This is smooth skate along the famous Barcelona beach.
But you have to be very careful, I almost died twice. First time i almost died laughing on all the ridiculous electric scootery things people can rent to try to go around the city, usually on guided tours. One was like electric scooter and home chair conceived an offspring inside Fukushima nuclear reactor. And the other like Pat a Mat trying to build flying carpet out of wheelbarrow and RC car. Later i was almost ran over by a i-dont-know-what-i-m-doing-on-that-thing-but-probably-the-best-i-can-do-is-to-grab-on-those-handels turist. I wasn’t laughing any more.
There are 2 skating parks along the way and some nice spots to do some tricks. You can see them here: http://www.barcelonaskatepark.com/barcelona-skate-spots/
