Sagrada Família → Park Güell

Both of these belong to Antoni Gaudí, and walking between them is effectively a tour of one architect's imagination stretched across two very different projects — a still-unfinished basilica that's been under construction since 1882, and a public park built as a failed real-estate development that Barcelona quietly turned into one of its best free attractions.

The route climbs steadily north out of the Eixample district, Barcelona's grid-planned nineteenth-century expansion, up into the hillier Gràcia neighborhood before the final push to Park Güell's elevated entrance. This is the one genuinely uphill walk among this site's European routes — nothing technical, but a steady enough grade that fifty minutes at "comfortable pace" will feel more like exercise than a stroll.

The Sagrada Família remains privately funded and still under construction more than 140 years after Gaudí began it — current estimates put completion sometime in the 2030s, which means every visitor for the last century and a half has technically seen a work in progress. Park Güell, by contrast, was meant to be an exclusive gated housing development for Barcelona's wealthy; only two houses were ever built before the project failed and the city bought the land, turning Gaudí's fantastical gatehouses, tiled serpentine bench, and mosaic salamander into a public park instead.

At roughly 2.5 miles of uphill city streets, this comes out to approximately 5,500 steps for an average-height adult at a relaxed pace, per the standard conversion this site uses — though the elevation gain means your legs will register more effort than a flat 2.5-mile walk elsewhere on this site.

Both sites require timed-entry tickets booked in advance, especially in peak summer months, so this isn't a walk to do on a whim if you actually want to go inside either landmark rather than just view them from outside. Buy both tickets before you start walking.

The reward for the climb: Park Güell's main terrace looks back out over the entire city toward the Mediterranean, with the Sagrada Família's spires visible in the distance below — the same building you started at, now shrunk to a single recognizable silhouette in a much larger skyline.
