We end the day as we started it, by the sea, but this time aboard a catamaran to watch the sunset. Soon after leaving port, they unfurl the sails and shut off the engines. After sailing for a moment, and without losing sight of Barcelona, they stop the boat and invite us to take a swim in the Mediterranean; an invitation we are sure to accept. Back on board, we are served an aperitif of seasonal fruit and a glass of Cava, finishing up a great trip as the sun sets behind the Collserola Mountains.
