Vaillant Arena is an arena in Davos, Switzerland. It is primarily used for ice hockey and is the home arena of HC Davos. It holds 7,080 people, of which 3,280 are seated. Every year the Spengler Cup is played in this arena.
Major renovation of the arena started at the conclusion of the 2017-18 season to upgrade most of the stands and the concourse. The seating capacity will not be increased and the total cost should be around CHF 21 million. Construction began in 2018 and is expected to be completed by 2021.
