The catamaran slips out of the harbor and the coastline of the Costa Brava unspools—rocky headlands, low pine slopes and the clipped silhouette of Montgrí rising like a sleeping figure above the bay. Salt spray cools the face as the boat crosses the Gulf of Roses; the sea seems to press forward, offering a clear window into life below.

The Medes Islands are small, rocky outcrops with a long human story: once a refuge for fishermen and, by rumor and record, pirates. Geologically they’re the remains of resistant rock standing against a coastline shaped by ancient sea levels and modern erosion, surrounded by dense beds of Posidonia oceanica—vital seagrass that sustains the marine ecosystem.
Culturally the route brushes Greek and Roman shores at Sant Martí d’Empúries, where ruins speak to centuries of coastal trade, and modern fishing villages like L’Estartit that celebrate seafood and local markets.
Practical guidance sits close to the poetic: passengers will use the catamaran’s underwater viewing rooms to observe reefs, boulders and schools of fish without getting wet, then spend about 90 minutes ashore in Estartit—enough time to walk the market or enter the water from the beach with a snorkel.
Bring reef-safe sunscreen, a light wind layer and water; schedule trips in morning or late afternoon for calmer seas and clearer views. Respect the marine park rules—no anchoring on seagrass beds and keep distance from protected areas. The trip is accessible and family-friendly, offering an efficient way to see submerged life and coastal history in one outing.
