The boat slips away from L'Estartit's low-lying harbor and the Med opens like a cool forehead; beneath the surface, Posidonia meadows hold small lives steady while currents test your balance. In twenty minutes underwater you move from sunlit chop to a quieter world where seabream and wrasse dart through rocks and an octopus vanishes into a crevice as if the seabed itself is rearranging to hide it.

The boat slips away from L'Estartit's low-lying harbor and the Med opens like a cool forehead; beneath the surface, Posidonia meadows hold small lives steady while currents test your balance. In twenty minutes underwater you move from sunlit chop to a quieter world where seabream and wrasse dart through rocks and an octopus vanishes into a crevice as if the seabed itself is rearranging to hide it.
The Costa del Montgrí sits on a coastline shaped by Miocene limestone and long coastal plains. Fishermen from Torroella de Montgrí have worked these waters for generations; their small harbors and stone watchtowers speak to a pragmatic relationship with the sea. The park’s protected status preserves Posidonia seagrass meadows that act as nurseries for many Mediterranean species and stabilize the shore.
Practicalities are straightforward: this is an introductory ‘diving baptism’ led by certified instructors, with SCUBA equipment provided and a short briefing before a gentle descent. Expect a 20-minute bottom time during an overall 80-minute activity; visibility is usually high in summer and spring, lower with wind or runoff. Wear a swimsuit under your wetsuit, drink water before boarding to avoid dehydration, and practice equalizing early—ears are the common limiter.
Book with a clear medical form if you have any conditions; operators limit participants to keep group sizes safe and immersive. Whether it’s your first breath underwater or a brief return to diving, the Montgrí offers a concentrated taste of Mediterranean marine life in a well-managed reserve.
