Perimukweg Herznach

Theme trailHiking trail
Time required: 1 hour 36 minutesLength: 5.89 km

Jurapark Aargau - Perimuk the Jura dinosaur wants to discover the hidden natural treasures around the village of Herznach. Will you join?

Perimuk, the Jura dinosaur, invites you to a discovery route to ringing toads, stone snails, and bright forests. Equipped with the photo hiking map, available at the start or at the Jurapark office, the children find the right way themselves – which motivates them to hike! True explorers get a research set before starting, consisting of an explorer booklet and expedition materials. With this, children can discover small animals along the path, study stones, and solve exciting tasks. Perimuk is already looking forward to many young explorers who will discover the treasures around Herznach with him!

The pure hiking time is about 2 hours. Including puzzles, the adventure takes about 4 hours.

Safety advices

The Weichle hammering site is permanently closed for safety reasons. Please do not enter the site. The puzzles from the explorer booklet are still a great experience and work well without the hammering site. Tip for enthusiastic fossil hunters: On every 1st Sunday of the month from April to October, the hammering site at the Herznach mine is open from 1:00 pm to 5:00 pm during the open mine days, and hammering is possible. The Gruhalde hammering site in Frick is accessible all year round; hammer and chisel must be brought along, and entering is at your own risk.

Signalization

The path is not signposted. The route is found by the children themselves using the photo map.
