The walkway in Mogelsberg, near the city of St Gallen and its Unesco-protected abbey, offers views over the Necker Valley and even as far off as the dramatic Churfirsten mountain range and the Appenzellerland region.
The pram-friendly canopy walk is open daily until October and entry costs 15 francs for adults and 8 francs for children.
There is also a forest playground for children underneath the walkway, along with barbeque areas.
Construction of the walkway, a first for Switzerland, involved over 60 tonnes of steel and cost around 3 million francs according to regional daily St Galler Tagblatt.
Authorities hope the project will help boost tourism in a region which is often overlooked by visitors.
