Here's a clever way to see La Aldea on foot without trailing behind a guide. You play a 1920s villager helping the local priest, Reverend Vicente Bautista, raise the money to reach Madrid and finally settle the town's centuries-old land row with the big landowners. Ten riddles steer you from the Church of San Nicolas through Plaza de La Alameda, past the old tomato-packing factory (now a small museum) and along Calle Real to the town hall, dodging the odd Civil Guard along the way.

It runs entirely in your phone's browser, so there's nothing to download and no charge. You set your own pace, with no fixed schedule, which makes it easy to break off for a coffee and pick the trail back up. A relaxed, low-effort way to get under the skin of a town most visitors only drive through.
