The Experience

You arrive at Frick station with a printed barcode and a starting document, ready to follow a fox's trail through a puzzle that doesn't quite make sense yet. Most people expect a guided tour or a marked hiking path. Instead, you get a mystery: a famous dinosaur researcher vanished somewhere in the Jurapark Aargau, and the only way to find out what happened is to decode clues, solve tasks, and hop between stations on public transport. The fox's trail is permanent, but the story changes how you see every corner.

The Foxtrail works like this — you move on foot between posts, each one unique and hidden in the actual city. Some are attached to buildings, others are playful installations or technical pieces designed to reveal messages when you figure out how. You scan your barcode at each checkpoint, stamp your ticket, and the next clue appears. There's no guide walking ahead; it's your team solving the puzzle together, which means you move at your own pace and argue about what the cryptic message actually means. The trail takes you into the wet, dark underworld of Frick — literally underground passages where the dinosaur hunter might have gone — so bring a phone with a charged battery and a willingness to get a bit damp.

The whole Foxtrail experience in Jurapark Aargau is designed to be varied and strange. You'll use public transport to jump between locations, which sounds simple until you realize the clue is telling you to board a specific train or tram and get off at a station that isn't marked on any tourist map. It's not a race, but it's not leisurely either — most teams spend several hours working through the trail, and the puzzle only closes when you've solved enough to reach the final post. The physical fitness requirement is moderate; you're walking and thinking more than climbing, though the underground sections mean stairs and uneven ground.

Book your tickets at the departure station using your printed confirmation, keep everything safe, and stamp your tickets before you start. Bring your phone, a pen, and the willingness to look foolish while you're staring at a post trying to decode what the fox is telling you. Service animals are welcome on the trail.
