Barcelona: Eco Catamaran Coastline Tour

Sail calmly in an ecological catamaran propelled by solar panels and enjoy the panoramic views of the coast of Barcelona.

The catamaran will leave from Port Vell, where you can snap monuments like the World Trade Center and the biggest yachts in the city. That should spruce up your Instagram feeds.

During the walk, get a unique perspective of Barcelona like you've never seen it before, including a visit to Puerto Olympic, a marina that hosted the sailing events for the 1992 Summer Olympics.

Opt to buy the audio guide app on board and discover the secrets of the Sagrada Familia, Montjuic, Ramblas del Mar, Port Olímpic and more. On the boat, take advantage of the bar service - every purchase you make goes towards marine conservation.
