moltona) with beautiful bottoms, ideal for combining snorkelling with kayaking or paddleboarding. Go with a calm sea, judge the distance well and don’t go alone.
Safety and respect
Head out in the morning (flatter sea and better light), use fins and a buoy, wear sunscreen and never snorkel alone. Don’t touch or take anything, don’t feed the fish and don’t stand on the Posidonia. Watch for boats and currents at the headlands. With common sense, southern Mallorca is an aquarium.

FAQ
Where is the best snorkelling in Colònia de Sant Jordi?
To start, Cala Galiota in the village (easy and very clear). The best of all is Cabrera, the marine reserve, reached by boat.
Is there good snorkelling for beginners or children?
Yes, Cala Galiota is ideal: rock, clear water and an easy entry, with fish near the shore. Always with children who can swim and supervision.
Do I need a boat to snorkel?
Not for the village spots (Galiota, port, Es Dolç) or Cap de ses Salines. For Cabrera and the islets a boat, kayak or paddleboard helps.
When is best?
In the morning with a calm sea; wind clouds the water and complicates the headlands. Summer offers the warmest water.
Is it safe?
Yes with care: fins, a marker buoy, don’t go alone, watch for boats and currents, and respect the protected Posidonia.

Who it’s for (and who it isn’t)
Great if you want clear water and rocky, seagrass seabeds.
Skip it if you expect a coral reef: this is the Mediterranean.
Local tip: the best seabeds are the rocky coves (s’Almunia, Es Pontàs); bring water shoes and go when the sea is calm.
