I spent some time in Barcelona, Spain recently. If you ever go, be certain to visit Sagrada Familia (a church that has taken almost 150 yrs to build and it’s not done yet!). Like Sagrada Familia – Parc Quell was designed by Fransico Goya. Other interesting sites were Palau de la Música where I saw a flamenco show and Hospital de Sant Pau . Lastly, If you’re up to it, hike the goat trail – not the domesticated wide and winding manicured trail – 4000 ft up to the Montserrat Monastery. It’s an investment of a couple hrs w/ no shortage of scratches & nicks, but worth it. Be sure to pack water – there’s no tourist traps on this hike!
