The Glasi Park is a small paradise for young and old. It is open and accessible at all times.
Enjoy a peaceful picnic in pleasant surroundings or play exciting games with your children. The 7-meter-high marble run with long slide, various marble games, a quartz sand pit (quartz sand is the most important raw material in glass production), playground equipment and other games offer children of all ages every kind of adventure. Glass marbles can be obtained at the dispensing machine (10 pieces cost Fr. 5.–).
Dragon “Leandra” watches over the park. Climbing on the dragon is allowed!

On 29 June 2010 the only glass labyrinth in Switzerland was opened. Prepare to be enchanted! Listen to the Glasi sounds – enjoy the light show – and try to find the way out! Video
An exciting adventure which expresses all the fascinations of glass. You are more than just a spectator – you will find you are really involved when you immerse yourself in a world of glass. Swiss television featured a report on the glass labyrinth in its Schweiz Aktuell (Switzerland Today) programme. The glass labyrinth is a joint project by Glasi Hergiswil and Glas Trösch.
Opening times: Monday to Friday 9.00 am to 12.00 noon and 1.30 to 5.00 pm; Saturdays 10.00 am to 4.00 pm. Admission CHF 5.00, children (up to 10 years of age when accompanied by an adult) are free of charge. The cash desk will give you slippers and gloves for your exploration of the labyrinth.
For each CHF 50.00 spent at our shops on the same day, presentation of your ticket will entitle you to a CHF 5.00 reimbursement.

The Glass-Blowers

die glasmacher

You have an ideal view of the glassmakers’ platform, and can observe our craftsmen in their rhythmical working activity. Find out for yourselves what craftsmanlike skill it takes to form glass out of the glowing mass, blow it, and cast it. Our glassmakers come from Portugal and Italy. They work from 9.00-13.00 and from 13.30-17.00, Saturday from 8.30-12.30 and from 13.00-16.00. In the old days we used to train apprentices at the glass works. Now you have to go abroad for an apprenticeship – at places like the Glass Technical College in Zwiesel, Germany.
