‪When it comes to history, art, and architecture Barcelona delivers: There's Gaudí’s iconic Basílica de la Sagrada Familia, the Picasso Museum, and the Gothic Quarter. But look beyond the landmarks and busy mercados and you’ll notice how nature steals the show—the city’s literally surrounded by it. On one side you’ve got three miles of gorgeous sandy beaches that give the neighboring Balearic Islands a run for their money, and on the other, the Serra de Collserola mountains, home to Parc de Collserola—one of the biggest city parks in the world. It’s probably why bike culture’s big here: Over 180 miles of bike lanes makes it easy to get around the Catalan capital. Spend a low-key afternoon cruising the revamped La Rambla (you’ll have to walk your bike once you hit the pedestrian-only drag) and stop for tapas and sangria. You can really do it all and we’ve got more ideas, below. ‬
