Set off from the quaint coastal town of L'Estartit on Spain’s Costa Brava for a snorkeling experience that reveals the underwater riches of the Medas Islands. Unisub Estartit SL offers guided trips into these protected isles, where the clarity of the Mediterranean showcases thriving posidonia seagrass beds, labyrinthine rock formations, and teeming marine life. This unique marine reserve carries the distinction of being one of Spain’s most important underwater habitats, attracting snorkelers who seek vibrant ecosystems alive with colorful fish schools and occasional sightings of octopuses or moray eels.
The Medas archipelago, composed of seven small islands, was declared a protected reserve in the early 1990s, sealing its fate as a sanctuary against overfishing and habitat degradation. As you float above the posidonia, a marine flowering plant that plays a critical role in oxygen production and coastal erosion control, you’ll notice how its swaying blades foster an environment for numerous species, including groupers and wrasses. The underwater caves carved from limestone cliffs invite careful investigation, offering a striking contrast to bright shoals darting through sunlit water.
Unisub Estartit SL stands out by focusing on responsible snorkeling tours that emphasize education and respect for delicate ecosystems. Their experienced guides equip guests with knowledge about local flora and fauna while ensuring the group's safety and minimal environmental impact. This approach has made them a cornerstone for ocean enthusiasts visiting Girona's coast. Whether you’re a family with budding marine biologists or an avid snorkeler seeking Spain’s hidden depths, this trip offers an accessible and exhilarating dive into one of Europe’s premier marine reserves.
