Festa del Mar (Sea Festival)

Sant Carles de la Ràpita earns its living from the sea, so it makes sense the town sets aside a day each summer to let you have a go at the watersports it's known for. The action centres on the La Cabanya waterfront, where nautical activities and experiences are laid on for the day. Expect a hands-on, try-it-yourself feel rather than a stage show.

It's an easy one for families and curious newcomers, so you can dip into a few things, watch the boats come and go, and get a feel for life on this sheltered corner of the Ebre delta. The full programme tends to land closer to the day, so it's worth a quick check before you set out. Pleasantly low-key, and a gentle way to spend time by the water.
