Schmugglis Adventure Playground, Trübsee

Schmugglis Adventure World, Trüebsee
Welcome to the family paradise of Trübsee! Many years ago, smuggler Engelbert and his mule Schmuggli hiked from Engelberg over the Jochpass to Engstlenalp and on to Italy. On the treasure hunt, you look for the treasures that they hid on their adventures. On the Sbrinz Trail, you solve puzzles and try to stay undetected by customs officers and witches. The playground, the mule camp and Schmugglis Camp round off the great family offer.

One of the many playgrounds around the Trüebsee... These are also very crowded on weekends...

There is an adventurous treasure hunt with various stations around the Trübsee. You can get the corresponding map at the Trübsee station, for example.
Very nice playgrounds with rest and barbecue facilities.
