Choose your preferred tour time when booking, then make your own way to the Colònia Güell information and visitor center to pick up your audio guide and keepsake guidebook. Set out to discover the highlights of Colonia Güell and Gaudi's Crypt at your own pace, exploring the area's terraced houses, school, historic factory, shops, gardens, and co-operative buildings. Wander through the 19th-century village as you listen to how modernist architects were commissioned by Eusebi Güell to house the workers from his nearby textile factory. Admire the Catalan folk architecture fused with modernist elements like turrets and trencadis mosaic tiling.  After your time in the village, make your way to the main attraction: Gaudi's Crypt, declared World Heritage site by UNESCO in 2005. Hear how Antoni Gaudi designed the church in 1882, and learn how the designer used it to test ideas for his main life work: The Sagrada Familia in Barcelona. Marvel at the architecture outside, then step inside to wonder at the soaring arches, spiraling columns, and two naves; built on different levels to blend into the surrounding hillside. The audio tour concludes after two hours; you are free to spend as much time in the area as you like.
