Two hours on a shared catamaran out of Port Olímpic — skyline, snacks and a drink.

Board at Port Olímpic, motor out past Barceloneta, and watch the city turn gold from the water. Open bar soft drinks and one alcoholic drink included, light snacks on board. Shared sailing — not private. Back at the dock after dark. Bring a layer; the wind picks up as the sun drops.
