"The Gaudí Experience is a great introduction to one of the world's great architects for younger tourists with limited attention spans and walking power. It’s a 4D simulator that takes you through Gaudí’s wacky brain, with immersive sounds, moving seats and water jets. Imagine a ride at a fair that calm enough for your kids’ grandma, but with enough similarities to an iPad to keep the young tech addicts interested. If that whets the appetite, head to Park Güell, literally three minutes’ walk up the road (you have to pre-book tickets to visit the best parts, like the lizard, but you can enter the general site and stroll for free). Elsewhere, the stunning Casa Batlló has interactive smartphone guides with VR pop-ups. They make the audio genuinely engaging – if you get stuck working the controls, simply ask your seven-year-old how it’s done." - Gemma Askham
