    ## Sea tour highlights

    Eco catamaran and harbour cruises show Barcelona from the water: skyline, port infrastructure and coastal light — look out for sustainability credentials when booking.

    ## Practical advice

    - Book sunset cruises for dramatic colours; bring a windbreaker.  
    - Check operator sustainability claims (electric or low‑emission vessels, partnership with conservation groups).

    ## Photo tips

    - Shoot towards the city as the sun drops for reflective water compositions; stabilise with higher shutter speeds if shooting handheld.
