More ways to explore the area's outdoor wonders
A low-profile boat slips away from L'Estartit's harbor and the Medes Islands come into view: rocky islets, sun-bright water, and the soft green of submerged meadows visible from the surface. Guides brief the small group, hand over snorkel kits, and point to the shallow bays where Posidonia oceanica carpets the seabed — a living nursery that gives the reserve its pulse.
