Board a catamaran from Roses for submarine viewing pods, a swim in Cala Murtra, and coastal geology at Cap Norfeu. This 2.5‑hour outing pairs easy ocean access with protected marine scenery—ideal for families and first‑time snorkelers.
More ways to explore the area's outdoor wonders
The catamaran slips away from the Roses promenade and the town shrinks into white roofs and bobbing buoys. Sea spray nudges your cheeks; beneath the glass viewing pods a tableau of rock, Posidonia meadows and darting fish scrolls by like a living map. At Cala Murtra the captain eases the engines and the sub‑vision pods become aquarium windows — a shallow reef museum where olive‑green algae and sculpted rock faces frame small schools of fish.

Bring reef shoes
Rocky cove entries mean reef shoes protect feet on slippery stone and sharp algae; essential for comfortable water exits.
Use motion‑sickness prevention
Take a single dose of seasickness medication or wear acupressure bands if you’re prone to wobble on open water.
Protect optics and skin
A snorkel mask and high‑SPF reef‑safe sunscreen improve visibility and protect from the strong coastal sun.
