When it comes to Mediterranean snorkeling, few spots rival the Medes Islands for their vivid marine biodiversity and stunning underwater scenery. Based at the Unisub Dive Center in L’Estartit, this 1.5-hour snorkeling trip offers a chance to see a kaleidoscope of marine life in crystal-clear waters, guided by knowledgeable staff dedicated to safety and sustainability. It’s an experience that combines the thrill of underwater exploration with the comfort of well-organized logistics, making it a great choice for travelers who want a straightforward yet memorable adventure.
What I find especially appealing about this experience is the personalized attention provided by guides who really know their marine environment, and the small-group format that ensures everyone gets a good view and plenty of guidance. You also get all the gear included—mask, fins, wetsuit—so there’s no fuss about renting or bringing your own equipment. One thing to keep in mind is that the total activity lasts about 1 hour 30 minutes, which is perfect for those with limited time or looking for a light, engaging activity. However, some reviewers mention the need for a slightly larger wetsuit for comfort, especially during the boat crossing, so packing a little extra patience and a sense of humor helps.

From the dock, you step onto a boat that whisks you out to the islands. The ride itself lasts about 10 minutes, offering a chance to enjoy the views of the coast and the islands ahead. As some reviews mention, the boat can be quite full, so a wetsuit one size larger might be more comfortable, especially during the crossing.
The boat ride is a highlight for many—gentle waves, scenic coastline, and the anticipation of what lies beneath the surface. The crew, including your guide, will give you a briefing on the activity, safety tips, and what marine life you might see. The guides are praised for their professionalism, making sure everyone feels prepared and confident before entering the water.
