Wunderweg: Achensee Natur Erlebnispfad
The "Achensee Natur Erlebnispfad" in the Nature Park Karwendel follows the Obere Seebergsteig and offers a 3.4-kilometre journey through the local flora and fauna, featuring eight educational stations. Guided by forest ranger Linda and using an interactive app activated by scanning the QR code at the start of the trail, visitors can discover the region's biodiversity. Make sure that location access is enabled on your phone. The app includes learning modules and quizzes specifically designed to engage children. This trail is perfect for families looking to enjoy and learn about nature together. 
Please note that the app is only available in German.
